Galeno, from Spain, has cooperated with AAK for 2 years and tried several non- standard customized hydraulic cartridge pressure control valves. At the beginning of this year, they developed a hydraulic windlass to be promoted in the exhibition. They need a hydraulic cartridge pressure control valve for the hydraulic system of the windlass. Galeno got samples from local manufacturer of hydraulic cartridge pressure control valves. After the commissioning, the pressure control of the equipment is unstable. The engineer judged that the cavity of the hydraulic manifold was off center, resulting in unstable pressure control of the hydraulic cartridge pressure control valve after being screwed in. The hydraulic manifold manufacturer needed 2 months to re sample, but the exhibition was less than 50 days, Galeno was worried. Galeno tried to find a new hydraulic manifold manufacturer. When I received his inquiry for hydraulic manifold, I was a bit surprise. After communication, I learned that he encountered unstable pressure control of hydraulic cartridge pressure control valve. I told him that under similar circumstances, it is not necessary to re produce the hydraulic manifold. 1 year ago, AAK developed a specially designed hydraulic cartridge pressure control valve, which was specially designed to coordinate with the off center cavity of the hydraulic manifold. Galeno compared the technical parameters of the AAK hydraulic cartridge pressure control valve and it basically matched the hydraulic system of their hydraulic windlass. 2 weeks after the sample was sent, Galeno informed that the installation of AAK hydraulic cartridge pressure control valve to the equipment was smooth, and the machine test was normal. The prototype was already on the way to the exhibition. His boss was very satisfied with this urgent solution. I told him that the unique design of AAK hydraulic cartridge pressure control valve was beyond the imagination of most hydraulic valve manufacturers. We got inspiration from an old customer. The customer purchased the hydraulic manifold block and the hydraulic cartridge pressure control valve from 2 different factories. After the installation was abnormal, the two factories passed the buck. At that time, we imagined whether it was possible to let the hydraulic cartridge pressure control valve match the hydraulic manifold block with off center cavity, or vice versa. AAK technical team has figured out that the middle thread can be used in the hydraulic cartridge pressure control valve, that is, the floating structure. The connection area of the port can be optimized, and the center of the thread position can be positioned to maximize the flow capacity and minimize the eccentric influence of the hydraulic manifold block cavity. The diameter of the valve shoulder at the thread provides guidance to ensure the accurate alignment of the thread. The space of the valve shoulder is sufficient, which increases the flexibility of the installation torque and is not easy to damage the torque. The installation torque space can minimize the impact of hydraulic pressure on the valve and is conducive to pressure control. AAK hydraulic cartridge pressure control valve, specially designed to match the hydraulic manifold block with off center cavity, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-pressure-control- valves- , aak363

Bemus is from a hydraulic equipment manufacturing company in Greece. As an old purchaser, he has been working smoothly, but had trouble with a hydraulic directional control cartridge valve. In the second half of last year, they wanted to test a hydraulic power unit for drilling equipment. The shaking was serious during the equipment commissioning, which was caused by the sudden impact of the hydraulic directional control cartridge valve under the high- pressure closed circuit. The original hydraulic directional control cartridge valve manufacturer explained that the hydraulic system pressure was too high. Their engineers asked Bemus to re-purchase the hydraulic directional control cartridge valves. After a week, there was no result. Bemus was worried. Bemus found AAK in B2B and left a message on our website: How to make the hydraulic directional control cartridge valve without impact under the high- pressure closed circuit? After several rounds of communication, we learned the above problem that he encountered in purchasing of the hydraulic directional control cartridge valves. According to the video of equipment abnormality and the production drawing of hydraulic directional control cartridge valve sent by him, AAK engineer was 90% confident to eliminate the abnormality caused by the impact force. Bemus requested AAK to make samples. After 50 days, AAK sent 12 samples of hydraulic directional control cartridge valves. 6 weeks later, Bemus said that the trial run of their equipment was successful and the prototype had been delivered to the customer. AAK hydraulic directional control cartridge valve, based on the unloading valve spool, made 3 small changes to achieve pressure release. The optimized hydraulic directional control cartridge valve reduces the oil pressure in the high-pressure closed circuit and avoids sudden impact. Its stability can better control the equipment operation. 