For a hydraulic cartridge pressure control valve with 3 high accuracy requirements, Jack spent 2 months on 3 cartridge valve manufacturers but the samples from all 3 factories failed. AAK completed the hydraulic cartridge pressure control valve with the main hole length diameter ratio of 10 in 25 days, and the main hole diameter tolerance is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra 0.2μm. Jack, from Melbourne, has been engaged in the procurement of hydraulic cartridge valves for nearly 3 years, with favorable wind and favorable water. Recently, he was trapped in troubles on the order of a hydraulic cartridge pressure control valve. His customer has strict requirements on the diameter tolerance, cylindricity and surface roughness of the main hole of the hydraulic cartridge pressure valve. He specially arranged 3 cartridge valve manufacturers to make samples at the same time. After 45 days, samples from only 1 of the 3 factories met the customer's requirements. However, in the first small batch order, the qualification rate of 120 hydraulic cartridge pressure valves was less than 60%. The customer requested to replenish the products, but the manufacturer had been prevaricating. Jack realized that he could only retain the customer by replacing the manufacturer of the hydraulic cartridge pressure valves. Jack browsed the website of AAK hydraulic valves through B2B and found that AAK had produced hydraulic cartridge valves with high precision in cylindricity, roughness and aspect ratio. He felt that perhaps only AAK can help him. He directly emailed us the complete drawings of hydraulic cartridge pressure valves. After several rounds of communication, I suggested Jack directly order 60 hydraulic cartridge pressure valves, which can be completed in 25 days. Maybe the trust level hasn't arrived yet, I did not hear from Jack for a week and did not push him. A week later, he suddenly sent the PO of 60 hydraulic cartridge pressure valves. Today, that is, 4 months after the 60 hydraulic cartridge pressure valves were shipped, Jack sent another PO for 300 hydraulic cartridge pressure valves of the same model. Jack's customers are very satisfied with AAK hydraulic cartridge pressure valves, and the 3 accuracies are all qualified. The diameter tolerance of the main hole of the hydraulic cartridge pressure valve is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra0.2μm. The customer should quickly replenish the inventory and designate AAK for production. AAK hydraulic cartridge pressure valve, meeting 3 precision standards, and is stable, because there are 3 guarantees in production: 1.Diamond reamers are used instead of conventional aluminum alloy reamers to avoid tool wear and effectively ensure the accuracy and quality of holes. 2.Set the best reamer parameters to ensure the form and position tolerance. The speed is 80-120 r/min, and the feed rate is 0.30 min/r. 3.90% of the medium oil is dissolved in 10% of the vulcanized chip liquid as the coolant to promote heat dissipation during processing, extend the service life of the tool, and protect the processing. AAK hydraulic cartridge pressure valve, is high-precision and stable. Welcome you to try an order! https://www.aakindustry.com/info-det , ail/cartridge-pressure-valves-aak421

James, a Brazilian customer, was in urgent need of purchasing 200 hydraulic relief valves within 30 days some time ago. The hydraulic valve manufacturer he chose to cooperate with got stuck in the hydraulic relief valve sample stage. The first time to send samples, the time was delayed by 10 days, and the hydraulic relief valve hole was also seriously deformed. The manufacturer said that the current processing of this valve hole was their limit, and asked James to contact other hydraulic cartridge valve manufacturers to take samples. James was speechless, and time was wasted. He consulted more than 10 hydraulic relief valve manufacturers and was advised that they were not able to meet the valve hole requirements, which made James a headache. James contacted his German friend Logan and hoped to get his help. Coincidentally, Logan is our customer for several years. He recommended AAK to James. When I received the hydraulic relief valve drawing sent by James and learned that he had no factory to cooperate with to make samples, I felt that it was a hot potato. After the discussion of AAK technical team, I told him that AAK has unique skills to solve the deformation of the hydraulic relief valve hole, but the production time will be at least 22 days. James had no choice but to wait patiently for the hydraulic relief valve sample of AAK. The processing of this hydraulic relief valve is still a little challenging for us. After the first sample is completed and assembled, the hydraulic relief valve hole also shows deformation under the influence of assembly force. When the assembly tightening torque is 90N·m*, the valve hole deformation reaches 0.013~0.015mm. In view of this data comparison, we will know how to improve. After 4 days, AAK sent 5 samples of hydraulic relief valves. On the second day after receiving the sample, James informed that the valve hole was not deformed and that mass production could be started. 