Lateef, from Sweden, has been engaged in the procurement of hydraulic valves for 3 years and has been quite successful. Last year, however, he stumbled due to a hydraulic pressure control valve used in a hydraulic climbing vehicle. At the beginning of last year, their hydraulic climbing car was complained by customers that it was unable to rise. During after sales service, it was judged that the hydraulic pressure control valve was abnormal, and must be replaced. The original manufacturer refused to be responsible, because it has passed the 1 year warranty period. Lateef was embarrassed after checking, because after the hydraulic pressure control valves were shipped from the original manufacturer to their warehouse, their hydraulic climbing cars were delivered to the customer 4 month later, so the equipment was still within warranty. The boss was unhappy, Lateef was helpless. He tried to raise the warranty period of the hydraulic pressure control valves to 24 months to source new hydraulic valve manufacturers, but no reply from more than 10 manufacturers that he contacted. Lateef went from helplessness to anxiety. Lateef found AAK on B2B and left a message on AAK website: How long is the warranty period of hydraulic pressure control valve? I needed him to provide us drawings for discussion. According to his hydraulic pressure control valve drawing and working condition requirements, it is actually the standard part of SUN hydraulics. AAK has this procedure. I asked why he requires a 24 months of service life for the hydraulic pressure control valve, instead of requiring the number of durability times. Then he told me the above purchasing experience and sent me several hydraulic pressure valves from the original manufacturer. Our engineer found during disassembly that some valve spool cylindrical surface and conical surface, as well as the valve cage inner hole and conical surface are not concentric, which is a problem in accuracy and affects the function. The cone surface of some valve spool is worn, which affects the sealing, and the performance is not up to standard. Lateef was surprised to hear this, because no manufacturer gave him such analysis. I told him that AAK has a similar hydraulic pressure control valve. You can install it on the equipment for testing. If you can install it, you should not worry about customer complaints. He was surprised and happy. More than 10 hydraulic valve manufacturers had no reply, but AAK could send samples directly. 2 weeks later, Lateef informed that the hydraulic climbing vehicle equipped with AAK hydraulic pressure control valve could work normally. He also asked about the warranty period of the hydraulic pressure control valve. I told him that AAK was benchmarking SUN, and its performance was 2 million times. As long as the equipment was used no more than 2500 times a day, there was no problem in 24 months. AAK hydraulic pressure control valve, benchmarking SUN, adhere to 3 aspects, Lateef is completely relieved. 1. The material is strictly selected. The valve spool is made of 20CrNi2MoV from Germany. The wear resistance of the valve spool is more than 3 times that of the material used by other hydraulic valve manufacturers. The other manufacturers may have the performance of 500,000 to 1 million times, while AAK has the performance of 2 million times. 2. The precision is strictly controlled. The valve hole of this model is finely processed by American precision honing machine, and the precision of valve hole of other hydraulic valve manufacturers is 0.8 μm - 1.0μm, while AAK can be 0.6μm - 0.8μm. The precision is increased by 25% - 30%. 3. Strict inspection, equipped with a German Test high-precision measuring instrument for small micropore diameter, fully inspect each valve hole, while most hydraulic valve manufacturers only conduct sampling inspection randomly. AAK hydraulic pressure control valve, not only strict, you can also try a small order! https://www.aakindustry.com/info , -detail/hydraulic-pressure-control-valves- aak3 , 50

Gonzalo comes from Spain and has been purchasing hydraulic valves from Chinese manufacturers for 3 years. At the beginning of last year, they developed hydraulic gantry shears and needed to purchase hydraulic cartridge relief valves. The engineer directly purchased German HAWE standard parts, and the prototype was commissioned and purchased. The boss asked to reduce the purchase cost to match the market price of similar equipment. After comparing prices, Gonzalo selected a hydraulic relief valve manufacturer in Ningbo. 6 months after the equipment was sold, the customer complained that the hydraulic gantry shear was weak. During after sales service, the valve spool of the hydraulic relief valve was found to be worn and could only be replaced. The original manufacturer fed back that the service life of the hydraulic relief valve under 450bar high-pressure working condition was normal for 6 months. The boss was not happy. Gonzalo was under pressure. His engineer said that the service life of the HAWE hydraulic relief valve was no less than 1 year. Gonzalo contacted more than 10 hydraulic relief valve manufacturers, they could not bear high pressure or can not guarantee a service life of more than 1 year. Gonzalo found AAK in Google's China hydraulic valve manufacturers list. When he learned that AAK had engineer from HAWE, he saw hope. According to his hydraulic relief valve drawing, it is not too difficult, just needs to be high pressure resistance and performance. Because we have no program for this HAWE hydraulic relief valve, we need time to develop it. After 45 days, we delivered 80 samples of hydraulic relief valves, and told Gonzalo that if you replace those complained hydraulic relief valves with AAK's, you will have no pressure. A few days ago, Gonzalo sent an email. It has been proved that AAK's hydraulic relief valves can last for 1 year under high pressure of 450bar, more than twice as long as that of the original hydraulic valve manufacturer. In the subdivision field of high pressure resistance, AAK hydraulic valve manufacturing quality benchmark is HAWE, because HAWE is the No 1 of this field. We mainly focus on 3 points. It may be difficult to find the second one, from more than 200 hydraulic valve manufacturers in Ningbo. 1. Strict selection of materials: YG8 cemented carbide is selected for the valve spool of this hydraulic relief valve, and the content of tungsten carbide (WC) and binder cobalt (CO) is the best of the same kind of steel. The wear resistance and impact resistance have been improved by more than 2 times. Under the pressure of 450bar, there is no wear within 1 year. 2. The control equipment: the valve spool of this hydraulic relief valve is finely processed with a Swiss high-precision honing machine. The precision of the valve spool is fixed at 1-2μm, surface roughness Ra0.2-0.3, which is difficult for most manufacturers to achieve. 3. 100% testing: AAK independently developed durability testing equipment, implemented NFPA/T2.6.1 standard, and each hydraulic relief valve was inspected. Most manufacturers conduct selected checks and do not have good testing equipment. AAK hydraulic relief valve, resistant to 450bar high pressure, durable for more than 1 year, benchmarking HAWE, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak349

