Recently, I wasn't sure if I was getting older or if I was under a lot of pressure from 3 clients who had ordered hydraulic manifolds at the same time. I had nightmares almost every day, and the sleep quality was always poor. Only taking sleeping pills could solve the problem, but long-term use of sleeping pills had side effects, so after taking them for a few weeks, I gave up. Engaging in hydraulic manifold design and production is indeed tiring. I tried to analyze the reasons why I had nightmares. Was it because of the pandemic last time that a large number of hydraulic manifolds were delayed, creating a psychological shadow? I have consulted a psychologist for psychological analysis and wanted to delve deeper into the meaning of dreams. I have contacted two psychologists, but they still haven't solved the problem and it has become even more serious. Afterwards, I reviewed my consulting ideas: the common sense among the public is that dreams come from contemplation, and endless analysis of the causes of dreams is like throwing oil to fight fires. Psychologists consult based on this common sense, so it's even more serious. My approach is to just solve problems, don't just think about getting things done in one step, take your time and improve step by step. If you can't sleep well every day for 7 days a week, then choose to take sleeping pills for 2 days first. This way, you can sleep well for 2 days. This not only avoids the side effects of taking medication every day, but also benefits from sleeping well for 2 days, which turns into 5 days a week without sleeping well. By changing the sleeping environment, such as the hardness of the bed, the height of the pillow, the orientation of the sleep, the indoor odor, the strength of the lights, soaking feet before bedtime, and massaging the entire body with a massage chair, it was found that soaking feet before bedtime improved sleep, resulting in only 4 days of poor sleep. Trying to exercise 2 hours before bedtime, such as running, shifting gears, basketball, and swimming, only to find that it's just physical fatigue that makes you tired. Doing tiring exercise twice a week can turn into only 2 days of sleep deprivation. From the situation of "not sleeping well every day" to the effect of "not sleeping well 1 or 2 days a week", the sleep problem has been solved for at least half of the time! This inspires me that when the problem arises, we should not daydream there. We must implement in action, and the concretization of the action is the right thing to do. The same applies to the innovation of AAK hydraulic manifolds. 1.AAK hydraulic manifold, do not invent, do not innovate comprehensively, only innovate locally in hydraulic manifolds. 2.The innovation of AAK hydraulic manifolds, focusing on functions, has one more function than peers, and can be promoted to the market. 3.The innovation of AAK hydraulic manifolds, focusing on performance, has a lifespan of over 20% longer than that of its peers, and can be promoted to the market. AAK hydraulic manifolds, slow heart, fast hands, 3 innovative principles, focusing on the manufacturing quality, function, and performance of hydraulic manifolds.

Last week, Beck from the United States sent an inquiry to hydraulic cartridge valve manufacturer AAK, with one only sentence: Please provide a quote for 1000 units based on attached drawings. Hydraulic cartridge valve manufacturer AAK did not provide a quote on the same day, but instead provided Beck with more information about hydraulic cartridge valve manufacturer AAK. Beck only replied with two words: Please quote. I feel like Beck is an engineer and a bit of cool. The day after we quoted the price, Beck directly sent the PO to the hydraulic cartridge valve manufacturer AAK. Such a fast ordering speed is rare, and I was worried about the price being quoted incorrectly. I double checked the quote immediately. AAK's price is correct, and I finally breathed a sigh of relief in my heart. I emailed Beck: you place an order in such a hurry, have you encountered any difficulties in purchasing from other hydraulic cartridge valve manufacturers? Beck's response is still simple: I have been following hydraulic cartridge valve manufacturer AAK for a long time, and I believe AAK is reliable. When the need from my client came out, I placed an order with AAK. A simple yet touching answer, reliable. I think the customer's evaluation of hydraulic cartridge valve manufacturers is reliable, and this is the highest evaluation. For example, hydraulic cartridge valve manufacturers always hope to find "reliable" talents to join the team. From selecting, educating, employing, and retaining people, I always consider "reliability" as the only criterion. Steve Jobs once said that an excellent employee can withstand 50 mediocre employees. Even more than that. And these excellent employees are usually 5% of the population. These 5% cannot be nurtured by "nurturing". We can only rely on "selection". Similarly, if customers want to find a reliable hydraulic cartridge valve manufacturer, they can only rely on selection. What is reliability? The hydraulic cartridge valve manufacturer AAK understands it as follows: reliable, with 4 levels of achievement: receiving and doing, speaking and doing, thinking and doing, knowing and doing. AAK has gone from selecting reliable people, enhancing team awareness, achieving customer requirements, to selecting high-quality customers, making AAK a truly reliable supplier. Hydraulic cartridge valve manufacturer AAK, with its reliable quadruple realm, aims to become a reliable person and do reliable things.

