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.

Every October is the peak period for overseas customer visits. Hydraulic manifold manufacturer AAK has received 5 batches of customers and 2 new hydraulic manifold customers. Isaac, an old friend of hydraulic manifold manufacturer AAK, comes from Russia and his name is closely related to our name AAK. He has been busy in Ningbo for 2 days this time. After discussing several new hydraulic manifold developments in the AAK conference room, Isaac took out a business card and asked me if I know about this hydraulic manifold manufacturer in Ningbo. He would like to take me to visit this factory. Their company's other team purchased 10 sets of SUN standard hydraulic manifolds from this hydraulic manifold manufacturer, and there were no major issues, but there was leakage in the plug that was integrated into the manifold.  From the business card, I don't know this hydraulic manifold manufacturer. It's a bit awkward to go to a factory in the same industry. Isaac seems to feel my concern. The idea he gave me was that after arriving at this hydraulic manifold manufacturer, if we knew each other, I would wait in the car. If we don't know each other, then I'll follow him. Due to Isaac's persistence, I can only drive him along. Isaac contacted the other party and made an appointment to arrive at this hydraulic manifold manufacturer after 2 hours. Fortunately, we didn't know each other after meeting. I gave Isaac a reminder that we didn't know each other, and Isaac asked me to follow him in. After looking at the workshop first, the factory is not big. This hydraulic manifold manufacturer only produces manifold blocks and reassembles purchased hydraulic cartridge valves and other hydraulic components into hydraulic manifolds. This type of hydraulic manifold manufacturer does not require high technical content. Isaac started discussing the leakage of the plug in the hydraulic manifolds with them, and the boss seemed very angry about why such a low-level error occurred. He called in 3 people to communicate face-to-face. From the perspective of the scene, I felt it like a dead cycle, no one was wrong. Alas! It's not easy for the boss of a hydraulic manifold manufacturer to encounter a prickly management team.  I don't speak, I'm only responsible for recording. The boss of the hydraulic manifold manufacturer questioned A, who was in charge of quality. A stood up and said, "Quality is produced." This statement has a killing effect and pushes the blame. The boss immediately asked B, who was in charge of production, but B said, "The quality of production is guaranteed by technology, and production is just an executor. I feel that this B is more piercing than A. The boss turned to C, who was in charge of the technical department and next to him. C seemed angry and said, "I have adjusted the program and handed it over to the production department. Quality supervision should be carried out in the later stage. Throughout the production process, no one has reported any issues. Now that the customer complains, they come to me. I won't take responsibility for this issue”. Isaac asked me what they were discussing, and I can only say that they seem to be looking for a reason. The meeting has finally come to an end, and the problem seems to have been resolved, but it also doesn't seem to have been resolved. What I want to say is that in the quality management of hydraulic manifold manufacturers, there should be processes and systems, especially a comprehensive quality system. Inspection is only a small part of the functions of the quality department. If there are quality problems with hydraulic manifolds in the production workshop, they should follow the process to deduce. The first step is to identify the fault phenomenon and summarize the information. The second step is to identify the cause of the fault and determine the responsibility (design, drawing, production, component, assembly). The third step is to sort out the original production quality management process, identify and supplement deficiencies in the quality management system process, and solidify it. On the way back, Isaac asked me what is my impression of this hydraulic manifold manufacturer. I'm not sure how many hydraulic manifold manufacturers like this are in Ningbo, the hometown of hydraulic valves in China. Upgrading to a hydraulic manifold manufacturer is not difficult for manufacturers who can produce hydraulic cartridge valves themselves. But hydraulic manifold manufacturers may not be able to produce hydraulic cartridge valves well. For the problems encountered by hydraulic manifold manufacturers, no one may be able to solve them, so hire someone who can solve them. However, this person can be very challenging, expensive, and even more difficult to manage. If someone is hired to handle the process, the participants will be linked to each other and if encounter problems, continuously optimizing the process. Use processes to solve problems and review potential quality problems. Hydraulic manifold manufacturer AAK in Ningbo China, do not choose prick, but the process.