Peter is from Australia. One of his old customers wanted to purchase a special hydraulic flow control valve. Peter realized that the valve hole of this hydraulic flow control valve has high accuracy and is difficult to process. If the surface roughness and cylindricity error cannot be well controlled, it is easy to cause the valve spool to be stuck. As expected, he contacted more than 20 hydraulic flow control valve manufacturers in 3 days, but none of them was confident. The customer has urged the quotation twice, and now even the manufacturer can't be determined. Peter was very worried. Peter wanted to find more hydraulic flow control valve manufacturers in different countries online this time. He accidentally found AAK hydraulic valves and stayed on AAK website for about 20 minutes. With the attitude of trying, he sent me an email. After communication, we learned that his customer was pushing urgently and he needed AAK to quote asap. I didn't make an offer the next day. Maybe Peter thought AAK had surrendered. Later, I told him that most hydraulic valve manufacturers still use traditional processing methods to process the valve hole of this hydraulic flow control valve. According to the requirements of the drawing parameters, they also know that the surface roughness is a threshold. For example, the abrasive particles are easy to be embedded in the workpiece surface, and the cutting is not easy to be separated from the grinding oil, resulting in poor cleanliness of the grinding oil. All these affect the surface roughness. AAK realized this processing pain point as early as 4 years ago and adopted rolling technology to replace the traditional cutting method. I suggested that he communicate with the customer and let AAK directly test the sample. If the sample is successful, it will be quoted. If the sample fails, AAK will bear the development cost. On the 3rd day, Peter accepted my suggestion. After 35 days, 12 samples of hydraulic flow valves were sent out. About 2 weeks later, Peter said that his client confirmed AAK's hydraulic flow control valve. At this time, Peter realized the advantages of AAK and thanked me very much, which helped him face his old customer. Rolling technology and cutting processing are completely 2 different processing methods. AAK tried, solidified and mass produced it 4 years ago. Roll the metal surface with rollers, flatten the convex part of the surface, and bulge the concave part, and then process it into a smooth mirror like surface. The most important thing here is the rolling details. The surface roughness of the valve hole processed by the old experienced technicians will be increased to nearly 1% compared with the surface roughness after grinding, so that RA is 0.10 ~ 0.15, and the cylindricity error is controlled within 0.003. After work surface hardening, the wear resistance is improved, and the fatigue strength can be increased by 30%. There are many advantages, but there are not many manufacturers of hydraulic flow valves using this process, and even fewer can control the details. 3 days later, Peter sent the PO for the hydraulic flow control valve. He told me that the stone hanging in his heart finally fell, and the meal was more delicious. I told him that you only need time to receive the goods. Go to the bar when you need to, and leave the rest to AAK. AAK hydraulic flow control valve, has unique skills with special requirements. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak348

Quentin is from Italy. He is a new purchaser of a company which has cooperated with AAK for 4 years. He is very aggressive, but the first purchase of hydraulic relief valves overturned. At the beginning of this year, a batch of excavators of their company needed hydraulic relief valves, which were standard parts of HydraForce. Quentin asked more than 10 hydraulic cartridge valve manufacturers, and chose one manufacturer that is 60% cheaper than HydraForce to place an order. Six months later, trouble began. A customer complained that the oil pipe of the excavator burst. The engineer realized that it was not just the problem of replacing the oil pipe. It was found through inspection that the hydraulic relief valve was sluggish during operation, resulting in the instantaneous formation of peak pressure in the system, which caused the oil pipe to burst. The inner wall of the valve hole of these hydraulic relief valves was worn. However, the manufacturer of the original hydraulic relief valves said that it was caused by the unclean hydraulic oil, which had nothing to do with them. Quentin was afraid to take responsibility and dared not report to his boss. Quentin was very nervous. He contacted several manufacturers of hydraulic relief valves, but no gain. Carter, another old purchaser, saw that he was at a loss and suggested that he has a try with AAK hydraulic valves. Quentin emailed me and asked if the program of this HydraForce valve was available. Only then did I know that his first purchase of hydraulic relief valve was not smooth. I sent him the pictures and technical parameters of the hydraulic relief valve. The next day, he asked me to deliver 50 hydraulic relief valves first to solve customer complaints urgently. Two weeks later, Quentin informed that the replacement work was completed and the excavator could work. Quentin said that although the price of AAK is 30% higher than that of the original manufacturer with hidden quality problems, it is still 30% cheaper than that of HydraForce, and the surface treatment of AAK hydraulic relief valve is more textured than that of HydraForce. I told him that AAK hydraulic relief valve not only has the appearance value, but also has the performance of no less than 2 million times. The reason why AAK hydraulic relief valve can be compared with HydraForce is that AAK insists on selecting the most suitable steel, even if the processing cost is 2-3 times more expensive, it should also choose the best. AAK can't do anything that is not good enough, let alone give it to users. We always adhere to the following 3 points: 1. The material selection is "cleanliness". The A + material is used to replace the A material of the standard part. For example, 3Cr3Mo3W2V is used to produce the valve body of this hydraulic relief valve. Compared with similar steels, its hardness, strength, wear resistance and toughness have all improved to a new level. It ensures the impact resistance of the hydraulic relief valve during the working process of the system, and stands guard for the performance of 2 million times. 