1. The unloading valve spool is arranged in the valve spool, and the control piston is connected with the push rod. The control piston can open the valve spool, and the inlet and outlet are connected, thus realizing reverse flow. 2. The unloading valve spool is connected with the spring seat, one end of the spring is fixedly connected with the top of the valve body, and the other point is connected with the spring seat. When there is no pressure oil in the control oil port, the pressure oil can only flow from the passage port to the outlet, and cannot reverse flow. 3. The bottom of the unloading valve spool is processed into a "convex" shape, which plays the purpose of unloading before the valve spool. When the pressure at the outlet is high, the control piston pushes the unloading valve spool first. When the pressure at the outlet decreases, the unloading valve spool connects the inlet and outlet. AAK hydraulic directional control cartridge valve, no impact force, and stable, you can also try it! https://www.aakindustry.com/info-detail , /directional-control-cartridge-valves- aak506

The supplier who has cooperated for 3 years has failed to test the hydraulic cartridge flow control valve for 3 times. After AAK took over, the accuracy requirements were met at one time for the sample. The surface roughness of the inner hole of the hydraulic cartridge flow control valve was 0.15, and the cylindricity error was controlled within Φ0.003mm, the operating efficiency of the hydraulic system was also improved from 5% to 10%. Brand finally came to the sunny day from the rainy day for more than 30 days. Brand is from Brazil. In March this year, he sent me an inquiry for customized high-precision hydraulic cartridge flow control valve. The surface roughness of the inner hole is Ra0.2, and the cylindricity is Φ 0.003mm. Compared with the conventional hydraulic cartridge flow control valve, the precision is improved by nearly 10%. The cylindricity and the surface roughness of the inner hole are the core of the valve hole precision. There are no more than 5 hydraulic cartridge valve manufacturers in Ningbo that can successfully sample at one time. Seven days later, Brand told AAK that the price was 20% higher than that of the other hydraulic valve manufacturers. With such a large difference, I knew that there was no comparability. The price and hydraulic cartridge flow control valve were visible, but the manufacturing quality was invisible. 40 days later, Brand asked by email how long it would take to sample the hydraulic cartridge flow control valve quoted last time. I was a little surprised. After communication, we learned that the he chose the manufacturer who has cooperated with them for 3 years to make samples for this high precision hydraulic cartridge flow control valve, but proofing failed for 3 times. There was still a 5% discrepancy on the surface roughness and cylindricity of the inner hole of the hydraulic cartridge flow control valve, which could not be achieved all the time. Their engineer blamed brand for poor procurement, and the boss was also unhappy with him. I told him that an American customer of AAK encountered similar problem a month ago, AAK solved it for him. When Brand learned of our successful case, he saw hope and was relieved. After 20 days, the samples of hydraulic cartridge flow control valve were sent successfully 2 weeks later, Brand informed that the surface roughness and cylindricity of the inner hole of the AAK hydraulic cartridge flow control valve and the accuracy parameters not only met the standard, but also improved by more than 10% compared with their original requirements. What's more surprising is that the overall operating efficiency of the system was also improved from 5% to 10% when the AAK hydraulic cartridge flow control valve was installed, which surprised their engineers. We were also complained about the surface roughness and cylindricity of the inner hole 5 years ago. Now AAK uses rolling technology to replace the traditional cutting method, uses rollers to roll the metal surface, flatten the convex part of the surface, and make the concave part bulge, and then process it into a smooth surface like mirror. The details of rolling technology need skills. The surface roughness of the valve hole processed by an old experienced craftsman will be nearly 1% higher than that of grinding, which is why we can reach Ra 0.15, and the cylindricity error is controlled within 0.003. After the working face is hardened, the wear resistance and fatigue strength are increased, which is also the advantage and feature of this process, but it requires experience to master it skillfully. AAK hydraulic cartridge flow control valve, high precision, high efficiency, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-flow-control- valves-aak3 , 62