We have an old hydraulic valve customer in South America. He has only two hydraulic valve suppliers in Ningbo, one is AAK hydraulic valve and another one is some hydraulic valve manufacturer. According to his description, AAK accounts for 70% of his purchase of hydraulic valves in Ningbo. In fact, I am very satisfied with this share and will not strive for 80% or 100%. Let him always use AAK hydraulic valves to compare with other hydraulic valve manufacturers, and feel the advantages of AAK hydraulic valves at all times. Recently, He had a brainwave and wanted to purchase all hydraulic valves in one factory. In his email, he asked AAK to give some feedback on the quality positioning, industry reputation and price performance of another hydraulic valve manufacturer. To be honest, this request is very difficult for us, because as a mature hydraulic valve manufacturer, I am unwilling to answer such questions. Before answering this question, what is the sign of personal maturity? There is a good word called "suspended judgment". To put it bluntly, we are not in a hurry to stand in line. Let's see, hang up the judgment we should have first and don't let the boots fall to the ground. When a man is mature and faces any situation, he takes many factors into account. There is no simple right and wrong in his world. In today's digital age, we always try to turn people's vague attitude into a clear number. You have to give “likes” and “dislikes”, either fans or passers-by. In this context, most people's personality maturity slows down and is digitally trained to be eager to make a statement. Under the digitization, for those who are not easy to express their position, such people are out of the control of digitization. Such people are not only mature, but also have more advantages. AAK hydraulic valve only sticks to its own research and development, technical transformation, quality control and service, and never pays attention to the trend of local hydraulic valve peers. I don't know his quality, reputation and price. In fact, I don't want to know. Because I never pay attention to the hydraulic valve counterparts, and only focus on the international first-line hydraulic valve brands. AAK hydraulic valve, never commenting on its peers, only targets the international first-line hydraulic valve brands, and gradually surpasses those international brands. In particular, AAK quality is rooted in the top 1% of the subdivided field of hydraulic valves. AAK hydraulic valve, only go the right way, never afraid to go long way. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak235

Clinton, from Mexico, has purchased hydraulic valves from China for 6 years, and has cooperated with AAK in several non-standard hydraulic cartridge valves. Some time ago, some customers complained that their logistics transmission equipment was not easy to operate. After the after-sales inspection, it was found that the hydraulic cartridge relief valve on the rotary device failed to buffer and the pressure regulation was not smooth. The original manufacturer said that this hydraulic cartridge relief valve was benchmarked to the standard parts of HydraForce, and he was unable to optimize. Clinton contacted me and asked me how to make the hydraulic cartridge relief valve easy to adjust pressure and have buffering function. According to the hydraulic schematic diagram and the original hydraulic cartridge relief valve drawing provided, AAK engineer found that the requirements can be met as long as the original structure is improved. After 35 days, AAK sent 20 samples of hydraulic cartridge relief valves. Last week, Clinton sent a PO for 200 hydraulic cartridge relief valves. He said that when AAK hydraulic cartridge relief valve was installed, the customer no longer complained. It not only provided convenient pressure regulation and effective buffering, but also improved the stability of the equipment. They planned to replace the whole batch of equipment with AAK hydraulic cartridge relief valves. AAK hydraulic cartridge relief valve, the spool, buffer piston and pressure regulating valve housing cooperate to achieve buffer overflow effect, and the overall performance is reliable and stable, mainly from 3 unique structures: 1. The valve housing is provided with a first oil port, and the valve seat is provided with a second oil port. The valve spool can move axially, and the front end cooperates with the rear port of the valve seat to control the on-off between the second oil port and the first oil port. The channel port in the front end of the valve spool is provided with a plug, and the plug is axially provided with a damping hole. The front end face of the valve spool is equipped with a filter screen, and the front pressure surface of the valve spool is larger than the rear pressure surface. 2. The inner cavity of the front end of the pressure regulating screw nut has a buffer piston, and the rear end has a guide part. The radial bulge in the middle forms a convex ring part. The axial opening in the front end matches with the rear end of the valve spool. The oil supply in the middle of the convex ring part is with the connecting channel outside the rear end. 3. The pressure regulating screw is hollow at the rear end of the valve spool to form an inner cavity, which can move axially and change the axial force of the spring. The inner cavity wall of the front end of the pressure regulating screw is matched with the front end face of the convex ring to limit the buffer piston to move forward. For the optimized hydraulic cartridge relief valve, when the pressure at the second oil port rises instantaneously, the valve spool opens the overflow valve, so that the opening pressure of the valve is low, and the oil flows from the second oil port to the first oil port and fills the valve cavity. The oil in the inner chamber flows into the inner chamber of the buffer piston through the damping hole. If the pressure in the inner chamber of the buffer piston increases, the valve spool can be closed to generate secondary pressure, and the valve spool can be opened to overflow again to realize the buffer overflow function. AAK hydraulic cartridge relief valve, has buffer and is easy to operate. You can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak475