Fossette is from a navigation and aerospace equipment company in Canada, and has been purchasing for 4 years. At the beginning of the year, their customer wanted to customize a marine hydraulic power unit, which was very strict with the hydraulic cartridge directional control valve. He contacted HydraForce for customization. Because of small quantity and tight time, HydraForce could not meet the needs of Fossette. He selected hydraulic cartridge directional control valve manufacturer in Ningbo, who has cooperated for 2 years, to make samples. The manufacturer guaranteed that the geometric accuracy of the valve spool and valve cage is 0.8μm, but it was jammed during equipment commissioning. The hydraulic cartridge directional control valve of this manufacturer is inflexible, and the accuracy is 50% lower than the requirement. At this moment, the manufacturer said that 1.2μm of hydraulic cartridge directional control valve is the limit, and their engineers can't fulfill their promises. Fossette contacted more than 10 manufacturers of hydraulic cartridge directional control valves, but it was also fruitless. The time was wasted for 6 weeks, the customer was dissatisfied, and Fossette started to worry. Fossette saw on B2B that AAK has released a customer case about "0.8μm Accuracy of hydraulic directional control valve", he left a message on AAK Hydraulic Valve website, asking 3 questions consecutively: 1. Accuracy 0.8 μm Hydraulic cartridge directional control valve, are you SURE? 2. Customization time? 3. The quantity is small, are you interested? He specially emphasized “SURE” in capital letters. He may be feared of being disappointed again. I told him that the precision of 0.8μm Hydraulic cartridge directional control valve, is already an existing fact for AAK, it is not a matter of SURE or not. I need a complete drawing to evaluate the probability of customization success as a whole. 40 days later, AAK sent 10 customized hydraulic cartridge directional control valves. After that, there was no email from Fossette, and I did not follow it. Generally, the customer will give a feedback 2-4 weeks after receiving the samples. 4 months later, just last week, Fossette informed us that his customer was very satisfied with the marine hydraulic power unit they provided. He was preparing for the annual order and asked me to keep an eye on the production in the workshop to ensure the progress and manufacturing quality of large goods. The hydraulic cartridge directional control valve accuracy within 0.8μm, challenges the processing equipment, the technical team and the manufacturer's quality awareness. 1. In terms of finish machining, OKK ultra precision machine tool from Japan is used, and AAK self modified fixture is equipped, accuracy of 0.8μm is not our limit. 2. AAK engineer team, in terms of the selection of raw materials and spare parts, starts from the requirements of working conditions and is targeted, never following the trend. Especially in the customization of high-precision hydraulic valves, the processing of production drawings, the preparation of processing technology, the technical control, they have unique skills and successful cases. 3. In terms of inspection, dare not be careless. The German Mahr cylindricity meter is used, with the help of EasyForm software, and 100% full inspection is carried out. Only those qualified can go to the packaging workshop. AAK hydraulic cartridge directional control valve, used in navigation and aerospace, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-directional- control-valv , es-aak372

Today, AAK posted a Pilot-Operated, Pressure Reducing/Relieving Valve benchmarking SUN Hydraulics' PPFB series, and we have developed 3 sub categories: E-PPFB-LAN; E-PPFB-LDN; E-PPFB-LWN. The working characteristics of this pilot operated pressure reducing/relieving valve are: the pilot operated valves exhibit exceptionally flat pressure/flow characteristics are very stable and have low hysteresis. Pilot operated reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves. The function of this pilot operated pressure reducing/relieving valve is to reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). In the past 6 months, AAK have received 2 orders from a Brazil customer. The selling points of this pilot operated pressure reducing/relieving valve are: 1. Control Pilot flow: 10 - 15 in³/min, Benchmarking SUN 2. The service life is 2 times that of domestic peers in China Technical parameters of AAK E-PPFB Hydraulic Pilot-operated, pressure reducing/relieving valve: Max. Operating Pressure: 350 bar (5000 psi) Capacity: 20 gpm (80L/min) Control Pilot Flow: 10 - 15 in³/min.