What is the analogy for the relationship between the sales personnel of hydraulic manifold manufacturers and the buyers of importers? The teacher- student relationship may be the most appropriate. A few days ago, my leader complained about the teacher of his son. He asked the teacher twice, 'How has my son been doing at school lately?’ but did not get reply. I was stunned for a moment and suddenly remembered, a few years ago, I also asked customer Lina such a silly question, ‘How did Heidi, a sales representative of hydraulic manifold manufacturer AAK, communicate with you?’ Chinese elementary school teachers need to manage a class of 40 or 50 students, and they can only remember a few children who are particularly obedient or mischievous. For those they are not paying attention to, how can the teachers answer you? Besides, what about your child? Don't you have any idea? There are also questions like this that require the teacher to report to you, which can easily cause the teacher's aversion. Just like I asked Lina, ‘how did Heidi from hydraulic manifold manufacturer AAK communicate with you?’ This kind of question is impolite, and the customer basically responds perfunctorily. The correct way to open it is: Lina, Heidi from hydraulic manifold manufacturer AAK, thinks too much. Every time I communicate with her, I feel too tired. She has been bothering you lately, thank you.’ The very interesting aspect of human nature is revealed at this moment, and Lina is likely to deny or comfort me, saying, 'It's not as exaggerated as you said, but it's actually okay.'. The teacher-student relationship in school is the same. For parents of mischievous children, the correct communication posture with the teacher is not to praise their children, but to belittle them, so that the teacher understands that you know how troublesome your children are, and the teacher has to work harder for your children than other children. Implying a kind of understanding towards the teacher, it is naturally welcomed by the teacher. In business, when it comes to bringing people closer, sometimes a few thoughtful words may make them realize your uniqueness. Of course, to be a blacksmith, you need to be tough yourself. If the manufacturing quality of hydraulic manifold manufacturers is unstable, no matter how good customer relationships are, they cannot withstand the test of time. Managing the relationship with the teacher well can definitely add points to the child's future. Similarly, if hydraulic manifold manufacturers handle customer relationships well and reach a consensus on trust, placing orders becomes easier. Hydraulic manifold manufacturer AAK, focuses on manufacturing quality and also has the correct communication posture.

Peder is from a hydraulic equipment company in Peru. They mainly focus on logistics transmission hydraulic equipment. At the beginning of this year, customers complained about the unstable control and inaccurate positioning of the lifting hydraulic power unit they sold. The after-sales server judged on site that the problem was caused by the hydraulic cartridge needle valve in the system, but after the manufacturer's inspection, the parameters of the hydraulic cartridge needle valve met the requirements. The engineer asked the original manufacturer to optimize the hydraulic cartridge needle valve, but the manufacturer was unable to do it and gave up. Peder contacted more than 10 hydraulic cartridge valve manufacturers, but none of them had solution, Peder was very anxious. Peder found AAK website when searching in Google, and the background showed that he stayed for 9 minutes. He sent an email to ask if AAK has any optimization plan for the unstable control and inaccurate positioning of the equipment during operation caused by the abnormal hydraulic cartridge needle valves? According to the schematic diagram of hydraulic system and production drawings of hydraulic cartridge needle valve provided by Peder, after analysis, AAK engineers found that the original hydraulic cartridge needle valve design had shortcomings, and suggested a solution. Peder saw the hope and asked AAK to optimize the original design and make samples. After 45 days, AAK sent 40 hydraulic cartridge needle valves. Yesterday, Peder sent an email to inform that after using AAK hydraulic cartridge needle valves, the equipment has been running for more than 6 months. The customer has no complaints about unstable control and inaccurate positioning. AAK engineers only used a 6mm chamfer to remove the hidden danger of the original hydraulic cartridge needle valve. The overall flow coefficient of the hydraulic cartridge needle valve is required to increase with the increase of the opening. The inclination of the flow passage will have an impact on the pressure control of the throttle structure. The chamfering can reduce the generation of eddy currents, which guarantees the stability of the hydraulic cartridge needle valve from the source. AAK processed a 6mm chamfer at the chamfer position of the flow passage. This small trick reduced the average turbulent kinetic energy by 73%, reduced the pressure drop distributed at the outlet, and ensured the stability of the hydraulic cartridge needle valve. The flow can be adjusted steplessly to move or rise accurately and controllably under load, and the positioning is accurate. AAK hydraulic cartridge needle valve is stable in control and accurate in positioning. You can also have a small try! https://www.aakindustry.com/info-detai , l/needle-valves-aak434

