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.

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.

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. AAK hydraulic cartridge directional control valve is reliable, and you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-directional-control-valves- aak420

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. AAK hydraulic directional control cartridge valve, no leakage, you can also try it! https://www.aakindustry.com/info-de , tail/directional-control-cartridge-valves- aak4 , 91

Titan comes from Türkiye, and does not purchase many hydraulic cartridge pressure control valves from AAK. In February of this year, he had an inquiry for a model of HydraForce hydraulic cartridge pressure control valve PS10-36. Titan felt that the price of AAK was high and chose another hydraulic cartridge valve manufacturer in Ningbo China. Last month, he came to me again for the same model PS10-36 and needed 400 pcs. After communication, it was learned that last time, the delivery of the hydraulic cartridge pressure control valves from the original manufacturer was delayed by 2 weeks, which made him very passive with the customer. The quantity of the hydraulic cartridge pressure control valves has been increased this time, and he is not sure about the delivery time of the original manufacturer. The 400 pcs of hydraulic cartridge pressure control valves benchmarking HydraForce PS10-36 needs to be delivered within 20 days. From material procurement to shipment, there should be no more than 5 hydraulic cartridge valve manufacturers in Ningbo that can complete within 20 days, unless the manufacturer has more than 300 pcs of hydraulic cartridge pressure control valves in stock, but there are not many manufacturers in Ningbo that dare to produce large quantities of inventory. I told Titan that AAK can complete the delivery of 400 pcs of hydraulic pressure control valves PS10-36 in 20 days, because of 2 advantages. Firstly, there is some inventory in the warehouse, and secondly, AAK's unmanned workshop produces this model, which can increase the production efficiency by more than 40% compared to the original manufacturer. Yesterday, the 400 pcs of hydraulic cartridge pressure control valves were delivered to Titan on time. Without comparison, there is no harm. I believe that the uniqueness of AAK this time will stimulate Titan to give AAK more and more inquiries for hydraulic cartridge pressure control valves. For this hydraulic cartridge pressure control valve PS10-36, AAK are equipped with a fully automatic CNC machine tool from Japan Tsugami, along with self- developed fixtures, to achieve an unmanned production process. Its servo drive and multi axis linkage ensure accuracy and avoid human error. Only the program settings need to be in place, but the equipment manual cannot be mechanically copied. Our technicians set the processing parameters according to the engineer's programming, implant the valve cage into the bracket, and after starting the equipment, there is no need for manual labor. The clamping arm automatically clamps the valve cage into the machine tool fixture, and the machine tool starts working. As long as there is a blank part on the bracket, processing will not stop. Most hydraulic cartridge valve manufacturer rely on manual clamping, resulting in slow processing and human error in accuracy. 1. AAK adopts Japanese military industrial CNC machining centers, and I don't know which hydraulic pressure control valve manufacturers in Ningbo have more efficient equipment than this. 2. The quality is equivalent to HydraForce and is stable, and AAK dares to make inventory levels that its peers dare not do. 3. Unmanned production workshop, with an efficiency 40% higher than most hydraulic pressure control valve manufacturers in Ningbo. AAK hydraulic cartridge pressure control valve, with a delivery time of 40% faster, reliable and stable quality, welcome to give it a try!

Kuplin is from a Russian hydraulic equipment manufacturing company, he has purchased hydraulic valve blocks from China for a long time, which is also relatively smooth. However, a hydraulic valve block he purchased at the end of last year put him into a hard situation. A batch of hydraulic climbing cars sold by their company were complained by customers. During the routine maintenance of the hydraulic system, several cartridge valves on several equipment cannot be taken down, the nose end is stuck in the socket of the hydraulic valve blocks, and there is a small amount of leakage around the socket. The hydraulic valve block manufacturer replied that when processing the hydraulic valve blocks, the technician processed the nose end of the socket into a conical surface, which made it easy to install and difficult to take down, and also affected the seal, resulting in a small amount of leakage. The hydraulic valve block can be replaced free of charge, but no one will bear the loss of those hydraulic cartridge valves that cannot be disassembled. After the boss learned that, he asked Kuplin to find a new manufacturer of hydraulic valve blocks. Kuplin contacted more than 10 new factories and required that there was no abnormality in the processing of valve holes of each hydraulic valve block. After a round, he did not find any suitable supplier of hydraulic valve blocks. Kuplin began to worry. By chance, Kuplin met his old friend Petrov and learned about AAK's ability to process hydraulic valve blocks during the communicating with each other. After several communications with him, AAK started to make samples directly. 1 month later, AAK sent the hydraulic valve blocks. Petrov informed by email that their engineer specially inspected each valve hole, and the tolerance was controlled 100% without deviation. He wanted to know how AAK achieved it? AAK hydraulic valve block has no deviation from the processing of the installation socket, is due to 3 strict points: 1. For tool inspection, it is in the charge of a specially assigned person, who regularly inspects each tool equipped in each machining center to confirm whether there are cuts or cracks on the leading edge of the tool, so as to avoid the problem of machining finish caused by tool wear or damage. 2. Clean the cutter. AAK uses a diamond file to remove the debris of the cutter material and ensure that the positioning shoulder on the reamer remains sharp. AAK will check the size of the ground tool based on the tool positioning shoulder to ensure that the depth and diameter meet the processing requirements. 3. After machining, use diameter gauge and thread gauge to check the dimensional accuracy according to the requirements of the socket drawing, and carry out the final socket dimensional check. Especially, the nose part of the cartridge valve socket will be measured from the front end of the nose to the supporting end of the nose, so as to ensure that there is no cone at the nose. AAK hydraulic valve block is easy to install and take down without deviation, and 100% free of burrs.