2 weeks later, 200 hydraulic relief valves were shipped on time. AAK can effectively solve the deformation of the valve hole of the hydraulic relief valve because as early as 3 years ago, we explored a set of effective processing procedures: pre assemble the valve body first, and then place it for 2-3 days. Before honing, rough ream it with a diamond reamer, correct the roundness deviation of the valve hole caused by assembly preload and creep, and then honing. The core of this technical point is honing, most hydraulic relief valve manufacturers are stuck here. Not only to ensure the honing effect and honing efficiency, but also to reduce the impact of creep on the accuracy of the valve hole. Honing is not only a good honing equipment support, a good technician, but also a unique skill. AAK hydraulic relief valves, the valve hole does not deform, and are excellently processed and tested, you can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak306

We are troubled by a widespread paradox: the opportunities for Chinese hydraulic manifold manufacturers are decreasing. If I had built a piece of land 20 years ago, I wouldn't have established a Chinese hydraulic manifold manufacturer. 10 years ago, if I was to use the internet, I wouldn't have developed Chinese hydraulic manifold manufacturer. Last year if I bought Tesla stocks, I wouldn't pay attention to the orders of Chinese hydraulic integration manufacturer AAK anymore, This kind of frustration will persist. It is easy to infer that there is a huge opportunity now that will be envied by people 10 years from now.   In 2014, my mother came to live at my house and I planned to open a vegetable plot in the backyard to add some fun to her unfamiliar city life. But at that time, I was about to switch to a different house, and it was highly likely that the house had just been sown, and the owner had already changed, so I gave up. Who knows, the house to be changed was not negotiated at the last minute, and the time for farming was also missed. After delaying for a year, I decided to develop a vegetable field. I was just about to start, because I wanted to purchase equipment for AAK, a Chinese hydraulic manifold manufacturer. The money was not enough, so the house change was put on hold. Things are unpredictable. Due to the decline in real estate in Ningbo, the original house was on sale for 2 years. Mom was in the backyard every day, staring at the green grass that cannot be eaten or moved in a daze. 3 years later, the house was sold. But the renovation of the new house takes 2 years, and the buyer of the old house is willing to let us rent back for 2 years, which means that 5 years of vegetable planting time were wasted in the old house. For a whole of 5 years, we can all eat organic vegetables that our mother has personally grown, and our mother can dispel boredom and stretch her muscles and bones in the work of an alien land. If you stand on the other side of time, you already have the answer. As long as you stay here for a while, hurry up and open the vegetable field, you won't miss it or make mistakes. AAK hydraulic valve, from supplying domestic listed companies to focusing on overseas trade, took 3 years. AAK, from a Chinese hydraulic cartridge valve manufacturer to a Chinese hydraulic manifold manufacturer, took 5 years. In 2012, Honeywell's purchaser suggested that AAK develop hydraulic manifolds, but I shelved it due to market conflicts with the client. 1 year later, after reaching a consensus with the client, AAK, a Chinese hydraulic manifold manufacturer, was prepared to be established. However, the landlord of the factory proposed to use the factory himself, and AAK had to wait for 2 years to move to a new factory. After the new factory building of Chinese's hydraulic manifold manufacturer AAK was put into operation in 2015, it was ready to invest in equipment, but there was no money to buy Japanese equipment. During this period, I could only stare blankly at the hydraulic manifold inquiry sent by the customer, until 2017, when all the equipment was available, people were available, and orders were placed. If I were on the other side of time, I would have had the answer long ago. As long as the factory is in operation and customers have needs, I would quickly start a new project. This way, customers will not be missed, and Chinese hydraulic manifold manufacturer AAK will not be at fault.   The so-called fatalism is like this: you cannot change the future, because your change is also a part of the future. People can go back to the past, but it cannot change the course of history. If we could go back to the past, even if you choose those decisive turning points in life, such as a certain exam, choosing a major, pursuing a career, and marrying someone etc., you can make the right decision again, but your destiny in this life may still be unchangeable, as your own system structure rushes towards an irreversible fate. That's why the fate of those grand prize winners is often tragic. Of course, if you have the right attitude, interesting things will naturally find you.   Chinese hydraulic manifold manufacturer AAK, has a story, a correct attitude, and awaits interesting things.