Ewalz is from Turkey, and mainly purchases standard parts of hydraulic cartridge valves from Ningbo China. Recently, they developed a hydraulic manifold that requires the use of SUN proportional valves. He purchased it from a proportional valve manufacturer in Ningbo, and after 2 weeks of operation, the equipment experienced significant vibration. The on-site engineer found that the proportional valve was severely stuck. The original hydraulic valve manufacturer stated that this proportional valve is a replica of SUN, with fully calibrated parameters, but there are differences in performance. Ewalz was speechless and had to look for a new hydraulic valve manufacturer for this proportional valve. Ewalz browsed the AAK hydraulic valve website, stayed for nearly 15 minutes and left a message: 1.Does AAK have an existing program for benchmarking SUN proportional valves? 2.Can AAK completely solve the problem of valve spool jamming, vibration and noise? After communication, it was learned that the hydraulic manifold they developed was very tight on time, they had no time to customize it and could only choose the existing SUN proportional valve. The proportional valve produced by the original valve manufacturer has the same function as SUN, but has poor performance. This SUN proportional valve is widely used, and AAK have a record of 6 shipments last year. There has never been any jamming of the valve spool, and we have inventory, which fully meets his requirements. 2 weeks after AAK sent the SUN proportional valve samples, Ewalz informed us via email that the hydraulic manifold debugging was successful. 2 months later, Ewalz informed us that their engineers were satisfied with the AAK proportional valve. The root cause of unsatisfactory performance of the original valve manufacturer's SUN proportional valve lies in its accuracy. The vast majority of proportional valve manufacturers have a cylindricity machining accuracy greater than 5um, which is 70% lower than the SUN standard cylindricity. For the accuracy of proportional valves that is completely in line with the SUN standard parts, there are probably less than 3 hydraulic valve manufacturers in Ningbo China. AAK controls the accuracy of the proportional valve from 3 aspects: 1.AAK proportional valve spool control: The valve spool is produced using a German CNC lathe with one blade and then high-precision cylindrical grinding. The machining error is controlled within ± 1um, and the coaxiality and cylindricity are controlled within 3um. 2.AAK proportional valve hole control: Adopting Swiss honing processing, the accuracy can reach IT6-IT7 level, and the surface roughness can reach Ra0.2- 0.025um. 3.AAK proportional valve spool and hole fitting accuracy control: 30 years of experienced technician operation, fit tolerance zone hole H6, axis g5, fit clearance tolerance can reach 5-12um, valve spool without jamming. AAK proportional valve, no jamming, the manufacturing quality, function and performance, benchmarking SUN, you can give it a try.

Timothy from Italy has cooperated with AAK for 4 years. Our first cooperation started from hydraulic manifolds. In the first half of this year, their company planned to introduce a new, multi-functional hydraulic press at the exhibition. But the equipment debugging was not smooth, the operation efficiency was not high, and the energy consumption was also large. Their engineer thought that a certain hydraulic component on the hydraulic manifold was insensitive and caused the problem. But after independent test, the components were normal. After comparing with the original design drawing of the hydraulic manifold for several times, problem still was not found. The technology department and the purchasing department shirked each other, and the boss got angry. If they missed the promotion, the project team would be dismissed. Timothy contacted the original hydraulic manifold manufacturer, but the manufacturer had no idea. Timothy was worried. Timothy emailed me about the solution for this hydraulic manifold. I jokingly said that it seems that no inquiry was sent to me for this hydraulic manifold before. Timothy thought I didn't want to participate because it was not produced by AAK. He explained that this is the hydraulic manifold manufacturer designated by his supervisor. According to the hydraulic schematic diagram and hydraulic manifold drawing provided by Timothy, AAK technical team found the cause 3 days later. I told him that AAK was 90% sure of its success in redesigning and testing the hydraulic manifold. Timothy learned that there would be a 6,000 US dollars development cost for the hydraulic manifold. He hesitated and asked me to wait for the news. I was a little surprised. The time was burning fast, why still wait. I didn't ask. 1 week later, Timothy sent me the bank slip for the development cost and reminded me that I must succeed, otherwise he would be in trouble. After 45 days, AAK sent 6 hydraulic manifolds. Two weeks later, Timothy told us that the equipment installed with AAK hydraulic manifolds had a smooth trial run and would not miss the exhibition period. Last week, Timothy said that the equipment promotion was smooth and the reservation exceeded expectations. The boss was very happy. He suggested that I hurry up to prepare materials. The first order of their hydraulic manifold could be issued to AAK next week. The hydraulic manifold newly designed by AAK has 3 key points. It is difficult to find a third hydraulic manifold manufacturer in Ningbo who can take these 3 points into account at the same time. 1. The overflow circuit in the original hydraulic manifold system is changed into an automatic unloading circuit, and then matched with the AAK logic cartridge valve. In this way, the heating of the system is reduced, the working performance of the system is improved, and the energy consumption is reduced by about 20% compared with the original design. 