2. The selection of equipment is "guaranteed". The valve hole of the hydraulic relief valve is precision machined with Swiss high-precision honing machine, and the accuracy of the valve hole can reach 1.0μm, while most manufacturers of hydraulic relief valves are in the range of 2μm. 3. For surface treatment, AAK insists on using galvanized nickel alloy to replace the galvanized treatment of HydraForce. It is not only beautiful, but also textural. Quentin told me in private that in his conversation with me, he was more determined to do a good job in purchasing. This time, he solved the customer's complaints in time, and his boss was happy to see him. AAK hydraulic relief valve surpasses its domestic counterparts and benchmarkes with HydraForce. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak347

Many Chinese hydraulic manifold manufacturers are quite tired because they think too much and do too little. There are also Chinese hydraulic manifold manufacturers who cannot digest customer inquiries and still compete. A person's fatigue is also due to their desires and abilities, which cannot be directly proportional.   Little birds build nests in dense forests, all they need is a branch; The groundhog only needs to fill its stomach when it comes to the big river to drink water. The little dog is following you, what he needs is just a touch from you. Similarly, what people really need is actually very few, but people like to be greedy. So why live so tired? Because your desires are endless. The fatigue of Chinese hydraulic manifold manufacturers is also due to the desire for orders.   An inquiry is simple for Chinese hydraulic manifold manufacturers, but when the order arrives, can it be easily processed or digested? This is not only related to manufacturing quality, but also to daily production capacity and your goodwill.   Chinese hydraulic manifold manufacturer AAK focuses on manufacturing quality, including material selection, process settings, processing, equipment, and production line stability. Each process has standards and quality inspection. The manufacturing quality of AAK hydraulic manifolds lies in these 5 points. The manufacturing quality of hydraulic manifold is slower, more clumsy, and more solid than that of intelligent people. There is no shortcut on this road. There is no safe haven either. Without manufacturing quality as 1 takes the lead in the front, and any additional 0 added later will eventually return to zero. Just like in life, at the top of the waves, can you stand still? At the bottom of the waves, can you hold still?   A person's evil is usually obsessed with using bottomless methods to reach their goals. The evil of a Chinese hydraulic manifold manufacturer is also obsessed with taking orders without a bottom line. Whether it is a Chinese hydraulic manifold manufacturer or an individual, we must be kind. Good has no specific direction, whether for customers, suppliers, employees, or friends. Those who are capable rely on themselves for success, while those who are good rely on heaven for success. Heaven does not refer to God or immortals, but to the uncertainty of what one relies on.   Chinese hydraulic manifold manufacturer AAK has 1 inquiry every day, and 1-2 orders arrive every week, neither seeking nor greedy.   AAK HYDRAULIC VALVES (688) 2023-10-08 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak688

A China solenoid valve manufacturer needs to possess 3 elements, to gain customer trust: reliability, trustworthiness, and approachability.   Firstly, the sales representative (the person in contact with the customer) should be reliable. Reliable, one must be reliable, always have an explanation, everything has a place, and everything has an response. Only by meeting these 3 points, the sales representatives are reliable.    Secondly, trustworthiness. This is aimed at China solenoid valve manufacturers, with a focus on "credible". It does not come from the China solenoid valve manufacturers themselves, but from the social network in which they operate. For example, a young surgeon who claims to have worked at Mayo Clinic for 7 years has gained credibility in the medical industry solely based on this identity. For example, AAK hydraulic valve, AAK is the supplier of HydraForce for 9 consecutive years and Sun hydraulic for 5 consecutive years Good at various styles of Hydraulic Screw-in Cartridge Valves, Blocks, and Manifolds. My friend's company recruits drivers, but the first requirement is not the driver's skills, but these 3 points: first, the person has to get married; Secondly, he has to live with his family; Thirdly, he must have children, and the children must be at school. You see, these 3 conditions are all external social network conditions of a person. With these 3 conditions, he is likely to be a hardworking and caring person. So you see, the so-called ability growth is a part of one's own efforts, and the trust that can be gained in the appropriate social network is also a more important part. The same applies to enterprises, the manufacturing quality of Chinese solenoid valve manufacturers is a core part, but the trust that can be obtained in a suitable social network is also a more important part. Finally, approachability, this is a result. For example, the trust state defined by AAK and customers after several rounds of interaction. A person's abilities are reflected in 2 aspects: one is the reliability brought by improving their business abilities, and the other is the credibility determined by their position in the social network. The capabilities of a Chinese solenoid valve manufacturer are reflected in 2 aspects: one is to improve the reliability of the solenoid valve by improving its manufacturing quality, and the other is the credibility determined by its position in the social network, which is also the core of trust. AAK, a China solenoid valve manufacturer, uses its own reliability, credibility, and has gained the approachability to customers.