Dante is from a hydraulic manufacturing company in Greece. In the first half of last year, they wanted to upgrade the lifting stability of the company's original elevator. The function of the hydraulic cartridge counterbalance valve is the key. Dante made samples from a local hydraulic cartridge valve manufacturer that has been cooperating for 5 years. The stability has not reached the assumption of upgrading. After 2 times of improvements, the effect is still not obvious. Dante contacted more than 10 hydraulic cartridge valve manufacturers, but failed after a week. The boss urged the progress many times, and Dante was worried. Dante found AAK on Google, noticed that AAK had some customer cases about hydraulic cartridge counterbalance valves, and sent an email asking: Can AAK hydraulic cartridge counterbalance valve achieve fast start and stable positioning? After communication, we learned that they wanted to upgrade the equipment, and the key selling points of the equipment is to be started quickly and positioned steadily. According to the hydraulic system schematic diagram and the original hydraulic cartridge counterbalance valve drawing provided by Dante, after discussion, AAK engineers confirmed that the original hydraulic cartridge counterbalance valve can be optimized to achieve fast start and stable positioning. After 45 days, AAK sent 10 samples of hydraulic cartridge counterbalance valves.   2 months later, Dante sent an email saying that their engineers were satisfied with the function of AAK hydraulic cartridge counterbalance valve, which realized their lift selling points. Their sales team was confident to do a good job in market promotion and achieve the hot sale of equipment. AAK hydraulic cartridge counterbalance valve can solve the contradiction between response speed and stability, and has no back pressure effect. On the basis of the original, it has made 3 unique optimizations:   1. A fixed damping is installed between the inlet of the hydraulic cartridge counterbalance valve and the pilot oil port. The oil inlet of the valve body is 2 connecting ports of the oil circuit, and is equipped with a pressure gauge interface.   2. The valve spool of the hydraulic cartridge counterbalance valve slides in the upper and middle part of the valve body. The middle section of the valve spool has an inner concave ring, which is the inlet of the hydraulic cartridge counterbalance valve. The right end of the inner concave ring of the valve spool is processed into a conical surface. The conical surface is equipped with a two-stage stepped taper ring. The cumulative area of the conical surface is the same as the area of the cylinder end face at the right end of the valve spool. The stepped taper is adopted to realize the smooth flow change and smooth movement of the hydraulic cartridge counterbalance valve.   3. The cylindrical outer circle at the right end of the valve spool of the hydraulic cartridge counterbalance valve slides with the middle hole of the valve body. The adjusting screw is installed at the top pressure of the rear end of the balance adjusting spring. The adjusting screw is matched with the rear end of the valve body and controls the telescopic operation of the balance adjusting spring.   The optimized hydraulic cartridge counterbalance valve adopts the hydraulic control automatic closing valve to realize the unity of quickness and stability of the hydraulic cartridge counterbalance valve. At the same time, the pressure compensation is used to make the safety overflow function of the hydraulic cartridge counterbalance valve not affected by the back pressure. It can be applied to the hydraulic system with closed center and open center.   AAK hydraulic cartridge counterbalance valve, fast start, stable positioning, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-counterbalance-valves-aak474

A few days ago, I saw a video of Faye Wong's speech. She is a well-known singer in China. When she received an award, she spoke in this way, which roughly means: I know I sing very well myself, thank you for the recognition of my singing skills by the organizing committee, and I also acknowledge their appreciation level. Upon hearing this, I feel the same way. When hydraulic cartridge valve manufacturer AAK receives the first inquiry from a new customer, I always inform them that AAK has supplied 3 Fortune 500 companies. Thank you for your inquiry for hydraulic cartridge valve manufacturer AAK. I admire your vision in choosing AAK and believe that you are different from other customers, especially in terms of manufacturing quality. Why does Faye Wong sing well? Because she no longer needs to prove herself, let alone care about others will say good or bad about what she sings, and she only focuses on understanding the song and immersing herself in emotions. Singing is a pleasure for her. Such a confident person's voice is destined to be like a heavenly sound. If a person is not sure about her profession, I believe her profession must be flawed! If a manufacturer of hydraulic cartridge valves is unsure of his manufacturing quality, I believe that the manufacturing quality of the manufacturer is unstable. The charm of confidence is unstoppable. A confident hydraulic cartridge valve manufacturer brings customers a sense of security and trust. Perhaps there is someone else who dislikes Faye Wong's "unwavering" attitude and criticizes her, but never conceals the brilliance of such "superstars", making "white jade with slight flaws" more authentic. This world will instinctively accept the temper of the strong and call it personality. If there is no top-notch professional competence and confidence, it can only be criticized as arrogance. To put it plainly: Insolence requires capital! The insolence of a hydraulic cartridge valve manufacturer lies in its stable manufacturing quality; It's because other hydraulic cartridge valve manufacturers cannot do it, and he mass-produced it a few years ago; It's because other hydraulic cartridge valve manufacturers are competing for prices, while he is competing for technological upgrades. I really don't like people who like to label people. Just judging a person by their words is humble or insolent, and completely ignoring his strength. Note: Some people are humble because they have self-awareness. And some people are insolent; he's just telling the truth. Hydraulic cartridge valve manufacturer AAK in China is a bit insolent in terms of manufacturing quality, and maintains humility in dealing with people.