2. The differential circuit design simplifies the hydraulic manifold system, reduces the operation cycle of the hydraulic system from 30 seconds to 20 seconds, and greatly improves the production efficiency. 3. The three pump oil supply of the original hydraulic manifold system is changed to the two pump oil supply, and the return oil pressure is used to directly cool the return oil. In this way, the series link of the system is reduced, the system pipeline is simplified, the energy is saved, and it is helpful for energy consumption and efficiency. Timothy told me privately that without the support of his supervisor for the development fee of 6000 US dollars for the hydraulic manifold, he paid it by himself. The boss was surprised by his actions and appreciated him. He gradually replaced the original supervisor. AAK hydraulic manifold, energy saving, high efficiency, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-manifolds-aak361

If someone asks you to write down the operation steps of "pouring the drink from the plastic bottle into the cup", 90% of people think it is simple, and 3 steps are completed: 1. Open the bottle cap. 2. Pour the drink into the cup. 3. Close the bottle cap. I read in a book by a Japanese writer that it is actually 15 steps, rather than the 3 steps that 90% of people think. Pour a drink, take 15 steps, maybe you will laugh in your heart. Look at the decomposition action of pouring drinks by the Japanese writer: 1) Pick up the plastic bottle with your left hand 2) Grasp the cap with your right hand 3) Rotate the bottle cap anticlockwise to unscrew it 4) Put the bottle cap on the table 5) Change your right hand to hold the plastic bottle 6) Take the plastic bottle over the cup 7) Tilt the plastic bottle downward 8) Pour it to an angle that can make the drink pour out little by little 9) Restore the plastic bottle to the vertical state after pouring the drink 10) Put the plastic bottle on the table 11) Pick up the bottle cap with your right hand 12) Pick up the plastic bottle with your left hand 13) Put the bottle cap on the plastic bottle mouth 14) Turn the bottle cap clockwise and tighten it 15) Put down the plastic bottle with screwed cap What did you think of and what should you do? Seeing this, I quickly put down my book and drank some water, it is exploration in my eyes, admiration in my heart, and details of actions. In the workshop of hydraulic valve production, if every operation procedure of our company is more than 15 steps of the Job Manual, and it is written in such a deep and detailed way, then there will be no deviation in the staff training. No matter which operator is changed to operate, everyone is unlikely to make mistakes. I asked the production manager, production engineer, workshop director, section chief and operator of AAK Hydraulic Valve to reformulate the Job Manual of AAK Hydraulic Valve according to the 15 step beverage pouring method. They are also surprised, but they are very motivated to do this deep decomposition. Not only in the workshop, but also in the marketing department of AAK Hydraulic Valve. In terms of marketing, promotion and sales, how to manage the behavior in a specific and detailed way, rather than some abstract and non specific instructions that cannot be executed. Those mega enterprises may say "correct nonsense", but if we imitate it, we can not even know how we “die”. The Chinese language is really broad and profound. I have seen similar workshop propaganda in other hydraulic valve manufacturers before, "strengthening communication between operators", "Learn from old technicians" and "tidy up the operation post". "Work harder on accuracy to improve customer satisfaction". At that time, I was curious about the enterprise culture of the manufacturer. Now think about it again, these can't be called "behaviors", just slogans. Slogans on the wall, is it useful? No amount of abstract words can become a workbook. Our own personal behavior is also a reference. In our manners, behavior and other minor aspects, make up a solid lesson. Finally, we will review why it is difficult to persist in marketing and promotion. If you have never been to the seabed, how do you know about the underwater world? There are only 2 reasons for "not doing well": ① not knowing the "method". ② Know the method, but do not know "how to persist". AAK Hydraulic Valve, not only know, but also insist. https://www.aakindustry.com/info-de , tail/hydraulic-valves-aak360