Elon Musk's acquisition of Twitter has already been implemented, which is also old news. Musk fired all employees of a total of 12 floors. Now Twitter has less than 50 core staff maintaining the operation of Twitter, which had 7,500 employees in 2021. Musk said that it is unnecessary to hire so many lazy people who do not work. Why does Musk do this? Maybe only he knows it best. The impact on me is that the values distinguish different people. AAK hydraulic manifold is to screen and eliminate people with efficiency.   Musk is a person who pursues the ultimate efficiency. The first thing to do in acquiring Twitter is to screen out the people who can work at the speed and efficiency he requires. A person who is highly demanding of his own efficiency can hardly bear the inefficiency of others. Frankly speaking, I also have this tendency. 996 is a holiday for me, 007 (from 0 to 0, 7 days a week without rest) is my normal state, especially in the early days of entrepreneurship, 612 mode every day (going out at 6 o'clock in the morning, going home at 12 o'clock at night). 365 days a year, 362 working days, only 3 day of holiday during the Spring Festival. For AAK hydraulic manifold, every internal meeting, I often say: I can accept that you are not so smart and have a low starting point, but I can hardly accept that you are not diligent enough, work inefficiently, meet problems mechanically, or avoid problems and choose to lie flat. When you meet problems, solve them, do not escape, do not throw away the pot, and constantly improve your knowledge system of hydraulic valves, as well as service awareness, you can make rapid progress.   If two people with different values work together, when the values of efficiency and comfort collide, there will be a great sense of tear, and both parties will suffer. Like fire, meeting ice. Only when "ice" evolves into "flammable ice", which looks like ice and burns when it meets fire, can the two sides merge, and then react, and the collision produces amazing energy. In AAK hydraulic manifold, in a word, whoever suffers will change.   In the 13 years of development, AAK hydraulic manifold has also taken a detour and paid a price, especially at the level of management efficiency. At the beginning of the establishment of AAK hydraulic manifolds, everyone started in one direction; Work hard. But then they began to expand themselves. Some managers showed that they were busy and important by increasing the number of their small teams and splitting the workload. They felt that AAK hydraulic manifold could not do without him, which dragged the development of AAK hydraulic manifolds.   From the perspective of humanity, I share the story of my high school classmate who worked in the middle level of SAP's Shanghai office in Germany. Some time ago, since the epidemic, SAP business has been cumbersome, and the number and difficulty of things to be handled have become increasingly large. He used to make few mistakes, but recently he has become more and more powerless. Being criticized by the boss and questioning how old employees can make such mistakes? Whenever he left his boss's office, he heard his boss's heavy sigh behind him. What will he do? His son's tuition in the United States is high, and Shanghai's housing loan is also heavy. He drove the car, feeling melancholy, and came to the garage. The lights in the garage were bright and dark; The smoke in his hand was extinguished and lit again, and it was quiet for a long time.   He knew that he had only 3 choices: 1. Resign and transfer the position to a better person. 2. Hire a better person to help yourself. 3. Appoint two people who are slightly lower than you as assistants to do a good job together. Most people will choose the third one. First, once you resign, you will fall into an economic crisis. Second, that person is likely to become a future opponent. Only the third is to find someone to share your work. Your son's tuition is available. Two mediocre subordinates are not threatening themselves. If there is too much of work to complete, they will find subordinates, and subordinates will find subordinates. The staff keeps expanding, everyone is busy, but the efficiency is extremely low.   AAK hydraulic manifolds, focus on efficiency, refuse to drag. The position of 1 person can give you 2 salaries, but you need to generate the efficiency of 3 people and the growth of 5 people. Yes, AAK hydraulic manifold is the one that requires, screens and eliminates people in the 1,2,3,5 mode. https://www.aakindustry.com/info-deta , il/hydraulic-manifold-aak430

These days, the 19th Asian Games have been going viral in Hangzhou. Due to the National Day holiday, all hydraulic manifold manufacturers in China are on vacation. I also visited the Asian Games in Hangzhou and visited a company started by a college classmate's child. My classmate also works for a hydraulic manifold manufacturer, but his son doesn't want to inherit his father's business to work at a hydraulic manifold manufacturer. Instead, he started an AI intelligent type company.   This young man has only graduated for 3 years, and the company's annual profit can exceed 12 million yuan, which can be considered a rapidly growing new company. It would be great if a new hydraulic manifold manufacturer in Ningbo can earn back their investment in 3 years. Even a hydraulic manifold manufacturer with a lifespan of 10 years can make an annual profit of over 12 million RMB, which cannot be found in Ningbo. I have summarized several key points for this young man's success:   1. To attend a good university, he graduated from Zhejiang University, similar to Stanford University in the United States, is quite outstanding in the field of computer science. 