Laertes, from Greece, has been cooperating with AAK for 3 years, mainly purchasing standard parts of cartridge valves of HydraForce. Last year, he needed to purchase a hydraulic directional control cartridge valve benchmarking HydraForce to develop their pile driver, but AAK did not have the procedure for this cartridge valve, and then no further news from him. I thought he directly purchased from HydraForce. It was not until last December that Laertes asked me the fastest time to customize the hydraulic directional control cartridge valve, then I knew that he had purchased the hydraulic directional control cartridge valve from a cartridge valve manufacturer in Ningbo. During the equipment commissioning, the pile driver started slowly and had general stability. Their sales did not think that it was up to par. The engineer analyzed and suggested that the external control system should be connected or the high-frequency reversing function of the hydraulic directional control cartridge valve should be added. The boss asked to improve the hydraulic directional control cartridge valve, but the original hydraulic directional control cartridge valve manufacturer said that this is a standard part of HydraForce and cannot be improved. Laertes had to contact AAK cartridge valve again. According to his hydraulic schematic diagram, production drawings of hydraulic directional control cartridge valve and equipment working video, AAK engineers said that adding the high-frequency reversing function to the hydraulic directional control cartridge valve can indeed avoid the slow vibration of the equipment and improve the stability. The directional control of AAK is to control the valve spool through oil circuit switching, and realize the commutation frequency adjustment of the hydraulic directional control cartridge valve. Laertes paid the development fee on the second day. After 35 days, AAK sent 12 samples of hydraulic directional control cartridge valves. Yesterday, Laertes informed by email that after replacing with AAK hydraulic directional control cartridge valve, the pile driver was debugged smoothly, and the vibration of the pile driver was fast, the power density was high, the stability was good, and the high frequency and large flow could be met. The AAK optimized hydraulic directional control cartridge valve has one more function than the standard part of HydraForce. 1. The AAK hydraulic directional control cartridge valve body has multiple valve holes and multiple main oil passage ports, and the valve holes are interconnected. 2. Two throttle valve spools are installed on the control flow channel between the oil chambers on both sides of the main oil circuit switching valve spool and the control oil circuit switching valve spool. The flow area of the two throttle valve spools can be adjusted. The pressure reducing valve spool is installed on the control flow passage between the main oil passage port and the control oil passage switching valve spool. 3. There is a control oil passage port on the valve body for connecting the external control oil passage. The oil pressure area of the control oil chamber at both ends of the control oil switching valve spool and the main oil circuit switching valve spool is different. Under normal pressure, the oil pressure acting area of the oil chamber is smaller than that of the variable pressure oil chamber, which can realize the differential connection of the control oil circuit. By controlling the movement of the oil switching valve spool and the main oil circuit switching valve spool, the main oil circuit switching is realized. By adjusting the flow area of the two throttling valve spools, the oil resistance of the control oil chamber is changed, the movement speed of the main oil circuit switching valve spool is changed, and the reversing time is adjusted to realize the reversing frequency adjustment of the hydraulic directional control cartridge valve. AAK, a cartridge valve manufacturer in China, its hydraulic directional control cartridge valve has one more function than the standard parts of HydraForce.

Vladilen is from Russia. Recently, he was heartbroken by a hydraulic directional control valve that is to be used in chemical engineering and needs to be corrosion-resistant for over 1 year. AAK does not adhere to conventional material selection, replacing traditional carbon steel with stainless steel, and has skilled processing of stainless steel, achieving an accuracy of within 2μm, helping Vladilen received a big order finally. At the beginning of this year, a hydraulic system used in a chemical plant required a hydraulic directional control valve, and anti-corrosion for more than 1 year was a challenge. Vladilen asked more than 10 hydraulic directional control valve manufacturers, but none of them were not able to meet the requirement of chemical anti-corrosion for 1 year. Vladilen left a message on the AAK hydraulic valve website: Can AAK produce hydraulic directional control valves for use in chemical plants that are corrosion-resistant for more than 1 year? I told him that stainless steel needs to be used to replace traditional carbon steel in the production of valve bodies, but the difficulty of cutting stainless steel is high, the cutting temperature is high, and the tool life is short. Not only is efficiency low, but the surface accuracy of the valve cage is also a major obstacle. Most hydraulic valve manufacturers in China may consider using stainless steel to produce valve bodies, but they cannot master the processing efficiency and accuracy and have to give up. Our suggestion may have given Vladilen hope, he directly requested AAK to make samples. After 50 days, AAK sent out 30 samples of hydraulic directional control valves with stainless steel valve bodies. Last week, Vladilen placed his first order for 500 hydraulic directional control valves. Their engineers are very satisfied with the accuracy of AAK samples, especially the valve hole accuracy not exceeding 2μm. The better news is that AAK hydraulic directional control valves have been recognized by their testing and can withstand corrosion for more than 1 year. AAK hydraulic directional control valve used in chemical plants can be corrosion-resistant for more than 1 year, due to 3 advantages: 1. For the material selection, we dare to use the most difficult to cut stainless steel to produce valve bodies. This is the most solid barrier for corrosion prevention for more than 1 year. 2. The processing of stainless steel materials uses Baker reamers imported from Germany, made of high cobalt steel material, with sharp and smooth edges, smooth hole walls, and an accuracy of within 2μm. 3. Equipped with DC-507 semi synthetic cutting fluid, its special cooling performance easily reduces cutting heat, and its lubricity, permeability, and rust resistance are the most suitable for stainless steel cutting needs, while also protecting the tool. AAK hydraulic directional control valve, used in chemical plants and corrosion- resistant for more than 1 year, you can also try it out!