Rogelio is from Spain and we met 1 year ago. He sent inquiries about hydraulic cartridge valves to AAK for several times. Some time ago, he came to me and asked for help to make a batch of hydraulic cartridge needle valves. The hydraulic cartridge needle valve used on the hydraulic cold drawing machine they sold to Vietnam has expired the warranty period and needs to be replaced. This hydraulic cartridge needle valve is purchased from HydraForce, and it is not a standard part. HydraForce said that this valve was produced 2 years ago, it is out of stock now and will take 3-4 months to produce it. But the customer was not satisfied with this time frame and complained to his boss. In order to catch time, Rogelio contacted more than 10 Chinese manufacturers of hydraulic cartridge needle valves. They either could not benchmark with HydraForce, or they could not meet the time, so Rogelio was anxious. Rogelio remembered that AAK had supplied HydraForce for 9 consecutive years. He believed that I can help him. According to the hydraulic cartridge needle valve drawings provided by Rogelio, the production time is only 30 days. I told him that the lead time was only 30 days, and the manufacturing quality of hydraulic cartridge needle valve was up to the standard of HydraForce, few Chinese hydraulic valve manufacturers could meet these requirements. Rogelio thought that I was ready to give up, he was willing to give AAK 40 days and paid for 100 hydraulic cartridge needle valves the next day. 30 days later, AAK sent 100 hydraulic cartridge needle valves to their Vietnam factory. Rogelio informed by email last week that it was out of his expectation that AAK still completed the production in 30 days. Their customer was very satisfied with their replacement of the hydraulic cartridge needle valves. Rogelio also specifically mentioned that he had asked more than 10 hydraulic cartridge needle valve manufacturers, their lead time was at least 50 days and can not 100% guarantee to benchmark the manufacturing quality of HydraForce. AAK was the only one that could catch up with the delivery date and also benchmarked the manufacturing quality of HydraForce. For this non-standard hydraulic cartridge needle valve, AAK has 3 advantages, which are beyond the reach of most hydraulic cartridge valve manufacturers: 1.AAK adopts Japanese OKK ultra precision machine tool, and the machining accuracy of components can reach 0.01~0.3μm. The precision of shape and contour is 0.003 - 0.1μm. Its production efficiency is 30% higher, which is the cornerstone of AAK's ability to catch up the delivery. 2. AAK has been hydraulic cartridge valve ODM manufacturer of 3 world top 500 companies for 10 years. Its quality control process is more strict than the ISO certification system. We have been focusing on details and constantly optimizing technology. 3. From material selection, process configuration, technical processing, production line quality control, component testing, workpiece surface treatment, benchmarking HydraForce, some of them are even beyond it. AAK hydraulic cartridge needle valve, benchmarking HydraForce, welcome to make a small trial! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-needle-valves- aak359

Some people say that the conflict between Israel and Palestine will stimulate the foreign trade market. Some hydraulic manifold manufacturers in China say they need to stock some standard hydraulic manifold parts or hydraulic cartridge valves that can be used in the military industry. I'm a bit surprised. I've only seen hype about consumer goods and fast moving consumer goods. Have you ever seen anyone hype about hydraulic manifolds and hydraulic cartridge valves? The heart to make a fortune can exist, but it must be obtained in a proper way. For the conflict between Israel and Palestine, God's way is higher than man's. For hydraulic manifold manufacturer business dealings, honest is better than shrewdness. The shrewdness of hydraulic manifold manufacturers can only win for a while, and the honest of hydraulic manifold manufacturers can win for a lifetime. Whether it is an individual or a hydraulic manifold manufacturer, both the scheming and honest are seen by heaven. In this lifetime, no matter what age, one must be an honest person. Hydraulic manifold manufacturers operate their business, regardless of the country of origin of the order, and they must do a honest business. Hydraulic manifold manufacturer AAK, focusing on the stability of manufacturing quality and benchmarking against the international market, has been supplying 26 countries for 13 years. Hydraulic manifold manufacturer AAK relies on 3 strengths. 1) The hard strength of the manufacturing quality of the hydraulic manifolds 2) Adhere to the ingenious strength of hydraulic manifolds peripheral innovation 3) Focus on the soft power of online trust of hydraulic manifolds When hydraulic manifold manufacturers do overseas business, they aim to build their own trust on the internet. Without trust, it is difficult to make a deal. Whether it's the conflict between Israel and Palestine, or the business fluctuating of hydraulic manifold manufacturers, Emotions are like tides; pain is like waves, with ups and downs. By calmly witnessing our thoughts and emotions, we can learn to accept them as they are without making negative reactions. Hydraulic manifold manufacturer AAK, can rely on 3 strengths, but someone do not think so. I do not evaluate whether it is right or not. A pessimist is always right, but an optimist always makes money. Hydraulic manifold manufacturer AAK, has maintained 3 strengths and always remains optimistic.