2. Choose a good major, he specializes in AI visualization. 3. There should be a good mentor, his entrepreneurship is facilitated by his mentor. 4. Have your own characteristics, be unique, and persist in being stubborn. 5. The clients are all among the top 50 in China and are all listed companies.   From this new type of AI startup, I thought of my hydraulic manifold manufacturer AAK. We may not have been successful yet, but along the way, we have also achieved several key points:   1. Hydraulic manifold manufacturers need to choose a good direction, most of which are concentrated in the domestic market, while AAK only focuses on overseas markets. 2. Hydraulic manifold manufacturers should have a correct concept, and AAK adheres to two major stability principles: quality stability and technical stability. 3. The hydraulic manifold manufacturer needs a customer who is similar to a VIP, and AAK is grateful for Honeywell's support. Their understanding and requirements have promoted AAK's growth. 4. Hydraulic manifold manufacturers should have their own characteristics, and AAK targets SUN's manufacturing quality, but the price is less than 70% of theirs. 5. Customers of hydraulic manifold manufacturers should be meticulous. If your customers only compare price, not quality, then your quality cannot be stable. AAK is fortunate to have Fortune 500 customers like Honeywell and industry- leading customer groups like SUN Hydraulics.   Hydraulic manifold manufacturer AAK, is slow hearted and diligent, implementing step by step, one key point, a good meal is never too late.   AAK HYDRAULIC VALVES (687) 2023-10-07 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak687

Colon comes from Turkey. They are distributors of HydraForce, Rexroth, Eaton, BUCHER, HAWE, and SUN hydraulics brands. They also often customize cartridge valves from overseas manufacturers. They have cooperated with AAK for 4 years. The AAK cartridge valve standard parts that benchmark SUN are loved by Colon. At the beginning of last year, Colon wanted to customize a hydraulic directional cartridge valve and expedite it.   After communication, it was learned that the hydraulic directional cartridge valve produced by the original manufacturer leaked due to the wear of the sealing ring after 6 months of use by the customer. The original manufacturer changed to use fluororubber sealing ring, but 6 months later, the old problem occurred again. The customer requested to use better sealing for the hydraulic directional cartridge valve. The original manufacturer prevaricated that the opening and closing work of the system is too frequent. No matter what material of sealing ring is used, the service life of the hydraulic direction cartridge valve can only be guaranteed for 6 months. The boss requested that the manufacturer of hydraulic directional cartridge valve be replaced, and the service life should not be less than 12 months, and the delivery time should be as fast as possible. Colon was in a hurry and came to me for help   According to his description, our engineer believed that the original manufacturer's judgment is correct. No matter what material seal ring is used, the hydraulic directional cartridge valve will have a service life no more than 6 months. Colon was a little confused: How can we explain this to the customer? 2 days later, I told Colon that replacing the sealing ring is not the only option to improve the sealing effect, but also to change the sealing method. Colon was very happy to know that AAK had an optimization plan. After 48 days, AAK sent 24 samples of hydraulic directional cartridge valves.   Yesterday, Colon emailed us and placed an order for 160 hydraulic directional cartridge valves. He told me that his boss and customer were very satisfied with AAK's customized hydraulic directional cartridge valve, which had no abnormality and leakage for 1 year. AAK hydraulic directional cartridge valve used a special PU polyurethane rubber sealing ring from Japan. At the same time, we made improvement on the structure of the sealing ring, to ensure 3 advantages: double sealing, zero leakage, and long service life. It replaced the valve produced by the original cartridge valve manufacturer, and also impressed the customer and boss.   1. The valve sleeve is connected with the valve body of the hydraulic directional cartridge valve by screwing. The first sealing device is set at the connection, equipped with L-shaped rubber gasket, and connected with the valve body by clamping. Most cartridge valve manufacturers dare not use these 2 connection methods.   2. The poppet spool of the hydraulic directional cartridge valve is inserted and connected with the valve sleeve by inlay. The right side of the poppet spool has a spring seat. The spring is connected with the poppet spool and the spring seat through penetration.   3. There is a second sealing device at the bottom of the thread at one end of the valve body of the hydraulic directional cartridge valve, which is connected with the valve body by clamping. There is a second sealing ring at the outside of the connecting clamp, and the other end of the valve body is also connected with the cover plate by screwing.   AAK hydraulic directional cartridge valve, double seal, zero leakage, long service life, no trouble in purchasing, you can also customize it! https://www.aakindustry.com/info-detail , /directional-cartridge-valves-aak502