Someone asked me, you are not a mechanical professional. How can you guide AAK engineers to solve some difficult and complicated problems of hydraulic valves? Now the hydraulic valve industry has entered the stage of vertical specialization. Unprofessional may be a problem. Although specialization is the standard way to professional knowledge, it may not be a good thing from the perspective of creativity. Because sometimes professional knowledge is a double-edged sword. If you are too professional in hydraulic valves and have too much professional knowledge of hydraulic valves, you may not notice those distant associations. I have always insisted that the solution to the problem is to cast a big net first. Sitting next to the computer at 4:30 in the morning, I have 3 hours of association and quiet time. This is the darkness that does not belong to anyone. People usually wake up at 7:30, I have enough calm and patience to associate with the hydraulic valves and daydream at will. To do something creative, many people say that we should jump out of the box and think, but I think we should do the opposite and learn to think in the box. I often advise my engineers not to create the function of hydraulic valves by imagination, but to innovate on a certain basis of hydraulic valves. Ten years ago, we bought some representative hydraulic valve standard parts and some novel non-standard hydraulic valves from the top 10 hydraulic valve manufacturers in the world from the United States and Europe, comprehensively dissected these big brand hydraulic valves, refined the selling points of technical parameters, and then innovated on these basis. Only then did we have 3 domestic patents and processes and 4 proprietary technologies of AAK hydraulic valves, and AAK hydraulic valves were exported to more than 20 countries, 6 international first-line brand customers have placed orders for 5 consecutive years, and re-buy rate of AAK hydraulic valves from old customers is no less than 62% every year. What you think is right and what you can accept is basically wrong. What you think is wrong and what you can't accept are basically right. I read about 30 pages of books that are not related to the hydraulic valves every day. In the process of reading, I set aside a little time for daydreaming. For example, an idea in the book aroused my curiosity. I need to pause to connect my brain with this curiosity. Sometimes my brain will unconsciously link to the hydraulic valves. Every coin has two sides, depending on the angle we look at. For a half a glass of water, what some people see is: Alas, there's only half a glass of water left; What some people see is: Wow, still have half a glass of water. Pessimists are often right. I admire the pessimists' comments on the real world. Really, they are right, but most of them are losers. Simple minded optimists may not succeed, but they often live a good life. When I encountered the problem of hydraulic valves and couldn't find the answer after thinking hard, I found that sitting at my desk was almost a waste of time. Write out the hydraulic valve problem and knock it in the computer document, preferably on paper. Many people don't write it out, but trap the problem in their brain, which may not awaken their subconscious mind. Then, I will stay away from this hydraulic valve problem. Sometimes, when taking a bath or walking, the rudiment of the answer may come to mind. It's so wonderful. Turn off the music, stay away from the mobile phone, stay away from distractions, and let the brain unconsciously look for associations between different ideas. There may be surprises. Insist on getting up early, reading and exercising, because if you can't persevere, you won't get anything. Those who have not been engaged in the production of hydraulic valves for more than 10 years can hardly have a comprehensive understanding of hydraulic valves. Both enterprises and individuals should stick to their commitments to others, especially to themselves. I have no confidence in anything readily available, improvised and fast, but I believe in the power of stability, peace and long-term flow. Still water runs long. Any hydraulic valve manufacturer should be practical. I never believe that hydraulic valve manufacturers who lack self-discipline and self-growth will have a beautiful future. For example, in life, talented people are easy to bring traffic, but can't bring trust. The builder of self-discipline may not surprise people in a short time, but will gain long-term respect. This may be the cornerstone of trust. AAK hydraulic valves, no trickery, only daily self-discipline construction. https://www.aakindustry.com/i , nfo-detail/hydraulic-valves-aak234