Last week, the Spanish customer Salvador sent an inquiry for a hydraulic valve block, which was the inquiry for the 4th time, and the inquiries in the first 3 times have already been placed orders for. Salvador has been engaged in the purchase of hydraulic valve blocks for many years, and it has been successful. In March this year, they developed a large multi cylinder hydraulic cone crusher, which requires a hydraulic valve block weighing 1.5 tons. Salvador found a factory in the United States to make samples, and the equipment was successfully tested. 2 months after the promotion, there was a customer's reservation, but the price needed to be reduced by 15%. After costing, the boss asked to reduce the cost of the hydraulic valve block by 10%. Salvador contacted the manufacturer of hydraulic valve blocks in the United States, but the manufacturer refused to reduce the price. The boss asked Salvador to find a new manufacturer. Salvador contacted the all their current suppliers of the hydraulic components. None of them were able to produce the hydraulic valve blocks weighing 1.5 tons, unless to find a professional oil circuit block manufacturer. Salvador found AAK in Google and sent an email inquiry with a try attitude. I replied to him that AAK has not processed the hydraulic valve blocks of more than 1 ton, but AAK is capable of processing this hydraulic valve block, and the accuracy of the valve hole absolutely meets the IT7-8 standard, and the roughness can reach Ra0.2-0.4. After receiving the quotation from our cost accounting department, Salvador was a little surprised. After confirming that it was correct, he immediately placed order for 5 hydraulic valve blocks and paid the development cost. After 25 days, AAK delivered 5 hydraulic valve blocks. 2 weeks later, Salvador informed by email that the hole accuracy of AAK hydraulic valve block absolutely met the IT7-8 standard, and the roughness could reach Ra0.2-0.4. After it replaced the hydraulic valve blocks of the original American manufacturer, the equipment still operated normally. His boss was very happy to find a hydraulic valve block supplier benchmarking the American manufacturer, and the price was 30% lower. AAK owns the full hydrostatic heavy 5 axis gantry machining center of INNSE Berardi, Italy. The column moves and the hydrostatic guide rail is preloaded. It is suitable for processing large hydraulic valve blocks with guaranteed accuracy. The machine tool can be equipped with a fixed or working beam (W- axis), and the special detection device can compensate the thermal drift, so that the tool can have high operation accuracy. The coordinate axis runs on the preloaded hydrostatic guide rail to ensure maximum rigidity and balance of operation. AAK hydraulic valve blocks, 5 axis gantry machining center, welcome to have a try! https://www.aakindustry.com/info-d , etail/hydraulic-valve-blocks-aak305

Kaka is from Brazil. When he left a message and his signature on AAK hydraulic valve website, I thought of Kaka playing football. He encountered confusion about the service life of the locally purchased hydraulic cartridge solenoid valve. Their hydraulic power unit requires the use of a hydraulic cartridge solenoid valve benchmarking HydraForce, and he purchased the existing copy stocks from a local hydraulic valve manufacturer in Brazil. 6 months later, there were complaints about severe wear and leakage of the cartridge solenoid valve body. The original cartridge solenoid valve manufacturer said that due to poor working conditions, the only solution is to replace the valves with new ones. But it wasn't long before the old problem recurred. The customer was very dissatisfied and requested that the service life of the cartridge solenoid valve be at least 1 year, but the original manufacturer did not cooperate, making Kaka anxious. Kaka discovered AAK hydraulic valve on Google and left a message asking: Can AAK ensure that the service life of the cartridge solenoid valve is at least 1 year under high friction and high-frequency use? Especially the cartridge solenoid valve body needs to be wear-resistant. Upon seeing this message, I speculated that the selection of materials for the original cartridge solenoid valve was not targeted and only followed the industry standards. After communication, it was learned that he encountered the dilemma of the valves not being wear-resistant when purchasing from local hydraulic valve manufacturer in Brazil. This model is a HydraForce standard part and AAK have it in stock. But for his working conditions, we cannot simply use 40Cr alloy steel to produce the body of this cartridge solenoid valve. Kaka may have realized that I came to the point and requested AAK to make 30 samples of the cartridge solenoid valves first. 2 weeks later, AAK sent out the cartridge solenoid valve samples. Last week, Kaka placed a PO for 360 cartridge solenoid valves, which indicates that AAK hydraulic cartridge solenoid valve has passed the test with a service life of over 1 year. After confirming the delivery time for the first order, he told me that the customer is very satisfied with AAK cartridge solenoid valve, which is not only wear-resistant, but also leak free, and has no abnormalities within 1 year. We have chosen high-strength alloy steel instead of the industry's 40Cr alloy steel to produce the body of this cartridge solenoid valve. The surface treatment of steel adopts electromagnetic induction heating, and the surface oxidation and decarburization of the workpiece are relatively light. The surface hardening layer is easy to control, and the hardness and toughness are high, increased by more than 30% compared to conventional heat treatment processes. Especially during induction heating surface quenching, the workpiece generates internal stress and improves its fatigue resistance. Therefore, the wear resistance of high-strength alloy steel treated in this way is 8-10 times that of the original 40Cr alloy steel. In the wear-resistant aspect, AAK cartridge solenoid valve can be used for 3 years without any trouble. AAK hydraulic cartridge solenoid valve, wear-resistant for 3 years without any trouble, you can also give it a try!