Coleman is from a hydraulic equipment company in Ecuador. He has been engaged in procurement for 3 years and has been quite smooth. In the second half of this year, the hydraulic winches they have sold out for 8 months was complained by customer that they were slipping under load and were prone to shake. After checking, it was found that the hydraulic cartridge counterbalance valve in the system was abnormal. The original manufacturer of the hydraulic cartridge counterbalance valve said that under such working conditions, the hydraulic counterbalance valves would need to be replaced every 8 months. The boss was not satisfied with this short service life and asked Coleman to find a hydraulic counterbalance valve manufacturer who can guarantee a longer service life. Coleman was surprised that all other hydraulic counterbalance valve manufacturers he contacted said that the original manufacturer was correct. Coleman saw AAK on Google and sent an email for inquiry with the attitude of trying. After communication, we learned his purchasing status. According to his hydraulic schematic diagram, working condition requirements, and hydraulic counterbalance valve drawings, AAK engineers also agreed with the opinions of the original manufacturer, but AAK has an optimization plan, and can guaranteed a service life of at least 16 months. When Coleman learned that AAK wanted to optimize the structure of the original hydraulic counterbalance valve, he hesitated and worried that it would affect the function, and his engineers may not accept it, so there was no news from him for a week. 7 days later, Coleman told us that he had no choice but to pay for the development cost by himself to request AAK samples. After 45 days, AAK sent 12 hydraulic counterbalance valve samples. Last week, Coleman sent an email to us that the equipment installed with AAK hydraulic cartridge counterbalance valves ran stably without any functional impact. 8 months have passed and the customer has no complaints. I told him that even in another 8 months, the customer wouldn't complain. AAK optimized the hydraulic counterbalance valve with minor changes in 3 aspects, which is not only more stable and better, but also more durable. 1. In the inner chamber of the hydraulic counterbalance valve spool, the boss for axial limit is machined. The piston slides in the second chamber. The rear end of the piston is equipped with a one-way throttling device (the first damper and the second steel ball). 2. The main valve spring adopts multiple spring structures with different stiffness, and the chute on the cone side of the valve spool can control more accurately and sensitively to prevent the load from stalling. 3. The second steel ball is placed in the third chamber of the piston and matched with the valve port of the first damper. The rear end of the screw plug is provided with a damper, which has two damping links. The utility model reduces the system pressure, reduces vibration, is beneficial to stability, and is durable.

Leila is from Russia. It has been 2 years since she purchased cartridge valves from China. She has encountered difficulties in the accuracy and stability of hydraulic pressure control cartridge valves. In February of last year, their hydraulic pile driver was complained by customers about its inability after 6 months of use. After checking, it was found that the hydraulic pressure control cartridge valve had leakage. The original manufacturer of the hydraulic pressure control cartridge valve advised that that this valve spool accuracy requirement was high, some hole accuracy of the valve spool may be not up to standard and caused the leakage. It could only be re-produced, which took 60 days. The after-service sales had to deliver other pile drivers to the customer for use instead temporarily. The boss was not satisfied with the original hydraulic pressure control cartridge valve manufacturer, and required Leila to re-purchase the hydraulic pressure control cartridge valve, which must be completed within 40 days. Leila was under pressure. Leila left a message on AAK website: 1. For the hydraulic pressure control cartridge valve, with accuracy of each valve spool is below 0.8μm and consistent, is AAK able to customize it? 2. Can AAK finish 20 customized hydraulic pressure control cartridge valves within 40 days? 3. The service life of the customized hydraulic pressure control cartridge valve shall be 18 months. This is about the accuracy, production time and service life of the hydraulic pressure control cartridge valve. After communication, I learned that she had trouble with the stability of the accuracy of the valve spool, and saw the information of AAK hydraulic cartridge valve on B2B. I told her that AAK had encountered these 3 problems before, and there were also practical solutions for customers. Leila asked me to make samples according to her drawings. After 38 days, AAK sent 20 samples of the hydraulic pressure control cartridge valves. Yesterday, Leila emailed us that the pile driver equipped with AAK hydraulic pressure control cartridge valve has been running for almost 1 year without leakage or complaint. AAK hydraulic pressure control cartridge valve has been approved by her boss. They are counting how many hydraulic pressure control cartridge valves need to be purchased to replace those with hidden dangers. With the recognition of her boss again, Leila was relaxed and pressureless. AAK hydraulic pressure control cartridge valve has fulfilled 3 major requirements of Leila, by making efforts in material selection of valve spool, component processing, equipment selection and quality control. 1. The valve spool material 20CrNi2MoV, imported from Germany, is adopted by AAK, combined with AAK's personalized carburizing pretreatment process, through secondary quenching + cryogenic treatment + low-temperature tempering process, the microhardness of the valve spool is 237~247 HV, and the service life of the valve spool has been increased by at least 3 times. 2. The processing equipment adopts Japanese OKK ultra-precision machine tool, and the old technicians operate the tool to ensure the accuracy of valve spool can reach 0.3-0.5μm. And the production efficiency is more than 30% faster than other machine tools. 3. In terms of the testing instrument, the German Diatest micro-pore diameter measuring instrument is used, which can inspect each valve hole accurately. AAK hydraulic pressure control cartridge valve, has consistent accuracy and service life of more than 18 months.