After we posted the last article,“For hydraulic cartridge valves with high requirements, AAK produces them using 5-axis CNC machine tools, someone left a message: Can AAK use a 5-axis machining center to process hydraulic manifold blocks? From the IP, it should be a customer from Russia. Most hydraulic manifold manufacturers do not use this sophisticated equipment to produce hydraulic manifold blocks. How does hydraulic manifold manufacturer AAK use a 5-axis machining center to process hydraulic manifold blocks? Most hydraulic manifold manufacturers use domestically produced or Taiwanese machining centers for their hydraulic manifold blocks, because the accuracy requirements for most hydraulic manifold blocks are not high, and 5-axis machining centers are also expensive. Not every hydraulic manifold manufacturer can have a 5-axis machining center. Why this Russian customer requires a hydraulic manifold manufacturer to use a 5-axis machining center to process hydraulic manifolds blocks? He is likely to have encountered trouble with the valve hole accuracy of the hydraulic manifold blocks not meeting the standard. The higher accuracy the hydraulic manifold blocks require, the more they need to be machined on a 5-axis machining center. Today, the hydraulic manifold manufacturer AAK workshop was processing hydraulic manifold blocks on site, and I took a video for the processing. From the video, it can be seen that this is a horizontal 5-axis machining center from Japan. The advantage of this equipment is that the hydraulic manifold block can be processed with just one clamping of the blank parts. Most hydraulic manifold manufacturers process one surface before processing another, which not only has low efficiency but also poses risks of inaccurate positioning. AAK technicians first place the rough piece of the hydraulic manifold block on the fixture, position it while calibrating it with a balance ruler, then tighten the fixture and calibrate it again with a balance ruler until the positioning is correct, and then start the equipment. The dual box structure of this equipment ensures stable machining accuracy. Especially when the rectangular guide rail is combined with the movable mechanical structure of the column, the cutting becomes smoother and the accuracy of the valve hole is also stable. AAK hydraulic manifold blocks, processed with a 5-axis machining center, welcome to try it out!

An American IP left a message on our website: I saw your article "I regard quality as the highest principle of hydraulic valve manufacturing, why?". I want to know how AAK defines the quality of hydraulic valves. I specially checked the IP, which is an engineer from an engineering company listed in the United States. I thought for half an hour. To define a category, it must be comprehensive. What are the total quality of hydraulic valves? How much do we understand the quality of hydraulic valves? First, don't check the encyclopedia, Google, or hydraulic valve academic, but focus on hydraulic valve common sense. In common sense, how do you understand the quality of hydraulic valves, because our users also understand the quality with common sense. Friends who have read science and engineering know that there is a very famous management in Japan called total quality management. Of course, PDCA was invented by American Deming. What is carried forward is in Japan. The well- known Japanese enterprises implement total quality management. Almost all those engaged in manufacturing industry know total quality management, but few mention total quality. Some people say that total quality management has talked about total quality? Wrong, total quality management does not talk about total quality, only about management. For the total quality of AAK hydraulic valves, I have defined 4 kinds of quality. The 1st is the manufacturing quality of hydraulic valves, the 2nd is the service quality of AAK, the 3rd is the functional quality of hydraulic valves, and the 4th is the performance quality of hydraulic valves. The manufacturing quality of AAK hydraulic valves is now benchmarked with the international first-line brand, and the future is to surpass the international first-line brand. Especially in a subdivision field, such as high-pressure hydraulic valves, we should achieve top 1%. 1. AAK has been hydraulic valve ODM manufacturer for 3 of the world's top 500 for 10 years. The quality control process is strict and self-implementation is more strict than ISO certification system. 2. AAK has high-precision machine tools imported from Switzerland, Mikron GF high-precision CNC machining center and GILDEMEISTER turn milling compound machining center. 3. AAK has a full-time material engineer to check the selection of materials, which is responsible for screening, comparison, testing new materials connected with the Research Institute. AAK technical team has engineers from the world's top 500 hydraulic valve enterprises. They have their own experience in production drawing design, programming and production line quality control. Service quality of AAK: 1. AAK provides 24-hour responses, 48-hour solution plans and 72-hour problem solved before, during and after sales. Our peers dare to think but dare not to do it. 2. Six international first-line brand enterprises imported from AAK, because of feel at ease, all the hydraulic valves with low MOQ, high precision and urgent delivery, were purchased from AAK, due to AAK’s mindfulness. 3. 3-year warranty. Most of our peers dare not think about it, let alone do it. AAK hydraulic valve function quality and AAK hydraulic valve performance quality. First, let's find out what the function is and what the performance is? For example, 8 years ago, our mobile phones could not take pictures, but now smart phones can take pictures. Taking pictures on mobile phones is a function; The quality of pictures is a kind of performance. AAK hydraulic valve is differentiated and different by function and performance, especially in the field of high-pressure and high-precision subdivision, absolutely different. AAK hydraulic valve function quality: 1.The complete function of hydraulic valves is the least worth mentioning guarantee of AAK. 2.Each batch of materials shall be subject to heat treatment and never cut corners. Each hydraulic valve shall pass through the hydraulic table, with test reports and video records. Each hydraulic valve shall be tested 3 times and the test results shall be archived. 