In any manufacturing industry, there is no tomorrow if without innovation. AAK Hydraulic Valve put forward the idea of "pioneering innovation" at the technical internal meeting in 2022. When it comes to technological innovation, everyone will think of chips first. In fact, every industry has technology and innovation. Innovative technology has never been the purpose. The user is the purpose. It was, will be and will always be. Only by focusing hearts on users, and eyes on technology can we make "pioneering innovation" products from the bottom logic. What is "pioneering innovation"? People imitate bird flight and make bigger and more suitable wings for humans. Is it innovation? Of course. But, after all, it can't fly to the sky. Can't fly from Shanghai to Beijing with flashing wings. The end of imitation is to be the other side. But as a result, we can only approach the other side. Not even close. What can we do? Don't observe how the bird can fly to the sky, but gain insight into why it can fly to the sky. Then, man found the essential law of flight that the bird itself did not know: aerodynamics, and finally invented the airplane. This is pioneering innovation. It's interesting and reasonable. Asking, how can hydraulic valves, hydraulic manifolds and hydraulic valve blocks be "pioneering innovation"? Are these things too hard to "open up"? Of course, it can. Just like the essence of an airplane flying into the sky is not wings, but aerodynamics. Wings are just one way. The essence of hydraulics is not valve, manifold or block, but the fluid control of "flow, pressure and direction". From these 3 points, innovation will never end. The lighting company said that we are not a company that designs "lamps", but a company that designs "lights". Lamp is not the essence, but light. The shape, size and material of lamps should not be the subject of research by lamp companies; Luminaire companies should study color temperature, hue and light and shadow coordination. Lamp companies should not see the lamps, but light. The same is true for hydraulic valves. AAK is not a hydraulic valve company. Our future is a fluid flow control technology company, a fluid pressure control technology company, and a fluid directional control technology company. Jobs said that market research often can only reflect the current situation, not predict the future. The key is to start from the heart and make good products. Why? Because the needs of users have never changed. The user demand of the hydraulic industry is how to control the hydraulic system of the equipment more quickly, stably and accurately. No matter how much of research, it will not change. It hasn't changed for thousands of years. If you ask user how he expect to improve the hydraulic valves, the hydraulic manifolds and the valve blocks, it is not a survey, but regard the user as a "product manager". The user does not know how to improve these hydraulic components, nor does he need to know. These are the responsibilities of our hydraulic valve manufacturers. AAK Hydraulic Valve, keeps paying attention to the progress of science and technology, starting from the essence and opening up innovation. https://www.aakindustry.com/inf , o-detail/hydraulic-valve-manufacturers-aak492

Tim, from the United States, is a hydraulic valve customer that AAK has cooperated with for 5 years. They mainly sell logistics transmission equipment. On Monday, his sales manager sent me an email. It was the first time I received an email from their sales department. Subject of the email: how to do the promotion content? He said that he was surprised to see that AAK has posted the content of hydraulic valves every day. They have more than 100 hydraulic valve suppliers, and none of them can update the promotion content every day. This requires not only time, patience, but also professionalism. I told him that AAK hydraulic valves do it from 3 points: First, try to update every day This is a kind of determination and professionalism. Some people say that I can write my article today and shoot the video tomorrow if I want, OK? If it's personal preference, of course. But if it's a job, or even a career, it's best not to do so randomly. Look at those big online bloggers. None of them dare to stop. Because once it stops, the users may leave. Posting content and ensuring the frequency of updates also provide a kind of certainty. Using daily updates to exchange the cognition and habits of hydraulic valve users and convey a kind of value. Second, ensure high quality Because in the era of Internet, there is too much information and too miscellaneous content to see, and users will forget your content 7 days later. But this should not be an excuse to make bad content. On the contrary, only high-quality content can gain the trust of hydraulic valve users. Users will be impressed. It turns out that this hydraulic valve manufacturer is like this, so I'll continue to have a look. In this way, he is willing to give you time extravagantly. Therefore, in order to improve the content of hydraulic valves, we must constantly improve ourselves. The content, to some extent, is to attack mosquitoes with cannon. Only in this way can high-quality hydraulic valve content be guaranteed. Third, the spirit of long-termism This point is easy to understand. Be a friend of