Today, I want to make a plan, whether it is the marketing of hydraulic valves or the innovation of hydraulic valve production process. This is a definite action, but after the action is done, is it sure that it will pay off? This is a contradiction. More than 90% of people spend every day in this similar contradiction. More than 90% of people linger in contradictions. What to do on this day? Do certainty, uncertainty, or other things? But there is only one most important thing every day. For example, according to the short board theory of a wooden barrel, the height of water that a wooden barrel can hold depends on the shortest board. Should we make up for the short board immediately? Some people say that instead of making up for shortcomings, we should focus on the long board, do what we are best at, and do it easily. Who should we listen to? More than 90% of the people spend the day in contradiction, so do I. In fact, people are most vulnerable to the herd effect. Many of us deal with things every day in a perfunctory way when we go to work. At least 70% of us deal with it perfunctorily. This is because we are not active. In the hydraulic valve factory, for example, what steel has not yet arrived, what equipment is good, and what requirements are so high, his mind is always passive. Or, these passive ones occupy 70% of his time in a day. It's easy to be at a loss when you deal with the current things perfunctorily, it looks like that this is right and that is also right. You also want to do something actively, maybe you can start to do a little, but you can't persist, and then go back to the old situation. If people have knowledge but don't take action, then this knowledge is just bragging. Maybe it has flattered society, but people themselves have not improved. Then they feel good about themselves, which forms this strange circle. How can we break the circle? In AAK hydraulic valve, I cycle myself, practice and construct my hydraulic valve system again. One is practice and the other is hydraulic valve knowledge. Practice is hands-on, such as writing tweets and taking videos of hydraulic valves. From materials, equipment, process, technology, production line, quality inspection, pick it up again and go again. Although I am also in contradiction, I will rebuild the knowledge system of hydraulic valves in a cycle and go through another cycle. What are the advantages of this? Reconstruction and circulation, improve the brain. Practice should be consolidated, not to extend one's own knowledge, but to cycle knowledge and change the neural law of the brain. For example, in the practice of hydraulic valve system, write tweets, write every day, rebuild every cycle, and recycle every cycle. What is the essence of "Skill comes from practice"? Deliberate practice, repeated practice. People do things according to the rules of the brain. Do you think you can violate them? It's impossible. Since it's impossible, we should control our actions, thoughts, skills and knowledge according to the law of the brain. As a hydraulic valve manufacturer, your hydraulic valve innovation skills, technology upgrading skills, workshop management skills, continuous repetition and continuous circulation. Although we are in contradictions every day, we can still do something that can be determined. In a broad sense, it is something that returns. Some people say Kevin is very capable. In fact, whether you are competent or not is the difference in your behavior consciousness. If you have the idea of "having to do it" or "having to do it, then do it", you will be slow to move, with average results and worse personal growth. I insist on "I want to do, do it and doing it well". If you persist longer, the effect will be better. This is the essential difference between "want to" and "have to". I insist that in the hydraulic valve system, practice, repeat and recycle. In this way, my brain can push me forward with strength, and my brain will become more and more useful. I came from an engineering background. After I learned a skill, I practiced it repeatedly and deliberately in real combat until I became a skilled worker. Such a disadvantage is that my thinking is trapped at the bottom of the well and I become a frog at the bottom of the well. Fortunately, I woke up early and involved some books in the arts, such as economics, history, politics and philosophy. These gradually pulled me out of the well and made me more comfortable in how to "sit at the bottom of the well", and how to "climb out from the bottom of the well". ​​​ In daily work, we are almost always controlled by invariance. In fact, we are not intentionally unchanged, but controlled by the shortcut keys of the brain. This kind of reincarnation controlled by the brain's nerves has always made struggling people reincarnate in their minds, and salted fish can hardly turn over. At this moment, perhaps we all understand that there are only 2 reasons why things can not be done well: 1. Do not know the method. I know the method, but I don't know how to insist. AAK hydraulic valve adheres to the difficult road, adheres to the “stupid” Road, and is not afraid of going far. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak346

Milan from the Netherlands is an old customer of AAK. He purchased many non- standard customized hydraulic counterbalance valves from AAK. In March this year, Milan asked by email: can AAK design hydraulic counterbalance valves to reduce the energy consumption of equipment? It was learned that a hydraulic elevator developed by their company focused on the selling point of "low energy consumption and high efficiency", but after equipment commissioning, the energy consumption was not as good as expected and could not be promoted to the market. Their engineer knew that it was the problem of the hydraulic counterbalance valves, but there was no improvement after making efforts for several times. Milan contacted a number of hydraulic counterbalance valve manufacturers, but there was no gain. He was very anxious. According to Milan's hydraulic schematic diagram and the original design drawing of the hydraulic