Evelyn is from a hydraulic equipment company in Mexico. He has been engaged in the procurement of hydraulic valves for 5 years and has been very successful. However, the hydraulic cartridge directional control valves purchased in the early stage fell down. At the end of last year, their excavator was complained by the customer that the output power was unstable. The after-sales server believed that the leakage of the hydraulic cartridge directional control valve was probably the cause. After disassembly, it was true that there was a gap between the valve spool and the contact point of the valve hole. The original manufacturer of the hydraulic cartridge directional control valve reported that after more than 10 months of use, individual leaks were unavoidable, and the hydraulic cartridge directional control valve could only be replaced. However, 1 month later, more and more complaints were filed. Evelyn realized that the service life of the valve produced by this manufacturer is about 1 year, or 500,000 to 700,000 times of performance. Evelyn started to send inquiries for "2 drops/min hydraulic cartridge directional valve with a performance of more than 1.5 million times". After 1 week, there was no quotation from any hydraulic valve manufacturers. Evelyn had a big headache. Evelyn found AAK on Google and left a message: 2 drops/min hydraulic cartridge directional valve with a performance of more than 1.5 million times, can it be guaranteed? I told him that this hydraulic cartridge directional control valve with high requirements for both function and performance is actually a benchmark for the manufacturing quality of HydraForce. AAK has served HydraForce for 9 consecutive years. If this is a real order, try it directly. If you just ask about the price, don’t waste time on both sides. After 35 days, 20 hydraulic cartridge directional control valves were sent out. Evelyn informed by email last week that the excavator with AAK hydraulic cartridge directional control valve has been installed for 1 year, and no customer complained about abnormal output power. I told him that the performance of this model can reach 2 million times, which is 3 times of that of your original hydraulic valve manufacturer, as long as no one does anything wrong about it. Evelyn is relieved. AAK can achieve 2 drops/min of hydraulic cartridge directional valve with a performance of 2 million times, which is the result of adhering to the quality standard of HydraForce. AAK spends no less than 400,000 dollars on R&D and technology upgrading every year. 1. AAK has produced OEM hydraulic valves for 3 world top 500 companies for 10 years. The self executing quality control process is more strict than the ISO certification system. It is focused on manufacturing details, process innovation and technology research and development. HydraForce and SUN Hydraulics are also loyal customers of AAK, and have been cooperating continuously for 9 years. 2. The AAK engineer team, in terms of the selection of raw materials and spare parts, starts from the requirements of working conditions and is targeted, never following the trend. Especially in the customization of hydraulic cartridge directional control valve with high requirements, there are some tricks and cases. 3. AAK has a self-developed test bench, each valve is 100% fully inspected from function to performance, while most hydraulic valve manufacturers just conduct random inspection. AAK hydraulic cartridge directional control valve, 2 drops/min, with a performance of 2 million times, you can also have a small trial! https://www.aakindustry.com/info-det , ail/hydraulic-directional-control-valves- aak37 , 1

Reading and earning money are the best practices in life. The former is not confusing, while the latter gives people dignity. It is important for hydraulic manifold manufacturers to earn money by reading more books. Many times, most hydraulic manifold manufacturers are not doing themselves, but imitating others. They are not operating their own hydraulic manifold manufacturers, but envying other hydraulic manifold manufacturers. They are not pursuing the manufacturing quality of hydraulic manifolds, but copying others' pleasure. The root cause of a person's unhappiness lies in comparison, comparison, and the final result is frustration and self denial. In life, we often only see the scenery of others, but ignore their vicissitudes. The most precious thing at the moment is what you currently have. Hydraulic manifold manufacturer AAK receives inquiries from customers every day, which is our most precious. Only by comparing fewer and cherishing more, can hydraulic manifold manufacturers gain a sense of trust. When no one helps you, stand tall on your own. When no one helps you, work hard and believe in yourself. As long as you are brave enough, there are no difficulties you cannot overcome! The best state for a person is not to expect or envy anyone, not to underestimate anyone, not to ridicule anyone, not to rely on anyone, to clarify and transparent their inner selves, to have the courage to say yes, and the confidence to say no! Whether brave or confident, there is a beauty like jade in books. Without sufficient orders, hydraulic manifold manufacturers are unable to read. Even holding a book but thinking about the order, you can't even read it. With sufficient orders, hydraulic manifold manufacturers can read effectively. Hydraulic manifold manufacturer AAK is reading while comparing its own online dissemination of hydraulic manifolds, thinking where else needs improvement. How can a hydraulic manifold manufacturer be able to get into a book if they lack money? Lack of money is a vicious cycle that is difficult to change. In this state, most of the decisions made by hydraulic manifold manufacturers may be wrong and short-sighted, focusing only on the immediate situation. How can there be good results? The anxiety of lacking money is the biggest anxiety among all anxieties. Many people say they are lost, but in fact, they are anxious about lack of money. To change this fate, they need guidance from a noble person. Hydraulic manifold manufacturer AAK has today's insights, and can always focus on the stability of manufacturing quality without comparing with domestic hydraulic manifold manufacturers. It is thanks to the distinguished customer of hydraulic manifold manufacturer AAK (the guidance of Honeywell, a Fortune 500 enterprise). If a hydraulic manifold manufacturer does not have stable manufacturing quality, no matter how beautiful the words are, they are all floating clouds. Hydraulic manifold manufacturer AAK in Ningbo China, makes money while studying, always remembers the words of the distinguished person and follow it, are also brave and confident.