time. Sometimes it is not time that abandons us, but we abandon time. Anyone who has done content knows that this is a craft that needs to be practiced slowly. It also needs mental strength, which needs to be grinded slowly. No matter how the platform changes, it doesn't matter. Because all changes ultimately encourage those who are willing to do content for a long time. If there is a long-term spirit, all changes will be good. AAK hydraulic valves content, in giving customers value, I also keep thinking. I don't know if what I think is right, but I vaguely feel that maybe it is. On the surface, we provide these 3 values: First, professional knowledge. Every article is delivered to readers with knowledge value. This knowledge should be professional, insightful and able to solve problems. Second, credit. Because of the influence of AAK hydraulic valves on the Internet, we have corresponding credit. When we say that the hydraulic valve is good, the management mode and the equipment are good, we are endorsing with credit. Third, transmission. Expect to let more people see the pain points and chaos of the hydraulic valve industry, so that people who need hydraulic valves do not take detours. I often say to my colleagues that if we only think about this, maybe we can't do better. Don't others have these 3 values? Other hydraulic valve manufacturers may also provide them and better than ours. So, what is it that others can't learn and can't copy? Maybe it's our ability to see things clearly, speak clearly and speak in vernacular. In fact, most people are doing complex work, and we all hope that professionals can "speak human words", but in reality, it is difficult to summarize a sentence in a simple sentence. Experts' conventional expression: 871 mg of cholesterol per 100 grams of dried squid. Then I'll translate it into colloquialism: one bite of squid is equal to 20 bites of fat meat. I think, for people who lose weight, after listening to the experts' words, maybe they can't help eating squid, but seeing my vernacular, maybe they put it down silently. Finally, less than 1% of hydraulic valve manufacturers can achieve daily updates. AAK hydraulic valves, with 100% persistence to do 1% of things, the right way, never afraid of far away. https://www.aakindustry.com/info-deta , il/hydraulic-valves-aak304

Jose comes from a hydraulic equipment manufacturing company in Brazil and has been purchasing for many years. In the first half of last year, he was foxed by a hydraulic relief valve with high requirements. AAK took more than 3 months to make samples of the hydraulic relief valves for 6 times, helped turn Jose's abortion order into a big one. At the beginning of last year, Jose’s company received an order for a high- precision hydraulic full-automatic wrench, and customer needed to place a large order after the trial sample order. Jose knows that the wrench function is largely determined by the accuracy and flow control of the hydraulic relief valves. After discussing with more than 10 hydraulic cartridge valve manufacturers, he chose 3 of them to make samples, but the results showed that none of the hydraulic relief valve samples can meet the requirements of valve hole accuracy tolerance of 0.8μm, and the flow control is unstable. Jose asked them to make samples again, but only one of them was willing to try. 1 month later, the accuracy was still not up to standard. The customer was very dissatisfied that almost 3 months passed, the wrench sample was still not available and cancelled the order. The boss asked Jose to continue to look for the hydraulic relief valve manufacturers and develop the samples first whether the customer cancelled the order or not. Jose found AAK on Google and left a message on AAK website: is AAK willing to develop a hydraulic relief valve that was failed in more than 10 factories? As soon as I read this message, which is a little "stimulating", I became motivated. After receiving his hydraulic relief valve drawing, I knew why so many factories couldn't make it. The accuracy and stability requirements of the hydraulic relief valve are 3 times that of the standard parts. I replied to him: AAK is 90% sure to be successful, but can't determine the development time, maybe 3 months. I think most customers will basically give up AAK after receiving such an answer, but 3 days later, AAK received the development fee he paid. I think this is Jose's trust in AAK. I also told him that if AAK development failed, I was willing to refund 100% of the development fee, and I used trust to repay his trust in me. After trying samples for 6 times in more than 3 months, AAK sent the hydraulic relief valve samples finally after they passed the test. 2 weeks later, Jose said that the testing on the wrench sample was also successful. If the customer is satisfied with the trial, there will be a large order for them. Jose learned our persistence in the sample, and was impressed by AAK’s 3 advantages: 1.AAK has cooperated with 3 Fortune 500 enterprises to develop more than 200 non-standard hydraulic relief valves, and all of them have been successful. 2.AAK's German GILDEMEISTER ultra-high precision machine tool is specially used for hydraulic relief valves with high precision requirements, ensuring the machining accuracy of 0.5-0.8μm. 3.AAK engineer has nail spirit, no matter how long the development takes, if it is not successful, it will not stop. AAK hydraulic relief valves, high precision, long service life, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak303