counterbalance valve, AAK engineers analyzed that the problem really lies in the control of the hydraulic counterbalance valves. AAK can redesign the hydraulic counterbalance valve with 90% confidence. Milan seems to have no better choice. He paid $2,000 development fee. After 50 days, AAK sent 20 samples of hydraulic counterbalance valves. Last week, Milan sent an order for 600 hydraulic counterbalance valves. At the same time, he informed that based on AAK newly designed variable pilot ratio hydraulic counterbalance valve, their engineer adjusted the working conditions of the equipment, improved the hydraulic principle, and saved more than 30% of the energy consumption of the hydraulic elevator. The promotion at the exhibition was also very smooth, the booking was hot, and their whole team was happy. But I'm a little unhappy. The price of Milan's regular order has dropped by 40% compared with the trial order. I told him that you can't let me "earn some money from selling cabbage with the heart of selling Heroin". Milan may also be amused, and directly revised it to the original price, only stressing the need to ship on time. How do AAK engineers design variable pilot ratio hydraulic counterbalance valves? In fact, it is simply based on Milan's energy consumption pain point, fight to the end. The variable pilot ratio hydraulic counterbalance valve is an innovation from the mechanical structure of the valve, which utilizes the characteristics of variable pilot ratio and pilot pressure. When stable, a low pilot ratio is used, and when unstable, a high pilot ratio is executed. Compared with the conventional standard hydraulic counterbalance valves, the pilot pressure required for full opening can be 30% lower under the same pressure and flow. At the same time, AAK's variable pilot ratio hydraulic counterbalance valve can keep the oil cylinder and motor moving more smoothly and quickly. Compared with the original hydraulic counterbalance valve, the energy consumption can be reduced by 30%. Milan privately told that as long as the purchase of the hydraulic counterbalance valve was successfully completed this time, he could be promoted. AAK variable pilot ratio hydraulic counterbalance valve, energy saving 30%, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valves-aak345

Cemeh comes from Russia, and has been purchasing hydraulic valves smoothly. At the beginning of this year, he was very passive when purchasing a hydraulic pressure control valve that can withstand high pressure of 450bar. Their hydraulic power unit used in the aviation industry requires the use of hydraulic pressure control valves with high precision requirements and high pressure resistance. Cemeh made samples from a hydraulic pressure control valve manufacturer who has been cooperating for 3 years. The equipment has been debugged twice, and when the pressure reaches 450bar, there is a leak in the hydraulic pressure control valve. The original hydraulic valve manufacturer stated that due to the need to withstand high pressure of 450bar, the valve cage material can only be selected from high carbon chromium bearing steel, which has high hardness and is prone to precision errors during processing. Therefore, the original manufacturer gave up. Cemeh contacted other hydraulic valve manufacturers in China but was unsuccessful. Cemeh browsed AAK website on B2B and then introduced himself by sending an email asking 3 questions: 1.Can the AAK hydraulic pressure control valve be leak free at a high pressure of 450bar? 2.Can the AAK hydraulic pressure control valve be durable for more than 1 year at a high pressure of 450bar? 3.Is AAK interested in developing their small qty of hydraulic pressure control valves? Based on his message, I judged that the hydraulic pressure control valve he purchased either cannot withstand high pressure of 450bar or has a service of only a few months. After communication, it was learned that the hydraulic pressure control valve from the original manufacturer leaked when pressurized. I provided a case of a Russian client for his reference. The AAK hydraulic valve was used on aircraft by a Russian client in 2019. And tell him that AAK's high-pressure hydraulic pressure control valve is based on HAWE's manufacturing quality, function, and performance. Without further questioning, Cemeh just asked: Can AAK make sample for hydraulic pressure control valves based on his drawings? After 35 days, AAK sent out 20 hydraulic pressure control valves. After receiving the samples, Cemeh informed us in the second week that the trial run was successful. 2 months later, Cemeh sent us an order for 420 pcs of hydraulic pressure control valves. Although the components of this hydraulic pressure control valve are difficult to process, AAK controls from 3 aspects: equipment, tools, detection. 1. The customized diamond reamer, has the smallest blunt radius of the cutting edge, which is not easy to break, and is also completely cut. Moreover, the coefficient of thermal expansion is small, and the thermal deformation is small. Even when machining high carbon chromium bearing steel, the machining accuracy of the valve hole is within 2μm. 2. In the precision machining stage, using honing machines imported from the United States not only further improves high-precision dimensional tolerances, but also optimizes surface roughness. 3. In the detection process, we use a Japanese imported coordinate measuring instrument to detect the dimensions, shapes, and positional tolerances of the components. Ensure accuracy without blind spots or dead corners. AAK hydraulic pressure control valve, with a pressure resistance of 450bar, is calibrated against the manufacturing quality, function, and performance of HAWE. You can also give it a try!