March comes from Brazil, and their power unit is used in a relatively niche market. The hydraulic cartridge valves used are mostly non-standard. They used to purchase from hydraulic cartridge valve manufacturers in Europe, and apart from being expensive and slow in time, everything else was fine. Recently, he has been trying to purchase from hydraulic cartridge valve manufacturers in China, and the customization time has been also slow. However, the quality and functionality of the Chinese hydraulic cartridge valve manufacturers he has chosen are more troubled than those in Europe, which makes March very upset. March left a message on the website of hydraulic cartridge valve manufacturer AAK: 1. Are you interested and capable of customizing non-standard hydraulic cartridge valves? 2. According to my drawings, what is the lead time for customized hydraulic cartridge valves? 3. Is there any guarantee for the stability of the hydraulic cartridge valve function? After email communication, we learned that when purchasing non-standard parts from Chinese hydraulic cartridge valve manufacturers, he encountered difficulties with the functionality of hydraulic cartridge valves. After several rounds of communication, March may have confidence in the hydraulic cartridge valve manufacturer AAK and sent us the drawings, as well as the samples from the original hydraulic cartridge valve manufacturer. Whether it is the contour size of hydraulic cartridge valves or the internal structure of hydraulic cartridge valves, they are very unpopular. Our technical department is not 100% confident either. In order not to waste March's time, I suggest that he customize at the same time with previous suppliers such as European hydraulic cartridge valve manufacturers and AAK. If AAK customization fails, the development fee will be refunded. 3 months later, after internal testing by AAK, non-standard parts were sent out. March seems not excited either. The samples from the original Chinese hydraulic cartridge valve manufacturer also took 3 months, but after 2 weeks of internal use, the function of the hydraulic cartridge valve became abnormal. 1 month after the sample was sent out, March sent us an email to advised that the samples customized by AAK has undergone internal testing for 1 month, which has basically been recognized by their engineers. Once their power unit is confirmed by the customer, AAK's hydraulic cartridge valve will truly pass the standard. I told March that based on our internal testing curve, I am not worried about the stability of the hydraulic cartridge valve function unless there is a change in external working conditions. The customized hydraulic cartridge valve of AAK uses a self-developed functional testing platform for functional testing. The customized hydraulic cartridge valve is installed into the simulated valve block inside the equipment, connected to the electromagnetic coil, and started to be tested after startup. The valve spool is automatically opened, and the hydraulic oil begins to work. Where it goes, the flow and pressure curves of the hydraulic cartridge valve will be displayed on the display screen of the equipment. After 3 seconds, the valve spool will automatically close, and the flow and pressure curves at the time of closure will also be generated synchronously. The obtained curve is very systematic and visually assesses the function of the hydraulic cartridge valve. Then, perform the same test again, but increase the working condition by 20%. Most Chinese hydraulic cartridge valve manufacturers rely on data and experience to judege the function. There may not be a dynamic curve in their testing. Even if there is, it may not perform every test twice. Yesterday, March sent us an email and their power unit was confirmed by the customer. They also received the customized samples from Europe, but they decided to choose AAK hydraulic cartridge valve, which is not only fast and stable in function, but also more than 30% cheaper than hydraulic cartridge valve manufacturers in Europe. For customized hydraulic cartridge valves, AAK may not be inferior to hydraulic cartridge valve manufacturers in Europe.

Katherine is from a Greek hydraulic equipment manufacturing company. There were several inquiries for hydraulic cartridge flow control valves with AAK before, but there was no cooperation. In the second half of last year, their customer wanted to customize a set of hydraulic power unit used in aviation equipment. The requirements for hydraulic cartridge flow control valve parameters were: performance of 2 million times, valve hole accuracy with 1μm, high pressure resistance 450bar. Seeing these strict parameter requirements, Katherine ware not sure if there is any hydraulic valve manufacturer who can meet it. More than 10 manufacturers of hydraulic cartridge flow control valves have been contacted, none of them was able to achieve it. Their engineer suggested Katherine contact German HAWE, because HAWE is the No 1 in the subdivision of high-pressure hydraulic valves. But HAWE had no time to sample. 2 weeks later, there was no progress. Katherine was worried. Her customer introduced a local manufacturer of hydraulic cartridge flow control valves in Greece, and Katherine also contacted me. According to above information, I told her directly that we are not sure for success, but our engineers are confident in the sample. 50 days later, Katherine's team tested the hydraulic cartridge flow control valves of Greek hydraulic valve manufacturer and AAK, both the results failed. The Greek manufacturer of hydraulic cartridge flow control valve gave up making samples for the second time. Katherine hoped that AAK can make samples for the second time. Although some parameters of AAK hydraulic cartridge flow control valve did not meet the standard, the overall quality was stronger than that of the Greek hydraulic valve manufacturer, and was close to the parameter requirements. I told him that such a demanding sample, like an exam, is not difficult to improve from 80 points to 99 points, but it is a great challenge to improve from 99 points to 100 points. Katherine understood the situation. I suggest that she postpone the development with the customer first, and I will update any information about AAK samples in a timely manner. After 6 months, AAK sent 10 hydraulic cartridge flow control valves. During this period, AAK technical team experienced 3 material changes, 6 samples, 12 inspections, and 180 days of challenges, and achieved the success. 