Why did AAK extend to hydraulic manifold manufacturer in 2015? This issue, like most entrepreneurial hydraulic manifold manufacturers, although each has its own complexity, in the final analysis, it is actually a very simple matter. Entrepreneurs cannot avoid 3 simple questions: what kind of transactions do you plan to do for the hydraulic manifold manufacturer you founded? Why are you? How do hydraulic manifold manufacturers make money? What kind of transaction are hydraulic manifold manufacturers planning to do? The money earned by hydraulic manifold manufacturers is essentially earned in exchange. How can I exchange this money? There are 3 roads.   The first way: Since you want a hydraulic manifold manufacturer to make money, think about how to give someone else 80 yuan of hydraulic manifold and then exchange it for 100 yuan. This logic is correct, but most hydraulic manifold manufacturers will deviate and start controlling production costs, even cutting corners. This creates a problem: customers will suffer losses. Once customers have suffered a loss, there will be no second business. Such hydraulic manifold manufacturers are not doing much and cannot continue to do so.   The second way is to deliver a hydraulic manifold of 100 yuan to someone else and exchange it for 100 yuan back. To take this path and create profit margins, one must work hard to reduce costs and increase efficiency. It is very practical. But it's very aggrieved. The customer didn't suffer, but he didn't think it was worth it either. Further discounts may be required for the next purchase from hydraulic manifold manufacturers. The third way: Give someone a hydraulic manifold of 100 yuan, and then get back 80 yuan from them. So I'm not at a loss? A transaction that benefits all parties involved, making everyone willing to trade again next time. Once the transaction structure undergoes such iterations, it is possible to open up new value spaces. It's so difficult for hydraulic manifold manufacturers to make money, why are you the one who survived? In the early days of hydraulic manifold manufacturer AAK, I began to ask myself: Do you want to do it? If you do it, why can you succeed and why am I? After trying a lot and exploring for a long time, we found an answer. Perhaps AAK is not the most capitalized or responsive, but at least we agree and have confidence in working in one direction: clarifying complex hydraulic manifold customer cases, focusing on hydraulic manifold manufacturers themselves, and persistently striving for manufacturing quality. Help our clients save energy and time, and avoid detours. After determining this direction, we consider it as our core competency to exercise, and all the reviews are centered around it. All efforts are made to answer: Why are you. Although some hydraulic manifold manufacturers are studying AAK’s copywriting, AAK's tweet structure, and even some hydraulic manifold manufacturers are studying our advertising slogans, they just haven't studied the core of AAK, let alone its own core competencies.   The most profitable way is written in the criminal law, which includes pitfalls, deception, abduction, and deception. The root cause of these things is that they do not have enough value to exchange with others. This kind of transaction is the simplest but also the most difficult. A technical hydraulic manifold manufacturer tests your ability to do things well and solidly. But at the same time, it also tests your eyes to see the key values of the industry. AAK hydraulic manifold manufacturer, don't let people suffer, let people benefit more. Then, AAK will also benefit from it. The basic logic behind the establishment of a hydraulic manifold manufacturer is actually a very simple matter. A modest AAK person, doing modest things. AAK HYDRAULIC CARTRIDGE VALVES (672) 2023-09-16 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers-aak672

Miguel is from a hydraulic equipment company in Brazil. He began to purchase hydraulic components in China 3 years ago, and it was successful. At the beginning of last year, the hydraulic flow control valves he purchased encountered problem and almost suffered a claim. Since using AAK hydraulic flow control valves to replace, he knows that there are also hydraulic valve manufacturers in China that have benchmarked the quality of German manufacturers. Miguel company sold a hydraulic unit, which was used in wind power generation equipment near the sea. Half a year later, the customer complained that the valve body of the hydraulic flow control valve was seriously corroded and stuck, leading to the strike of the wind turbine generator. According to the factory feedback of the original hydraulic flow control valves, the corrosion of the valve body is caused by the objective marine climate, the hydraulic flow control valves can only be replaced. Miguel realized that replacing it within 6 months was not only expensive for after-sales, but also not necessarily acceptable to the customer. He purchased the hydraulic flow control valves from Germany to replace it. At the same time, he asked some new hydraulic valve manufacturers to make samples and required that the hydraulic flow control valves to be guaranteed for 12 months or more in the corrosive environment near the sea. Most manufacturers gave up, and only two were willing to test samples, including AAK. After 40 days, AAK shipped the trial order of 30 hydraulic flow control valves. There has been no email from Miguel since the trial order was delivered. 