Why is there only price war when there is no intermediary in cross-border e- commerce? Is there no selling point and no reason to buy? Chinese hydraulic valve manufacturers can't play cross-border e-commerce without their soft power and hard work. I have a friend. His factory produces leisure chairs. Three years ago, he started a cross-border e-commerce business of leisure chairs in Amazon. After several months of accumulation, he told me that the business was stable. Full containers were shipped to overseas warehouses. The average monthly sales volume was 1,000 pcs, the overall profit was 30%, and the flow was stable. I curiously went to his online shop to see, "There is no middleman making the difference, only my leisure chair", occupying a prominent position. I told him at that time that this model could not last, and he thought I was jealous of him. Yesterday, he complained to me. On September 1, a home furnishing big seller started to sell the same leisure chair at a 35% price reduction. As a result, his sales volume was only 50 pcs, and his traffic declined seriously due to the price reduction of the big seller. He had no choice but to reduce the price by 35%. Sell one now and lose 5 yuan. He is hesitating whether to continue the price war? If you don't, the traffic will disappear. If you do, there will be no bottom. Why did I tell him that this model would not work. Because I was impressed that it was just a brick mover, without the selling point of leisure chairs and no reason to buy, burning advertising to drive traffic. Is this cross-border e- commerce? With few or no peers, you can make big money with your eyes closed. As long as there is a peer, we must fight for the price.If a bunch of peers are here, the money earned should be vomited back slowly. A few days ago, I read a report that a delivery clerk at Amazon who had worked hard for 4 years received a dismissal letter from AI on his way to delivery, because it took too long and exceeded the standard operation time. Note that it is not HR. For repetitive, fixed action work similar to brick moving, AI can issue dismissal notice without HR in future assessment. People still need to think. Especially their soft power and hard work. Chinese hydraulic valve manufacturers, as cross-border e-commerce companies, should be careful if without endorsement of manufacturing quality. From beginning to end, online trust is the first priority. The content of the detail page of the Chinese hydraulic valve manufacturer must be of quality, not the hydraulic valve manual. Even if you want to send a lot of B2B information, let's say that the customer must know: 1) Why am I trustworthy? Many times, people are more important than goods 2) Why is the AAK Hydraulic Valve also trustworthy? 3) Compared with peers, what are the technical parameters and quality indicators of AAK hydraulic valve that have been compared with the international first-line brands? 4) Which 3 global top 500 and international brands are loyal customers of AAK hydraulic valves? It has been used for several or more years 5) AAK Hydraulic Valve, how to solve the problems of the hydraulic valves purchased by customers? 6) If you want cheap or low-quality hydraulic valves, you should not contact AAK to waste each other's time. Chinese hydraulic valve manufacturers must have quality in their work, which is not correct nonsense. The content is related to the customer and benefits the customer. This is the king of content. Chinese hydraulic valve manufacturers do not need to increase much flow. One inquiry of hydraulic valves from one target customer per day is OK, that’s 365 customers a year. If business is done with 10% of them, which are 36 customers. The small day of Chinese hydraulic valve manufacturers is OK. In fact, the same goes for salespeople. Isn't the salesman your own boss? The salesman who works to achieve the work goal is a fake salesman. AAK hydraulic valves, benchmarking the international first-line hydraulic valve brands, such as HydraForce, serving 3 global top 500 companies. https://www.aakindustry.com/info , -detail/chinese-hydraulic-valve-manufacturers- , aak370

1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way. Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time. I knew that AAK had passed the investigation period of German customers. After communication, I learned that the hydraulic cartridge check valves that he purchased in Ningbo 2 years ago, were tested with 6 hydraulic valve manufacturers before and after. Either the first sample was OK, but the second one was not up to standard; Either the existing valve was tested OK, but the customized valve was abnormal. Time was wasted and delayed their equipment development. It turns out that Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent to select new hydraulic valve manufacturers. This time, they will develop a hydraulic boarding bridge, which requires non- standard hydraulic cartridge check valves. From trial order to large order, AAK has been investigated for more than 1 year. Ferdinand said that the manufacturing quality of AAK hydraulic valves, whether the ones benchmarking international brands or non-standard customized ones, had been recognized by their engineers for their functions and performance, so they decided to place large quantity order of hydraulic cartridge check valves. The reason why AAK hydraulic cartridge check valve is different from other hydraulic valve manufacturers in Ningbo is that we insist on the quality of manufacturing. 