2 months after the hydraulic cartridge flow control valves were sent, Katherine emailed us to express her surprise and thanks. It turned out that Katherine thought AAK had given up the sample long ago. Unexpectedly, she received the samples of hydraulic cartridge flow control valves 180 days later, and the parameters were all qualified. This test sample challenged the soft power of AAK and the ingenious strength of the technical team, and failed repeatedly until success. 1. In terms of material selection, Japan SCM415 alloy steel was finally tested to be the most suitable one. After we have improved the heat treatment process for a long time, the hardness reaches HRC65, the wear resistance and strength are more than 3-5 times that of other steels, and there is no wear for more than 2 million times. 2. In processing, the honing rod is customized on the American precision honing machine, and is equipped with diamond oilstone to replace the diamond reamer, then it is easy for the valve hole accuracy with 0.8μm. It is hard for peers to think of such operation in the processing technology link. 3. In terms of testing, the high pressure test bench and durability testing equipment independently developed by AAK is used, the pressure, flow and fatigue resistance of the valve, are 100% fully inspected. Katherine told us privately that their engineers, his boss and their customer were all impressed by AAK. AAK hydraulic cartridge flow control valve, never give up after failure, you can also have a try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-flow-control- valves-aak3 , 79

Sofronio, from Brazil, has been engaged in the procurement of hydraulic valves for 3 years, and has been successful, but stumbled in purchasing hydraulic manifolds. Last year, they wanted to promote a high pressure hydraulic roller, requiring the entire hydraulic manifold to be able to withstand high pressure of 450Bar. A local hydraulic valve manufacturer promised to provide design, sample and one-stop service for Sofronio according to equipment working conditions. The equipment debugging was also smooth. After being put into the market, the sales of hydraulic rollers is just so so, the user feedback equipment functions are just so so, and the energy consumption is high. Their engineer suggested that the hydraulic manifold should be improved, and the high pressure should be sustained, and the hydraulic manifold oil circuit should be simplified. However, the original manufacturer could not able to meet it, and suggested that Sofronio find a supplier of German HAWE. A week later, it was fruitless. Sofronio has found in Google that AAK has hydraulic valves benchmarking HAWE, and resistant to high pressure of 450Bar. He left a message: can you design, sample and produce the hydraulic manifold with high pressure resistance of 450Bar, and control the energy consumption well? I told him that as long as the hydraulic screw-in cartridge valves selected for hydraulic manifold can withstand 450Bar of high pressure, and the oil circuit design meets 450Bar of high pressure, the pain point will be solved. Sofronio emailed me the photos of the hydraulic manifolds produced by Brazilian manufacturer and the working conditions of the hydraulic roller. AAK engineer found the hidden danger in the original hydraulic manifold design at a glance and suggested him to directly try AAK samples. It seems that Sofronio does not believe that AAK can do a good job and he is hesitant. I can understand that it is stuck here. Our engineer was flexible. He draw a hydraulic manifold sketch, marked the configuration of each valve, and highlighted the oil circuit layout. The day after Sofronio got the hydraulic manifold sketch, he paid the development cost and specifically emphasized that this is just what their engineer required. Maybe the engineers on both sides have a mind consonance. 1 month later, AAK sent 5 sets of hydraulic manifolds. 5 weeks later, Sofronio informed that with AAK hydraulic manifolds, the hydraulic roller is powerful, its functions can meet the original users, and its energy consumption is reduced. Their sales team is confident of a turnaround. Last week, Sofronio ordered 260 sets of hydraulic manifolds. Because the promotion of the new hydraulic roller was smooth, the reservation was doubled several times. AAK can replace Brazilian hydraulic valve manufacturer because AAK has 3 advantages. 1. AAK has full-time engineer to select the material and cartridge valves for the hydraulic manifold, who is specially responsible for material screening, comparison, testing, and interfacing with the research institute. Match the appropriate materials and hydraulic components according to the working conditions of the equipment, instead of those commonly used in the market. 2. AAK has engineer who has worked at HAWE for 11 years, has a mind in the hydraulic manifold design, insists on the flow distribution on demand, and eliminates bypass. The oil circuit control is sensitive and easy to control, which is not only low in energy consumption but also high in efficiency. 3. MDTools software is used, from the loop logic to the functionality of each valve, can be personalized designed, reducing the number of couplings, pipelines and hoses installed, without the use of fixtures, which is not only low energy consumption, but also high efficiency. AAK hydraulic manifold, high pressure resistant 450Bar, and low energy consumption, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak378