Consuelo is from a hydraulic equipment manufacturing company in Spain, and has been engaged in procurement for less than 3 years. At the beginning of last year, their excavator was complained. After checking, it was judged that the hydraulic cartridge counterbalance valve was leaking, and the valve spool was worn. According to the feedback from the original hydraulic cartridge counterbalance valve manufacturer, the valve spool is made of 12L14 free- cutting steel, which is commonly used in the industry. The only solution is to replace the hydraulic cartridge counterbalance valve with new ones, which means that the valves will need to be replaced every 8 months. Consuelo knew that his boss and customer would not be satisfied. He tried to find a new manufacturer of hydraulic cartridge counterbalance valve, but failed. Consuelo found AAK on Google, and noticed that AAK had introduced some customer cases about the difficult and complicated problems of the hydraulic cartridge counterbalance valve, and sent an email asking: Can AAK hydraulic cartridge counterbalance valve achieve no internal leakage and be durable for more than 1 year? After communication, we learned that the hydraulic cartridge counterbalance valve produced by the original cartridge valve manufacturer had internal leakage after being used for about 8 months. According to the schematic diagram of the hydraulic system provided by Consuelo, combined with the working conditions of the excavator, AAK engineers found that it was not only the problem of changing the material of the valve spool, but also the problem of optimizing the structure of the original hydraulic cartridge counterbalance valve. After 40 days, AAK sent 6 samples of hydraulic cartridge counterbalance valve. Last week, Consuelo said that he would purchase 120 hydraulic cartridge counterbalance valves to replace the ones currently used on the excavators. The excavators installed with AAK hydraulic cartridge counterbalance valve have been used for 10 months, and there is no complaint of leakage. AAK improved the original hydraulic cartridge counterbalance valve from the 3 aspects: 1. Change in material selection. AAK hydraulic cartridge counterbalance valve spool is made of 20CrNi2MoV high carburized bearing steel, which is more suitable. We never consider the general standard of the industry, but what material is most suitable for the working condition. 2. The change of the seal, the inner cone of the check valve spool and the lower end face of the valve seat form a line seal, the outer cone of the control valve spool and the through hole on the valve seat form a line seal, and the lower through hole section of the relief valve spool and the valve seat form a line seal. Three lines are sealed to ensure no leakage. 3. With the change of valve operation, the overflow valve spool slides to control the on-off of the oil outlet and the oil return port, with the help of the coordination of the control valve spool and the valve seat. Whether the load rises or falls, the check valve spool is opened and closed from twice to once, and the valve spool life is doubled. AAK hydraulic cartridge counterbalance valve, has no internal leakage and is durable. You can also try it! https://www.aakindustry.com/info-detail , /cartridge-counterbalance-valves-aak505

4 hydraulic valve manufacturers, made samples for 5 samples, but none of them were able to produce the hydraulic cartridge check valve with a length diameter ratio of 25:1 successfully. AAK adopted a special slender shaft processing technology, and the sample passed the testing successfully at one time, the parameters of the hydraulic cartridge check valve were up to standard, and the surface roughness was improved by 0.3%, and the geometric accuracy was improved by 0.8%. German customer was satisfied. Cheney is a senior buyer of hydraulic cartridge valves in Germany. He is good at dealing with different abnormal conditions of hydraulic valves, such as stuck valves, leaks, cavitation etc. But this time, he was trapped by a hydraulic cartridge check valve with the ratio of shaft length to diameter greater than 25. Four hydraulic cartridge valve manufacturers, made samples for 5 times, spent 10 weeks, but without any results. Compared with conventional valves, this slender shaft hydraulic cartridge check valve has poor rigidity, easy deformation, large vibration, difficult cutting control, and strict requirements for processing technology. This is the root cause of the failure of most hydraulic cartridge check valve manufacturers. Cheney sourced for nearly 1 week, but still no hydraulic valve manufacturer is willing to take over. When he was browsing B2B, he saw AAK and noticed that AAK had an article about the hydraulic valve with long length diameter ratio, so he left us a message. After several rounds of email communication, Cheney seemed to see the hope and sent the drawing of the hydraulic cartridge check valve to us. 2 weeks later, AAK sent 8 samples of slender shaft hydraulic cartridge check valve. 