1. Not make do with the equipment. No matter CNC machining center or machine tool, only high-precision ones are selected. At the same time, the fixture is upgraded and modified by ourselves, eliminating human error. 2. Materials should be paid attention to. Different kinds of imported high carburized bearing steel should be combined with AAK's proprietary heat treatment process. The hardness of the material has gone up several steps, and its wear resistance has been improved by more than 3 times. The thermal stability and compressive strength of materials have been far ahead of other hydraulic valve manufacturers. 3. The inspection is vigorous. The high-precision test bench and durability test equipment independently developed by AAK are used to conduct 100% full inspection. The pressure, flow and fatigue resistance of the valve cannot escape Sun Wukong's eyes. AAK hydraulic cartridge check valve, insists on high quality. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-check-valves-aak369

Today is Sunday and I woke up earlier than usual. I woke up at 4:00 and was alone in my study imagining the future of China hydraulic solenoid valve manufacturers. However, it seems that I can't calm down. Alibaba's layoffs are still in my mind. Is Alibaba's layoffs related to China hydraulic solenoid valve manufacturer AAK? Alibaba's massive layoffs have caught the attention of many people these days. During 3 years of the pandemic, there have been no layoffs, they have resisted but are now starting to lay off employees. After rolling up sleeves and working for 6 months, they realized that the arms were really cold outside. It's cold even in summer, how cold it will be in winter. Alibaba's layoffs are a step towards reducing costs, and a further step towards entering the era of meager profits for the internet. The further step is to prepare for a lasting war. The first ones to be cut are all P7, P8, and P9, and the HR of the big company is skilled. Objectively and calmly, the halo of the internet's frequent annual salary of millions is built on the dividends of the times. China hydraulic solenoid valve manufacturer, AAK, although working hard, at least do not feel cold. I know that it is important to deeply cultivate an industry, especially in the industrial sector. For example, for China hydraulic solenoid valve manufacturers, the competition is the boss's understanding, workshop manufacturing quality, and your customer base, especially high-quality customers. For example, AAK has Honeywell, a Fortune 500 company, and the industry leading companies HydraForce, SUN Hydraulics. It is difficult for China hydraulic solenoid valve manufacturers to have such gains or recognition if without rooted in the industry for more than 10 years. The world's giants are changing, and the China hydraulic solenoid valve manufacturer AAK also needs to change. Personally, I need to have more changes. Change is an upward ladder. This is the important change we are facing in 2023. Opportunities are hidden in change. OpenAI, launched ChatGPT that everyone is discussing; Elon Musk plans to spend $10 trillion to transform the Earth's Master Plan; Humans may have controllable nuclear fusion of "star energy"...... User psychology of solenoid valves, product trend of solenoid valves, process of solenoid valves, technology of solenoid valves, Change, change, change. In today's information age, almost everyone has "seen" these changes at the same time. I am not earlier than you, nor are you later than me. However, can we "understand" and become the core competitiveness. It will also widen the gap between each other. There are 2 ways to understand change: 1. Read more books. Every book can open up blind spots. The more you see, the more you think and understand. Standing on the 1st, 10th, and 100th floors has a completely different view. Read at least 20 books per year. For those with strong abilities, consider at least 50 books. 2. See more people. People are even more living books. Everyone has their own way of looking at problems and a dimension to think about the world. Entering a high-energy and high-density circle and field allows for access to more information and insights. Other people's words may be my enlightenment. Prospective cognition is hidden in the best and brightest people, to understand the changing world through their eyes, to hear the sound of change through their ears, to judge the opportunities for change through their brains. Read more books and meet more people. I wrote these 6 words on the homepage of my notebook 3 times. As a China hydraulic solenoid valve manufacturer, to meet with more high-quality solenoid valve customers on the road to change, is the 2023 Key target of AAK.