Payne is from a hydraulic equipment company in the United States. His purchase process has been smooth for 3 years. He did not have much cooperation with AAK, until the purchase of a hydraulic pressure control cartridge valve suffered a loss elsewhere, he trusts AAK more and more. 2 years ago, their company sold tunnel boring machines. Less than half a year after sales, customers complained that the equipment was on strike. The after sales worker found that the contact surface between the hydraulic pressure control cartridge valve spool and the valve cage of the hydraulic system of the equipment had signs of wear. It was judged that the leakage led to insufficient pressure supply for the system, and they went on strike. The original manufacturer of the hydraulic pressure control cartridge valve pushed the buck. He thought that the system pressure of the hydraulic tunnel boring machine was more than 450bar, and the opening and closing frequency of the hydraulic pressure control cartridge valve was high. After half a year of use, it was normal that the valve cage was worn, so only solution was to replace the hydraulic pressure control cartridge valves with new ones. 6 months later after replacement, the same problem occurred again. Payne realized that the hydraulic pressure control cartridge valve of the original manufacturer has a service life of only 6 months. The boss was not satisfied with the after-sales service of the original manufacturer, and asked Payne to re purchase the hydraulic pressure control cartridge valves with a service life of at least 18 months. 2 weeks passed, the no manufacturer was willing to accept the order. Payne was worried. Payne emailed me and asked how long AAK can guarantee the service life of the hydraulic pressure control cartridge valve under the working condition of 450bar high pressure and high frequency use? After knowing Payne's dilemma in purchasing the hydraulic pressure control cartridge valves, I told him that most hydraulic valve manufacturers would replace the valves in about 6 months under high-frequency and high-pressure working conditions. Only HAWE hydraulic pressure control cartridge valve can have a service life of 2 million times, which is more than 2 years. The manufacturing quality of AAK hydraulic pressure control cartridge valve is the benchmark of HAWE. After 30 days, AAK sent 12 samples of hydraulic pressure control cartridge valves. 3 weeks later, Payne informed AAK that the hydraulic pressure control cartridge valve was approved for function and the performance was waiting for test. Last month, Payne informed by email that it had been more than a year since AAK hydraulic pressure control cartridge valve was installed, and there was no strike complaint about the equipment. His boss was very satisfied with this batch of purchase. For the hydraulic pressure control cartridge valve under high frequency use and high pressure conditions, AAK benchmarking HAWE, focused on 3 points, most hydraulic valve manufacturers can not reach. 1. Material selection is the key. AAK uses SCM415 alloy steel from Japan, which has mechanical properties more than 70% stronger than similar materials. After carburizing and heat treatment, the hardness of the valve body is higher than HRC65, and the wear resistance is more than 3 times of the general 45 steel. Most hydraulic valve manufacturers want to use this material, but they are not sufficient on heat treatment, so they have to give up. 2. The inspection is also important. AAK has independently developed hydraulic valve durability testing equipment. In combination with NFPA/T2.6.1 standard, it conducts fatigue testing on materials and 100% full inspection. 3. Technical skill is the basis. AAK has shipped the hydraulic cartridge valves under 450bar high pressure and high frequency use conditions for many times. AAK do not only the engineer who have worked in HAWE for 7 years, but also the old technicians who have worked for more than 30 years. AAK hydraulic pressure control cartridge valve has a performance of 2 million times under high frequency use and high pressure conditions. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-control-cartridge- valves- , aak377

Last weekend, when I talked about the values of AAK hydraulic manifolds, unexpectedly, a customer left a message: our ideas are the same. Let me report the mission, vision and values of AAK hydraulic manifolds. 2022 seems to be an uncertain year. When everything becomes uncertain, the only certainty is the belief in the future, relying on the mission, vision and values. We often say that because we believe, we see. What is a vision? Vision is a picture of a better future. For example, what changes may happen to the hydraulic industry due to the existence of AAK hydraulic manifolds. The vision of AAK hydraulic manifolds: right installation at one time, successful trial run at one time, and energy consumption reduction of more than 5%. When AAK hydraulic manifolds started its business, it was full of passion, like a perpetual motion machine. After encountered more difficulties later, we also felt tired or powerless. 2 days before Christmas in 2014, our hydraulic manifold samples were not recognized for two times, and Steven canceled the hydraulic manifold order of 620,000 dollars. We spent more than 20,000 dollars and more than 2 months on these samples. The technical team didn't have weekends or rest days, and they went off work after 9 o'clock every night. As a result, all returned to zero. The weather was extremely cold that day, and the morale of the whole team was gone. I was the only one in the office. The air was chilly. Outside the window was a cold wind, whizzing. The wind was beating the branches. Several dead leaves were rolled up and swung in the air. After a while, they disappeared like ghosts. The next day, I came to the office without breakfast. Because I can't give up, I have to be responsible for my employees. In my mind, I have a vision of the future inspiring me, and also attracting my team to work together. I don't want the whole team to be kidnapped by the "sense of responsibility", but motivated by the vision and mission. I think this is also the role of AAK's vision of hydraulic manifolds: "correct installation at one time, successful trial run at one time, and energy consumption reduction of more than 5%". Why did AAK hydraulic manifolds start? Only with the meaning of vision can we attract people with the same frequency, and our ideas can change from "I fight for you" to "we fight side by side for the common vision". There is no value if only vision. For AAK, I still need to know what to do to realize this vision. What the mission of AAK hydraulic manifolds is, what our career is, or what role we play on the way to realize the vision of AAK hydraulic manifolds. AAK's