7 days later, Cheney emailed that the parameters of AAK slender shaft hydraulic cartridge check valve were up to standard, its functions were normal, its surface roughness was improved by 0.3%, and its geometric accuracy was improved by 0.8%, which surprised their engineers. The reason why AAK succeeded in the first time is due to following 3 points: 1. Selection of drill bit and fixture: match the appropriate long drill bit from 3 aspects of hardness, heat resistance and impact toughness, and adopt the clamping method of one clamp and one top, at the same time use flexible movable center to compensate thermal deformation elongation, so that the slender shaft can stretch freely after being heated to avoid thermal deformation. 2. Control of cutting amount and cutting fluid: reasonably select the drilling amount according to the length diameter ratio. During cutting, the cutting fluid shall be fully poured to inhibit the rise of working temperature, thus inhibiting the thermal deformation. 3. Sharp tool control: the tool change frequency is increased by 3 times. Effectively reduce the friction and heat between the trolley knife and the workpiece, and control the thermal deformation from the source. In recent years, AAK has successively supplied a Spanish customer with hydraulic cartridge check valves with the same length diameter ratio, and it is repeatedly ordered 4 times a year. Although it is difficult to machine the hydraulic cartridge check valve with long length diameter ratio, AAK has unique skills. The slender shaft hydraulic cartridge check valve of AAK, is purchased by a Spanish customer 4 times a year. Welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-check-valves-aak358

A few days ago, I received samples of hydraulic directional control valves produced by other manufacturer from my old customer Ahmik. Ahmik is from Israel and started purchasing hydraulic directional control valves from AAK 2 years ago. In August of the previous year, they developed a high-pressure hydraulic manifold and needed to purchase a hydraulic directional control valve. Ahmik purchased the hydraulic directional control valve from a manufacturer that has been cooperating for 3 years. After 6 months, there was leakage in the valve, especially severe wear and tear. The original hydraulic valve manufacturer stated that the high-pressure hydraulic directional control valve can only hold a service life of 6 months at present. Ahmik didn't quite believe it, so he sent me a sample to see if it could achieve a service life of over 1 year. We disassembled the original manufacturer's hydraulic directional control valve sample and frankly, the manufacturing quality is not poor. Why not wear resistant? Based on the hydraulic schematic and operating instructions provided by Ahmik, we understand that the problem lies in the material selection of the valve body. The original manufacturer used 45 Cr material to produce valve bodies, which is not a big mistake, because this is a commonly used material for valve bodies. AAK never follows industry trend in material selection and strictly selects materials according to the working conditions. If the service life of this hydraulic directional control valve needs to be over 1 year without any damage, while ensuring machining accuracy, efforts need to be made on the material of the hydraulic directional control valve, especially the wear resistance of the valve body. I recommended Ahmik to use 3Cr3Mo3W2V hot working die steel to produce the valve body of this hydraulic directional control valve. If the original manufacturer was unwilling to use this material or if the processing is difficult, AAK can complete it. 3 days later, Ahmik asked me to copy the original hydraulic directional control valve sample, because the original hydraulic valve manufacturer is not confident in achieving a service life of more than 1 year. Indeed, the processing difficulty of 3Cr3Mo3W2V hot work mold steel is higher than that of 45 Cr, and the accuracy error is large. However, AAK has already had multiple factual cases of processing this material. The hardness and wear resistance of 3Cr3Mo3W2V hot working die steel are the preferred choice for producing high-pressure hydraulic valve bodies, but most hydraulic valve manufacturers in China choose 45 Cr. This material also has one characteristic, the entire cross-section and mechanical properties of the material are very consistent, ensuring that the valve body is more resistant to impact and corrosion during the system operation process, and is safe for 1 year. AAK hydraulic directional control valve, under high pressure, is still safe for 1 year, you can also give it a try!