15 months later, that is, last week, Miguel suddenly emailed us to purchase 800 hydraulic flow control valves. After communication, we learned that they were very satisfied with AAK hydraulic flow control valve samples delivered 1 year ago. The samples from another factory were corroded in 10 months, while AAK’s were still fine after 15 months. This service life was benchmarked to the hydraulic flow control valves purchased from German manufacturers, but the price of AAK was 30% cheaper, so they directly placed a big order. AAK hydraulic flow control valves can be used in highly corrosive marine environment for 15 months without damage. The key lies in 3 points, which most domestic hydraulic valve manufacturers cannot do: 1. In terms of material, 3Cr3Mo3W2V hot working die steel is selected for the valve body, and its mechanical stress is optimized by at least 50% compared with other steels. After personalized heat treatment, the hardness, strength and corrosion resistance of the material are more than doubled. 2. In terms of surface treatment, zinc nickel alloy coating is adopted, and the corrosion resistance of the valve body is improved again. Its corrosion resistance is more than 10 times higher than that of ordinary zinc plating and nickel plating processes, which can ensure that there is no red rust after neutral salt spray test for more than 1500 hours. 3. In terms of detection, AAK has SH-90 salt spray testing machine, which tests the valve body according to the GB/T2423.17 test standard to ensure that any surface of the valve body meets the salt spray test standard. AAK hydraulic flow control valves are safe to use near the sea, and durable under high pressure and high frequency use. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak302

Alex, an old friend from Brazil who has worked with AAK for 5 years, sent me an email last month, asking me to help his new colleague Marvin to make samples for a hydraulic cartridge directional control valve and to work overtime urgently. It was learned that Marvin just joined the industry for half a year. The coaxiality accuracy of the hydraulic cartridge directional control valve purchased by Marvin from the local cartridge valve manufacturer in Brazil was not up to the standard, which led to the customer's complaint about the unstable operation of the hydraulic winch. Their engineer detected that the coaxiality error of the hydraulic cartridge directional control valve was 0.004mm, which caused the pressure in the fitting gap between the valve hole and the valve spool to be unbalanced, it must be replaced, but the original manufacturer gave up. The customer has been pushing for progress. Marvin has no direction, so he asked Alex to help. According to the drawing of the hydraulic cartridge directional control valve sent by Marvin, although it is difficult for the coaxiality error to be less than 0.002mm, our engineers have the means and are willing to work overtime to deal with it. AAK treats regular customers with the green light as much as possible. After 25 days, 12 samples of hydraulic cartridge directional control valves were sent out. Last week, Marvin emailed that AAK hydraulic cartridge directional control valves had been installed on several abnormal hydraulic winches, and the customer was satisfied with his after-sales service. He was asking the boss whether he needed to replace all the hydraulic cartridge directional control valves in this batch of hydraulic winches, and asked me to ensure the stability of the quality. I told him that for this model, AAK quality may not be the best, but the most stable. There would be no cases that the coaxiality error is 0.004mm for one moment, the fitting clearance between valve hole and valve spool is 0.002mm for another moment. There would not be the case that the fitting clearance between valve hole and valve spool, is big or small. AAK hydraulic cartridge directional control valve, stable coaxiality error, and stable sealing of valve body and valve spool, fundamentally ensure the working stability of the hydraulic winch, which mainly comes from 3 aspects: 1. Technically, the machining process of the valve hole of the hydraulic cartridge directional control valve adopts 6 procedures, including drilling, rough boring, semi fine boring, fine boring, reaming and honing. Most cartridge valve manufacturers do not have semi fine boring procedure, and only 5 procedures. 2. On the equipment, the valve hole is processed by the horizontal machining center imported from Japan, which is mainly used for military products processing. At the same time, diamond reamers are equipped for reaming to ensure the surface roughness, cylindricity and roundness error of the valve hole. These precision parameters are controllable and stable. 3. In terms of detection, the improved CMM is used to check, and the coaxiality error is strictly controlled within 0.002mm.