hydraulic manifold mission (R&D and manufacturing, which is sufficient to benchmark the hydraulic manifolds quality of the international first-line brands) is on the way at this time. Maybe you don't understand the mission and vision very well. Vision is what customers expect of you. Mission, what do you do and to what extent? Take an example to explain mission, in literary novels, the protagonist and villaiin are on a par in martial arts, and even the villaiin has a higher value in force. The protagonist defeats repeatedly, but finally defeats the villaiin. Why? Because the protagonist has a certain mission, such as punishing the evil and promoting the good. Because of the mission, difficulties are the strength to persevere. How does the main character do it? For example, in the first stage, they should become stronger, go to the mountain to learn martial arts. The second stage is to go down the mountain to find opportunities and start the journey of heroes. The third stage is to form a team and start a group war to destroy the rebels. Finally, the Martial Arts World returns to justice. With vision and mission. how can we ensure that there is no deviation? The mission of AAK hydraulic manifolds is: R&D and manufacturing, which is sufficient to benchmark the hydraulic manifolds quality of the international first-line brands. Stable quality requires good materials. In the first half of this year, the steel material cost fluctuates greatly. Can we temporarily use substitute materials and resume using genuine materials when the steel material cost is stable? At this time, values are required to constrain. Absolutely not. Once this is done, it means violating the values. What values? Values, I usually understand it as the ethics of the enterprise, that is, what is your standard for being a person and doing business? The commitments of AAK hydraulic manifolds in these 3 aspects are: Behaviour: (1 zero, 3 no), zero small action, so that customers do not take detours, do not step on the pit, do not spend money wrongly. Work: Respond to customers with efficiency and screen people with efficiency. To be an enterprise: for a customer's question, give 3 altruistic alternatives. We say that when the situation is unclear, the facts are unclear, and there is no data and logic support, people often listen to their inner voice to make decisions. This inner voice is human values. For enterprises, the existence of values is to help them make the right decisions and uphold corporate ethics when facing difficult decisions. For example, what should be done, what must be done, and what should not be done even if it can earn a lot of money. Enterprises face financial and profit pressures. If you want to solve this problem, you have to violate social responsibility. Do you continue to adhere to social responsibility or give up? For example, an enterprise must not do something. Once it conflicts with making money, it will choose this thing instead of making money. If a hydraulic manifold manufacturer does not have a mission, vision, or long- term development values, the big probability is that it will just take orders and join in the fun when there are openings. If there is no profit, it will cut corners. It is difficult to insist on do something and not do something. The vision of AAK hydraulic manifold: right installation at one time, successful trial run at one time, and energy consumption reduction of more than 5%. AAK hydraulic manifold mission: R&D and manufacturing, which is sufficient to benchmark the hydraulic manifold quality of the international first-line brands. AAK Hydraulic manifolds Values: Being a man: no small action, so that customers do not take detours, do not step on the pit, do not spend money wrongly. Work: Respond to customers with efficiency and screen people with efficiency. To be an enterprise: for a customer's question, give 3 altruistic alternatives. AAK hydraulic manifolds, do something, and also never do something. https://www.aakindustry.com/info , -detail/hydraulic-manifolds-aak437

Edgar is from a hydraulic company in Britain and has been engaged in procurement for 2 years. Recently, the supervisor asked him to purchase a hydraulic cartridge flow control valve with a rated pressure of 15~20MPa, a fit clearance of 0.012~0.015mm and a cylindricity of 0.003mm. The supervisor specially emphasized that this was the project the boss was looking at. Edgar saw the parameters of this hydraulic cartridge flow control valve and was a bit stunned. It was difficult for his current hydraulic cartridge flow control valve manufacturers to reach the standard. Although one of the manufacturers promised to be 90% sure, the cylindricity accuracy could not be approved, because the processing of the blind hole of the hydraulic cartridge flow control valve was not sufficient enough. He failed to meet the standard even after 3 adjustments. More than a month has passed, and no progress has been made. Edgar was very worried. I'm not sure where Edgar learned about AAK. He left a message on our website: Can you process the hydraulic cartridge flow control valve with a cylindricity of 0.003mm? Because the parameters are not the only factor, we cannot simply answer yes or no. I can only tell him that the problem of the original hydraulic cartridge flow control valve manufacturer lies in the tool, and most hydraulic valve manufacturers still use traditional diamond reamers. This technology is not only highly demanding for technicians, but the tool is also easy to wear. In diamond reamer cutting, the force is mainly concentrated on the tool head, and the head wears quickly. This makes the hole bottom size smaller and affects the cylindricity of the valve hole. Edgar should have felt that AAK pointed to the point, so he sent us the complete drawing of the hydraulic cartridge flow control valve, informing us of the above procurement difficulties, hoping that AAK could help him with solution. According to Edgar's drawings, I told him that AAK should make samples directly. If it is not successful, the development cost will be returned. After 30 days, 6 hydraulic cartridge flow control valve samples were sent out. 3 weeks later, Edgar sent a PO for hydraulic cartridge flow control valve worth 20,000 US dollars. At the same time, he advised that their engineers were very satisfied with AAK samples and required that the manufacturing quality of mass production must be the same as the samples. I told him that the shipment will be the same as the samples, it was more difficult for the workshop to do a little worse than to do a little better. Edgar was curious about what technology AAK used to solve the cylindricity problem of the hydraulic cartridge flow control valve. 