Bernardo comes from a hydraulic winch manufacturer in Brazil, and has cooperated with AAK several times on non-standard customized hydraulic cartridge valves. At the beginning of last year, Bernard company needed to purchase hydraulic flow control valves for a batch of hydraulic winches. Due to cost pressure, the boss asked Bernard to reduce the procurement cost of hydraulic flow control valves by 10%. This hydraulic flow control valve needs to be the same as HydraForce standard part. After a round of sourcing, Bernard determined the manufacturer of the hydraulic flow control valve. 7 months after the sale of the hydraulic winch, a customer complained that the sealing ring of the hydraulic flow control valve was broken, resulting in leakage, which caused the hydraulic winch to rise powerlessly. 6 months after the original manufacturer replaced the sealing ring with new one, the old problem happened again. The customer complained directly to the boss, who asked Bernard to replace all the hydraulic flow control valves within 1 month and asked the original manufacturer to bear the costs. However, the original manufacturer could not reach an agreement. Bernard was caught in the middle. He was embarrassed for 2 weeks and made no progress. The boss was very disappointed with him. Bernard sent me an email asking about the time and cost of re producing the hydraulic flow control valves. He wanted to pay for it himself. According to the hydraulic flow control valve drawings he sent, I realized that maybe only replacing with durable O-ring could solve his embarrassment. I sent him 10 O- rings for matching tests. A week later, Bernard told me that AAK O-rings could be matched with the original manufacturer's hydraulic flow control valves. He asked me to send 500 O-rings to Brazil as soon as possible, and he could finally have a good sleep. Last week, Bernard sent an e-mail to express his thanks. All these hydraulic flow control valves have been assembled with AAK O-rings. It has been more than a year, and there has been no complaint of leakage caused by the rupture of the sealing ring of the hydraulic flow control valves. The boss also praised him for solving big losses with small money. AAK's O-ring has 3 strengths: no sloughing, no extrusion and wear resistance. The material and structure of the seal ring directly affect the performance of the seal ring. The hardness, extrusion resistance, tensile strength and deformation of the material all determine the service life of the seal ring, and the structure of the seal ring also determines the sealing effect. AAK selects Japan's special PU polyurethane rubber sealing ring, and the lip compression of the sealing ring is strictly controlled between 15% ~ 20%. The wear resistance and high pressure resistance of this seal ring are more than 3 times that of other nitrile rubber seals. Most hydraulic flow control valve manufacturers choose nitrile rubber sealing ring, which is easy to be dislodged or extruded to cause wear. For high-frequency working conditions, the durability is 9 months at most. AAK hydraulic flow control valve, the O-ring used has 3 strengths and no leakage, you can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak344

Artem is from Belarus. A few days ago, he left a message on AAK hydraulic cartridge valve website: 1. Is AAK a manufacturer of hydraulic cartridge valves? 2. I need a hydraulic cartridge valve manufacturer with a dust-free assembly workshop. Can AAK meet this requirement? There are not many inquiries from customers who directly request that the hydraulic cartridge valve manufacturer be equipped with a dust-free assembly workshop. After communication, we learned that one of their high-end customers needs to purchase a hydraulic cartridge valve, and they are very particular about the residual dust of the valve. The source of goods must come from the dust-free assembly workshop of the hydraulic cartridge valve manufacturer. Artem checked with more than 10 hydraulic cartridge valve manufacturers in China, but none of them were equipped with a dust-free assembly workshop. I took a video of the dust-free assembly workshop that day and sent it to Artem. Then, Artem sent us his inquiry, very specific and high requirements, which is also my favorite inquiry. Hydraulic cartridge valve manufacturer AAK seems to rarely consider the dust-free assembly workshop as one of our selling points, as the vast majority of hydraulic cartridge valve manufacturers in China do not have this equipment. However, dust-free workshops still have hidden benefits, such as for the hydraulic cartridge valve customers who are very particular about dust, and more importantly, they can avoid artificial secondary pollution or residue mixing into the valve body, which may cause valve blocking. In the dust-free workshop of hydraulic cartridge valve manufacturer AAK, assembly workers pass through the dust removal room before entering the workshop and stay in the room for 5 minutes before the dust removal wall panel system starts working. Multiple dust removal jet equipment will automatically sense and start to remove residual dust from the workers. At the same time, the room floor is also covered with sticky paper carpet, which can remove dust and dirt from the soles of shoes. The assembly workshop of hydraulic cartridge valve manufacturer AAK is unique. Welcome to try it out!