Achilleus is from Greece. In the second half of last year, a high-pressure hydraulic winch sold by his company for less than 3 months, was unable to rise and fell suddenly during construction, which almost caused a safety accident. The on-site investigation found that an oil pipe in the hydraulic system was broken and leaked oil. After the oil pipe was replaced, the equipment was restored. But 2 months later, similar problems repeated. The customer couldn't stand this series of problems and complained to the boss. The boss was angry and asked the technical team to solve it completely within 1 month. Achilleus also felt the pressure of the boss and contacted several factories to inquire, but there was no result. Achilleus saw AAK on Google and sent an email asking with a try attitude, and attached the hydraulic schematic diagram. After analysis, AAK engineers found that the probable reason was that the oil pipe burst was caused by the energy conflict between the hydraulic counterbalance valves in the system and the flow control of the system. We informed Achilleus of the analysis results the next day and recommended that AAK make the samples directly. We will redesign the hydraulic counterbalance valve according to the energy principle of the hydraulic system. 3 days later, Achilleus placed the sample order for 10 hydraulic counterbalance valves and also paid the development cost. After 45 days, AAK sent the samples. Last week, Achilleus sent an email to express his thanks. After using the hydraulic counterbalance valves redesigned by AAK, the hydraulic winch has been running stably for half a year, and the customer is also very satisfied. The boss praised him, too. Their engineers admire the design ability of AAK and suggest Achilleus to take AAK as the preferred supplier of hydraulic counterbalance valves. AAK unique designed hydraulic counterbalance valves, with triple safety protection, customers no longer worry about the burst of the oil pipeline of the hydraulic system. 1. AAK changed the flow control groove of the hydraulic counterbalance valve, and redesigned small flow control groove. The maximum working pressure can reach 420bar, realizing zero leakage load maintenance. Even if the oil pipeline bursts, the load will not be out of control. 2. The working mode of the hydraulic counterbalance valve designed by AAK is similar to a two position flow controller with compensation, which can realize the curve of different forms of flow decreasing with the increase of load pressure, so that the control tank with small flow can realize the optimization of control. 3. According to the characteristics of this winch hydraulic system, the hydraulic counterbalance valve designed by AAK has different damping combination configurations, so as to ensure the stability of the winch hydraulic system. AAK hydraulic counterbalance valves, unique design, welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valves-aak301

Yobachi, from Kenya, has not been working for a long time as a purchaser, and encountered difficulties in the hydraulic directional control cartridge valve. After 6 months of use, their hydraulic power unit has unstable operation. During after-sales checking, it was judged that that the main seal of the hydraulic directional control cartridge valve is worn, causing leakage and equipment failure. However, the hydraulic directional control cartridge valve manufacturer said that it had been nearly 1 year since the shipment, and he needed to purchase new ones again. Yobachi explained that taking the time on the delivery, transportation, assembly, equipment commissioning and inventory into account, the actual service life of this batch of hydraulic directional control cartridge valves was only 6 months. The boss was not satisfied that Yobachi had found an unreliable manufacturer. He had to re-purchase the hydraulic directional control cartridge valves with a service life of more than 1 year without leakage. Yobachi was under pressure. Yobachi left a message on our website: 1. I browsed the AAK cartridge valve website on Google. 2. Can AAK hydraulic directional control cartridge valve have zero leakage? And the service life is more than 1 year? 3. What is the time and cost of customizing the hydraulic directional control cartridge valve? This is the first time that AAK received an inquiry from Kenya about hydraulic cartridge valves. I was a little cautious. After communication, it was learned that he had met with an unreliable hydraulic cartridge valve manufacturer, which made him very passive with the boss and customers. According to the system hydraulic schematic diagram and the original drawing of the hydraulic directional control cartridge valve provided by him, after the analysis, AAK engineers found that it is not difficult to make this hydraulic directional control cartridge valve as zero leakage. Yobachi seemed a little unconvinced. I told him that in 2022, AAK customized 67 non-standard hydraulic cartridge valves for customers, and made samples of total 112 models of cartridge valves for new and old customers. Till now, there are no quality complaints. After 7 days, Yobachi requested AAK to make samples. After 40 days, AAK sent 20 samples of hydraulic directional control cartridge valves. 3 weeks later, Yobachi only told us that the equipment installed with AAK hydraulic directional control cartridge valve operated stably, and there was no further news. On the first working day after our CNY holiday, he sent an order for 380 hydraulic directional control cartridge valves. He said that AAK hydraulic directional control cartridge valve has been in use for more than 1 year, without leakage, and the equipment performance is more stable. The boss asked him to purchase in batches. The leakage of the original hydraulic directional control cartridge valve is mainly caused by the wear of the main seal, which leads to the leakage of the pilot hole. The cover plate, valve spool, valve cage, O-ring, guide rod and valve body of the pilot hole are all tricky. It is not difficult to make it zero leakage, AAK improved the original structure of the hydraulic directional control cartridge valve from 3 aspects: 1. The cover plate and valve body are connected by screws, the valve cage is inserted in the valve body, the valve spool is installed in the valve cage, the valve spool is located under the cover plate, and the bottom surface of the valve spool cavity is equipped with a return spring. 2. The inner wall of the valve spool is installed with a sealing ring that can prevent the leakage of the pilot port. The main seal adopts a soft and hard composite seal structure. The O-ring is installed on the valve spool guide cylinder, and the O-ring prevents the oil from flowing back to the tank from the pilot hole. 3. The main seal of the hydraulic directional control cartridge valve adopts a soft and hard composite seal structure to prevent leakage at the pilot hole and the main seal.