3 years ago, AAK realized that the cylindricity of the valve hole would have hidden problem due to the traditional diamond reamer processing technology, so we replaced it with new honing machine, and the the diamond reamer was replaced by diamond oilstone, which is installed on the special honing rod. The oilstone can expand and shrink radially, gradually cut off the allowance of the valve hole, and is equipped with an automatic measuring system. After rough honing, the diameter of the valve hole can be measured 360 degrees. If the size is abnormal, the oilstone will correct it. In this way, the cylindricity of the machined valve hole can reach 0.0025~0.003mm, moreover, the surface roughness is Ra0.2. Last week, Edgar told me privately that his boss paid more and more attention to him after the smooth delivery of this hydraulic cartridge flow control valve. AAK hydraulic cartridge flow control valve, cylindricity within 0.003mm, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-flow-control- valves-aak3 , 76

Today, AAK would like to introduce a hydraulic cartridge flow control valve E-FC10-21, benchmark HydraForce FC10-21. It is a screw-in, cartridge style, variable orifice, hydraulic flow control valve with reverse flow check. The E-FC10-21 valve increases its orifice value from fully closed to fully open with clockwise adjustment rotation. Many hydraulic cartridge valve manufacturers in Ningbo China do not have this model. One of our customers in Turkey checked with 7 hydraulic cartridge valve manufacturers in Ningbo China within 1 month, but none of them have this cartridge flow control valve. He was very happily to find it from AAK hydraulic valve website finally via google, and the manufacturing quality and performance is equivalent to HydraForce FC10-21. The selling points of this hydraulic cartridge flow control valve are: 1. Benchmarking HydraForce FC10-21 2. Its service life is 2 times that of its peers Technical parameters of AAK E-FC10-21 HYDRAULIC CARTRIDGE FLOW CONTROL VALVE: Working Pressure: 240 bar (3500 psi) Flow Rating: 57 lpm (15 gpm) At fully open (2 turns) 5.5 bar (80 psi) Internal Leakage: 0.50 ml/min (10 drops/min) Max. at shut off Operating torque required: 0.34 Nm (3 in-lb) At 7 bar (100 psi) 4.5 Nm (40 in-lb) At 207 bar (3000 psi) Temperature Range: -40°C ~ +120 °C (with Buna N seals) Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties Fluid viscosity range: 7.4 to 420 cSt (50 to 2000 ssu) Cavity: VC10-2A For this screw-in, cartridge style, variable orifice, hydraulic flow control valve with reverse flow check, its quality is benchmarking HydraForce FC10- 21, you can try it out!

Giles is from Greece, and has been successful in purchasing hydraulic valves from China, but recently he was greatly affected by a hydraulic directional control valve. In the second half of 2021, their paper cutting machine needed the use of hydraulic directional control valves. Giles purchased it from a hydraulic directional control valve manufacturer in Ningbo China. Half a year later, a customer complained that the hydraulic directional control valve was leaking and causing abnormalities in the paper cutting machine. The original hydraulic directional control valve manufacturer stated that its service life was over and could only be replaced with new ones. Giles was helpless and had to search for a new manufacturer of hydraulic directional control valves with a service life of more than 2 million times. After a week, there was no result. Giles sent an email to AAK and the first sentence is like this: he was surprised by AAK's ranking on Google and on the homepage of China hydraulic valve manufacturers. I understood that he found the AAK hydraulic valves on Google. After communication, it was learned that Giles needs hydraulic directional control valves with a service life of over 2 million times. I provided two customer cases for his reference. No correct nonsense, only existing facts that AAK is far ahead of its peers, the other hydraulic cartridge valve manufacturers in China. Facts are power. Giles requested AAK samples on the third day. After 55 days, AAK sent 30 samples of hydraulic directional control valves. Last week, Giles sent us a PO for 1,000 hydraulic directional control valves. Their technical department has tested the hydraulic directional control valve samples of AAK for 1 year, and there are no leaks. AAK hydraulic directional control valve samples have met the requirement of a service life of more than 2 million times, and he now only believes in AAK. In fact, achieving a hydraulic directional control valve with a service life of over 2 million times is not difficult. AAK adopts a 2+1 mode, first passing through 2 steps, and finally batch testing the service life of the hydraulic directional control valves. 1. Increase the procurement cost of materials and accessories by more than 15% to ensure that the materials pass their lifespan first. 2. Increase processing costs by more than 10%, increase the number of quality inspectors for key processes, assign responsibilities to individuals, and ensure that functions pass the lifespan first. AAK hydraulic directional control valves are also tested for a service life of more than 2 million times, to ensure that its performance exceeds its lifespan. AAK has independently developed durability testing equipment that complies with the NFPA/T2.6.1 standard and performs fatigue testing on valves. AAK's durability testing equipment has 5 testing stations that can operate independently of each other, and each testing area is equipped with hydraulic and electrical sources that help with valve fatigue testing. The testing efficiency has been improved by more than 60% compared to peers. AAK hydraulic directional control valve, with a service life of over 2 million times, you can also give it a try!