3.3 design patents, 4 proprietary production and processing technology, and the technicians in the core posts have been experienced for more than 8 years. Their proficiency is like a ruler. The old mechanic who has been in the factory for more than 10 years can sometimes judge the production status by just listening to the sound of the machine, and each production link of the hydraulic valves is engraved in his mind. Performance quality of AAK hydraulic valve: 1.The hydraulic valve with 3-year warranty has no vibration, no noise and high pressure resistance. 2.The machining surface accuracy of hydraulic valves is improved to within 0.3μm, the internal leakage can be less than 2drops / min. 3.Hydraulic valves with pressure resistance above 450bar and service life exceeding 2 million times, AAK hydraulic valve, Any valve, Any one, Any time, Any Where, just safety. Maybe I read too few books. I can tell you that almost no master, marketing master or management master has said the subject of total quality. At least, the concept of "total quality" has not been put forward in the hydraulic valve industry. I said a little more narrowly. For the definition of hydraulic valve quality, AAK is the first person to define the hydraulic valve quality with 4 aspects of total quality. AAK hydraulic valves, Any valve, Any One, Any time, Any Where, just Safety! https://www.aakindustry.com/info-de , tail/hydraulic-valves-aak233

Aether is a customer of AAK in Greece and has been purchasing hydraulic cartridge valves from AAK for 3 years. At the beginning of last year, he asked me about the sealing ring options available at AAK and I felt a bit strange. I didn't provide a direct answer and take an example, if I simply asked the doctor about the medication options, the doctor would definitely need to know the patient's symptoms or cause. After further communication, it was learned that they had encountered difficulties on a hydraulic directional control valve. Due to rapid wear of the sealing ring of the hydraulic directional control valve, there was leakage and the equipment was abnormal. The original manufacturer blamed the hydraulic directional control valve for being used too frequently, resulting in wear and tear on the sealing ring, which can only be replaced with new ones. Aether cannot accept replacing the sealing ring within only 3 months. Aether's demand is to address the issue of hydraulic directional control valve leakage without the need for frequent replacement of sealing rings. When I received the sample of the hydraulic directional control valve from the original manufacturer, I found that Aether had sent me an inquiry for this model before. I also understood why he only asked about the sealing ring at first. I told Aether that the original sealing method is a metal conical hard seal, which is difficult to ensure leakage if used frequently. Optimizing the original sealing structure can achieve no leakage for more than 1 year, but the production cost of hydraulic directional control valves would be increased. Aether was also candid and told me frankly that when inquiring, it was because AAK's price was more than 20% higher another hydraulic cartridge valve manufacturer that he chose. 60 days later, AAK sent out 50 samples of hydraulic directional control valves to address Aether's urgent needs first. Last week, Aether informed us that AAK hydraulic directional control valve has been installed on the equipment for almost a year and there are no leaks. Their customer is very satisfied, and his boss also suggested that he make AAK their preferred supplier of hydraulic directional control valves. The production cost of AAK hydraulic directional control valve is high, which is because these 3 aspects require more money than peers. AAK hydraulic directional control valve adopts a dovetail groove sealing ring through the valve spool pressure plate, which is pressed against the step hole of the valve body along with the valve spool, playing a sealing role. Oil cannot return from the inlet chamber to the return chamber, achieving zero leakage. 1. The hydraulic directional control valve body is connected to the spring seat, and the spring is fixed between the valve spool and the spring seat. There is a clearance fit between the valve spool and the valve body, as well as between the spring seat and the valve spool, to prevent the valve spool from moving inside the valve body. The guiding effect is formed between the spring seat and the valve spool, and the pre tightening force of the spring is changed by rotating the spring seat, thereby changing the opening pressure of the valve. 2. There are step holes on the valve body that guide the valve spool. There is a dovetail groove on the valve spool, which is equipped with a sealing ring to isolate the oil inlet and return chambers. Adopting a dovetail groove sealing structure and fixed by the valve spool pressure plate, it replaces the original metal conical hard seal. 3. The control rod is installed in the control chamber of the valve body, which has several oil passage grooves that return to the oil chamber and are fixed by elastic retaining rings. AAK hydraulic directional control valve, zero leakage, you can also give it a try!