Esmaeel is from Iran. He is an interesting friend. If he doesn't have an order, he won't come to me, unless when he was in trouble. In the second half of last year, Esmaeel asked me to customize a hydraulic flow control cartridge valve as soon as possible. After communication, we learned that the test of their hydraulic pile driver was not smooth and the response was very slow. Their engineer judged that the hydraulic flow control cartridge valve was not awesome, which was customized by a hydraulic cartridge valve manufacturer in India. The manufacturer said that the system flow was too large, resulting in the slow response of the hydraulic flow control cartridge valve. The engineer was not satisfied with the original manufacturer and asked to replace the supplier. I asked him why he didn't contact AAK to customize this hydraulic flow control cartridge valve at the beginning. Esmaeel explained that this Indian cartridge valve manufacturer was designated by his customer, because this factory has ready-made procedures, which greatly shortened the development time. According to his hydraulic system schematic diagram and the original hydraulic flow control cartridge valve drawing, after internal discussion, I told him that the functions of the hydraulic flow control cartridge valve from this Indian cartridge valve manufacturer are not suitable for their equipment and it must be innovated. If AAK plan works out smoothly, we can finish samples within 45 days. 2 weeks after sending the sample of hydraulic flow control cartridge valve, Esmaeel told me that the pile driver test was successful, and let me wait for his good news. Today, I received the PO for 160 hydraulic flow control cartridge valves, and can't wait to share the innovative functions of our hydraulic flow control cartridge valves with you. AAK hydraulic flow control cartridge valve can realize large flow connection and fast response, here is what we do. 1. The valve spool and sleeve of the hydraulic flow control cartridge valve are of three-section type. The outer wall of each section of the valve spool is processed with convex steps. The cross-sectional area of the inner cavity of the three-section valve sleeve increases in turn. The axial through-hole of the valve sleeve penetrates from the lower end to the upper end. Each section of valve sleeve is provided with a plurality of radial oil ports, which are connected with the oil passage cavity. 2. The valve spool is sleeved in the axial through-hole of the valve sleeve, and the valve spool guide is arranged in the guide cavity. The valve sleeve is located in the control cover plate, which has 3 oil passages. One end of the return spring is connected with the control cover plate, the other end is connected with the second spool, and the oil passage cavity is connected with the return spring cavity. 3. There are 3 seals in the guide sleeve of the valve spool, and there is no leakage in the cavity. The optimized hydraulic flow control cartridge valve has 2 function positions. The flow capacity of the first function position is less than the flow capacity of the second function position. The two-way pressure control is adopted, and the response speed is fast. The hydraulic flow control cartridge valve can be controlled with less pressure oil. The flow difference in the system does not affect the response of the hydraulic flow control cartridge valve.    AAK hydraulic flow control cartridge valve, even if the flow is large, the response speed is still fast, you can also try it! https://www.aakindustry.com/info-detail , /flow-control-cartridge-valves-aak509

Krischnan is from a hydraulic equipment manufacturing company in the United States. He has been engaged in hydraulic manifold procurement for only 1 year. In the second half of last year, they developed a hydraulic oil pump to promote for new. The hydraulic manifold used comes from the design of their engineers. They chose a hydraulic manifold manufacturer who has worked with them for 5 years to try samples. 2 months later, the commissioning was not smooth. After the equipment was started for a period of time, the pressure supply of the oil pump was unstable, resulting in high energy consumption of the equipment, which had no advantage over the peers. The boss asked that the problem be solved within 3 months. The engineer asked Krischnan to contact the original hydraulic manifold manufacturer to solve the problem, but the manufacturer only had production capacity and can not offer solution. Krischnan was worried that the technical department blamed the purchase for the abnormal test run and had to check with many hydraulic manifold manufacturers. 1 week later, only one hydraulic manifold manufacturer replied that the manifold might need to be redesigned, but he was not sure. Krischnan was worried about time being wasted day by day. When browsing Google, Krischnan found an article of AAK about hydraulic manifolds and asked by email: Can you improve the hydraulic manifold design and make samples according to the working conditions of the equipment? I felt that he may have encountered problems on making samples for hydraulic manifolds. After communication, I learned that there was also a problem with the hydraulic manifold design. According to his hydraulic manifold drawings, as well as the condition of equipment commissioning, I told him that AAK was 80% sure to redesign the hydraulic manifold and sample it. If successful, it can help reduce the energy consumption of the equipment by 20%. Krischnan was happy but also worried when he learned that, but he seemed to have no choice but to bet on AAK's success. After 50 days, 5 redesigned hydraulic manifold samples were delivered. 4 weeks after the hydraulic manifold was sent out, Krischnan told us that the test run was smooth, the pressure supply of the oil pump was stable, and the energy consumption also decreased by more than 20%. The entire technical team was very happy and sure that it would be recognized by the market soon. The improvement of this hydraulic manifold is the reverse thinking operation, from "why the pressure supply is unstable" to the oil circuit and oil hole. AAK did this way: composed of relief valve, hydraulic time-delay valve and check valve. The sparkle is that there are oil inlet, oil return and oil outlet holes in the valve body. Each oil hole is connected to two cartridge valves, and the control oil holes of the hydraulic time-delay valve and the relief valve are connected to the corresponding oil holes in the valve body. The setting of another cartridge valve can make the pump have the function of one-way oil supply. The whole hydraulic manifold structure is compact, reducing pipes, joints and pipe fittings, simplifying the installation project, and replacing pipes with oil holes, which is also helpful for energy consumption. A few days ago, Krischnan told me privately that AAK's design idea was admired by their engineers. Now, people in the technical team respect him more when they see him, and what he does is more and more interesting. AAK hydraulic manifold, reduces energy consumption by 20%, and you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak375