Marten is an old customer from a Dutch hydraulic company. He is very cautious in the business of hydraulic valves and never changes hydraulic valve suppliers easily. AAK hydraulic valve reached the first cooperation of hydraulic relief valves under the introduction of his friend.  It has been 3 years, and he orders 2 types of hydraulic relief valves with AAK every year. We have a very good personal relationship, and often communicate about some hydraulic valve technology.   Last month, Marten had an order for a special hydraulic relief valve that requires a surface roughness Ra of 0.1~0.2μm, which is more than 4 times accurate than the normal standard.  All the hydraulic relief valves of this series are purchased from the hydraulic valve manufacturer that he has cooperated with for 5 years. This manufacturer has tried this hydraulic relief valve for 3 consecutive times, but the Ra value is still not up to standard.  Marten thinks of AAK hydraulic valve. In the email, he has been emphasized that the surface roughness Ra value of hydraulic relief valve must reach 0.1~0.2μm.  According to the hydraulic relief valve drawings sent by Marten, after discussion, AAK engineers expressed 90% certainty that the Ra value could reach 0.1~0.2μm.  Marten seems to see hope, but also fear.  He asked AAK TO try samples immediately. At the same time, the original hydraulic relief valve manufacturer was also requested to continue the sampling.   AAK arranged the most experienced technicians to operate the knife, first of all in the rough turning stage, cutting depth adjustment to 0.8~1.5mm, feed to 0.2~0.3mm/r, cutting speed to 30~50m/min and so on, after the rough turning Ra value is 12.5~6.3μm, while leaving 0.5~1mm as fine turning margin;  Secondly, in the finishing stage, the cutting depth is adjusted to 0.1-0.3mm and the small feed is 0.05-0.2mm /r. At the same time, the cutting speed is ensured to reach the moderate value and the roughness Ra value is ensured to reach 0.2-0.16μm.  AAK sent the hydraulic relief valve samples 10 days later.   On the 3rd day after receiving the samples of AAK hydraulic relief valve, Marten informed us by email that the Ra value of the surface roughness was up to standard. At the same time, he also informed that the original hydraulic relief valve manufacturer also continued the sampling, but failed in 5 samples for 5 times, while AAK succeeded in one time. He asked us to catch time to prepare material, he would discuss the PO of hydraulic relief valve with AAK after he confirmed the order quantity and the delivery date with his customer. For high precision hydraulic relief valve roughness Ra value, in addition to use high precision lathes, good technicians are the key, to be good at adjusting lathe parameters according to different processing, for this hydraulic relief valve, AAK technician advantages are reflected in:   1. High speed and small cutting depth and feed are selected to reduce the residual area and Ra value. When finishing, select high-speed and small cutting depth and feed rate to reduce the residual area and reduce the Ra value. 2. Grinding the front and rear tool surfaces of the turning tool with engine oil, can effectively reduce the Ra value of the workpiece surface. 3. The 32 year old mechanic operating the machine tool, who can know whether the Ra value of the hydraulic relief valve is normal or not by just listening to the processing sound. The Ra value of AAK hydraulic relief valve is 4 times that of the conventional standard and 2 times that of its peers. You can also have a small try. https://www.aakindustry.com/info-detail/hy , draulic-relief-valves-aak232

Mason is from a hydraulic equipment company in India. It has been 3 years since he purchased hydraulic cartridge valves from local hydraulic cartridge valve manufacturers in India. At the beginning of this year, their company developed a hydraulic crane and needed hydraulic cartridge counterbalance valves. They chose a local hydraulic counterbalance valve manufacturer who has cooperated for 5 years to make samples. During the equipment debugging, it was found that the crane vibrated during the descending process and the descending speed was abnormal. The after-sales servicer believed that the hydraulic cartridge counterbalance valve was abnormal. After the original manufacturer inspected the hydraulic counterbalance valves, all parameters were in accordance with the drawing parameter requirements. After internal discussion, it was concluded that the hydraulic counterbalance valve must be optimized, but the original manufacturer had no ability to do it. The boss asked Mason to look for overseas suppliers of hydraulic cartridge counterbalance valves. A week has passed, the manufacturer of the hydraulic counterbalance valve has not been determined yet. The boss was not satisfied. Mason began to worry. Mason found AAK on Google, stayed on AAK website for 23 minutes, and left a message: Can AAK design a hydraulic cartridge counterbalance valve to solve the instability and abnormal speed of the hydraulic crane during the descending process? For those who stay on AAK website for a long time, no matter which country they come from, as long as they are not hydraulic cartridge valve manufacturers, I will do my best