China is now the second largest economy in the world, but some people begin to worry that China can not keep the second place, because in recent years, some manufacturing industries have been moved to Southeast Asia, which will affect China's GDP. Normal anxiety and pessimism are understandable, but they are useless. The more uncertain it is, the more sincerity and integrity are needed. China's hydraulic valve manufacturers with lots of blue-collar technicians are unlikely to be replaced by hydraulic valve manufacturers in Southeast Asian countries even after another 30 years. We are optimistic that the future of Chinese hydraulic valve manufacturers depends on how many blue-collar operators you have.   A country's industrial index is endorsed by factories with technical content, which requires Chinese hydraulic valve manufacturers to introduce or cultivate more blue-collar technicians, which is the confidence of the future. The goal of AAK Hydraulic Valve is that every operator should have a unique skill. Yesterday's achievements are not the end, and AAK Hydraulic Valve will never stop. The vast majority of technical blue collar workers do not compromise on quality. Even if the cost is 2-3 times higher, they should choose the best solution. Even if it's 2-3 times more expensive, choose the best one. Because it is not good enough, I cannot do it and give it to consumers. From the perspective of products as works, do you still worry about inferior products from operators with such mentality? AAK Hydraulic Valve can never say let it go. Once the scheme is determined, the sample shall be taken out. How do you do it? The devil of products is always in the details. The details are all questions that need attention.   Sincerity and integrity, we should be full of enthusiasm first, so as to better face the future. Success is not necessarily more fortunate than others, but more failures than others. If you fail, go through it. At the same time, do self-examination on your own process, technology, quality, service, and make improvements.   Sincerity and integrity also need to love life. As long as you love life, your anxiety and weakness will heal. You will have passion to write tweets, take videos of hydraulic valves and promote products.   Sincerity and integrity, we need to treat our partners with heart, produce hydraulic valves with sincerity and integrity, and serve users with sincerity and integrity. Sincerely face work and life, and face the future.   To serve customers sincerely, first of all, we should try our best to keep the real state, because we need to establish a long-term relationship with each other. It is the same logic to communicate with customers as go on blind dates. What should be the status of blind date? To be clean, wash your hair, wear a nice dress, and paint a light makeup. Because your purpose is to establish a long-term relationship with the other party, and it is to get married. Then you should try to keep your true state. If the other party appreciates the true you, you can build a long-term trust. If you create a false personal setting for yourself, and the other party is moved by the false personal setting, you spend 1 year and 2 years to get to know each other deeply, and find that it is completely different from what you knew at the beginning. If you break up again, it will cost a lot. If you hurt the other party, you also hurt yourself. Therefore, in my opinion, the promotion of hydraulic valves does not require public persona, because sincerity is the best way to lead to trust.   Sincerity is the best way to trust. The inquiry sent to you by the customer is actually a pre-sale trust to establish a long-term trust relationship. If you need to sell hydraulic valves, build trust by meeting, drinking with each other, playing ball, etc., that means your sweat on the hydraulic valves is not enough. Now, online can continuously reach customers, continuously provide value, and slowly build trust. The other party thinks you are reliable, which means you have pre-sale trust. Then, based on the trust in you, he will review your products. There is a time lag between the time when customers get to know you and the time when they buy. The purpose of AAK Hydraulic Valve promotion is to find ways to shorten this time difference. How to shorten it? There is logic behind this, which is pre-sale trust. The premise of pre-sale trust is sincerity. Only sincerity can establish a long-term trust relationship. AAK Hydraulic Valve, build relationship with sincerity and integrity. https://www.aakindustry.com/info-detail/ch , inese-hydraulic-valve-manufacturers- aak374

Tancredo comes from Italy, and he is an old hand in purchasing hydraulic manifolds. There are few hydraulic manifolds in cooperation with AAK. In the middle of last year, the first batch of hydraulic power units sold by their company, were complained of insufficient pressure supply and shock vibration 6 months after sales. During after sales service, it was found that the hydraulic cartridge valve of the hydraulic manifold was stuck, and the diameter of the intersecting hole of the valve block of the hydraulic manifold has deviation. The hydraulic manifold manufacturer advised that the residual burrs led to stuck, which may not be a large proportion. The hydraulic cartridge valves can be replaced for free, but he did not give reply about the diameter deviation at all. This after-sales service of hydraulic manifold is time-consuming and expensive. Tancredo realized that it was wrong to switch to this hydraulic manifold manufacturer, and was severely criticized by his boss. Before ordering this hydraulic manifold, Tancredo contacted more than 10 hydraulic manifold manufacturers successively, and I also received his inquiry, but I was told that AAK hydraulic manifold had no advantage in price, so he gave the order to another manufacturer. After the customer complained, Tancredo came to me again and complained that the selected hydraulic manifold manufacturer was unreliable. I told him that for the production of hydraulic manifold, more attention needs to be paid to the details of manufacturing quality. The manufacturers who can produce hydraulic cartridge valves very well, may not be able to produce hydraulic manifolds well. Tancredo did not dare to try other hydraulic manifold manufacturers, and asked AAK to try 30 samples of the hydraulic manifold. 6 months later, he tried another 30 hydraulic manifolds. I understand Tancredo's operation. He is scared to fail again, and can not face his boss. Last week, Tancredo told us that their engineers approved both batches of hydraulic manifold samples of AAK. The equipment installed with AAK hydraulic manifolds has been used for almost a year, and have no complaints. Why AAK hydraulic manifold can achieve reliable functions and guaranteed performance? It lies in 3 details of manufacturing quality: 1. The processing of hydraulic manifold block can ensure that the parallelism of two corresponding surfaces is less than 0.03mm, and the non perpendicularity of two adjacent surfaces is less than 0.05mm. The intersected drilling holes are designed according to the oil flow direction, and do not follow the trend to avoid eddy current or shock vibration. 2. Strictly control the treatment, deburring, rust removal, deoxidized skin removal, and cleaning of sharp edges of the hydraulic manifolds. Do not use traditional manual work. 3. Hydraulic manifold inspection, involves pressure test, function test, and is 100% fully inspected. AAK hydraulic manifold, 3 details of manufacturing quality, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak373