to help. After communication, I learned that Mason was embarrassed to purchase hydraulic cartridge counterbalance valves. According to his system schematic diagram, hydraulic cartridge counterbalance valve drawing and crane working video, AAK engineer had a basic idea. 3 days later, AAK began to sample. After 40 days, AAK sent 6 hydraulic cartridge counterbalance valve samples. A month later, Mason emailed that after the new hydraulic cartridge counterbalance valve designed by AAK was used, the hydraulic crane did not shake during the load lowering process, and the speed was even. Their colleagues were very confident in the promotion of the cranes, and the boss was also happy. AAK does not use the traditional route to optimize the hydraulic cartridge counterbalance valve. According to the system diagram of the equipment and the abnormality of the crane, the hydraulic cartridge counterbalance valve is composed of valve body, valve seat, main valve spool, pilot valve spool and pilot mechanism. First, connect the valve seat with the valve body to establish a connected first channel. The extended end of the valve seat is connected with the pilot mechanism to establish a second channel. The main valve spool adopts sliding setting, and is equipped with throttling groove and orifice. Then the valve seat cavity is divided into 3 cavities, one end of the valve spool is in the inner cavity, and the other end is connected with the pilot mechanism. The valve spool is flexible, controllable and free from load interference. Last week, Mason told me privately that his boss decided to increase the purchase of hydraulic cartridge valves from China and give him more authority. He was more confident in his work AAK hydraulic cartridge counterbalance valve, is not only a surprise, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-counterbalance- valves-aa , k405

In the early stages of its entrepreneurship, AAK, like other hydraulic cartridge valve manufacturers in China, supplied to the domestic market. After a few years of turmoil, funds have become tight, and there are more and more customers on credit. The price competition has also become increasingly fierce. Most hydraulic cartridge valve manufacturers only focus on prices, do not make technological breakthroughs, and do not invest in innovation. I know that hydraulic cartridge valve manufacturer AAK must make changes and focus on the overseas market. My confidence stems from the stable manufacturing quality of AAK hydraulic cartridge valves, which are supplied to domestic listed companies, There is also the fact that it has never been returned. A few years ago, I didn't even know about 'brain science', I just knew I needed to write tweets, post B2B, shoot videos, and update on the website. Enquiries come one after another, including Fortune 500 companies, listed companies, and high-quality customers. Some hydraulic cartridge valve manufacturers also imitate AAK's approach by writing a few diaries, filming several videos, and doing several live broadcasts... but they can't bear it anymore, giving up is inevitable. Hydraulic cartridge valve manufacturer AAK has always insisted on writing, filming, and broadcasting. People may be curious in their hearts, where does that power come from? The answer lies entirely in brain science. In fact, many manufacturers who are persevering have not studied brain science, but their writing, filming, and broadcasting are in line with brain science, and those target customers are also people, and they must follow the principles and laws of brain science in cognition and thinking. In this way, those manufacturers who insist on writing, filming, and broadcasting will definitely have more inquiries and orders. Can we do business without understanding brain science? Of course we can. But when you understand brain science, your feelings, motivation, and mindset are completely different from before. This is how hydraulic cartridge valve manufacturer AAK gradually came to understand. The 4 books "The Consciousness Instinct", " Mind", " What Your Customer Wants and Can't Tell You", and " The Persuasion code" are all good for flipping through when you have nothing to do. If you have a lot of work to do every day, it's better to let it go for now. When you have free time, take it out and read it, perhaps it can help you understand many whys. Is the mind a product of the brain, or is it independent of the brain? Studying brain science, just like hydraulic cartridge valve manufacturers doing foreign trade, is difficult at the beginning. Just understanding a bunch of professional vocabulary first can make people retreat from difficulties. But when everyone has retreated, the hydraulic cartridge valve manufacturer AAK does not retreat. Keep going, haha, the taste is coming, and it's very good. These are new books from recent years, exploring the entry of brain science into the post brain science era, including the application of behavioral economics in marketing and sales. Just a reminder, reading these books makes it difficult for you to make money on a practical level, but I have gained a lot of inspiration from them. Hydraulic cartridge valve manufacturer AAK, has gained insights into brain science and has been involved in overseas trade.
