The essence of Hydraulic Valves, Blocks & Manifolds

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

AAK uses 3 points to promote hydraulic valve content and transmit 3 values

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

AAK Hydraulic Relief Valves High Accuracy and Stability

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

AAK Hydraulic Manifold Manufacturer 3 Thoughts about Ways to Make Money

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 Flow Control Valves Over 1 Year Service Life Near the Sea

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.

AAK Hydraulic Cartridge Directional Control Valve of High Stability

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

AAK hydraulic counterbalance valve with triple safety protection

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

AAK Hydraulic Directional Control Cartridge Valve Zero Leakage

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

AAK Hydraulic Pressure Control Valve PS10-36 40% Faster Delilvery

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!

AAK hydraulic valve block socket with no deviation, Kuplin admired

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. You are welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak300

AAK Hydraulic Valve Block Blind Hole Processing Unique Skills

Palencia is from Spain and has little cooperation with AAK. Some time ago, he emailed us to discuss about the blind hole of hydraulic valve blocks. After several rounds of email communication, it was learned that in the second half of last year, Palencia tried samples with more than 10 hydraulic valve manufacturers because the blind hole quality of the hydraulic valve block was not up to standard. The samples of the hydraulic valve blocks either had a bell mouth in the blind hole, or the surface roughness of the hole wall was not up to standard. It wasted him 4 weeks before and after, moreover, the development fees paid were not refund, which made him very depressed. According to the drawing of hydraulic valve block provided by Palencia, the processing difficulties are mainly concentrated in the blind hole. The processing hole diameter of this hydraulic valve block is small, and the depth is more than 40mm. Only the cutter bar with slender shaft can be used, but the cutter can not all pass through the hole, resulting in easy deformation of the inner hole diameter and axial taper and ovality. In this way, the bell mouth is easy to appear at the hole depth of 10 ~ 20mm, and the surface roughness of the hole wall can not be guaranteed, too. AAK innovated the technology 3 years ago for the difficulties of blind hole processing of hydraulic valve blocks. I directly replied to Palencia that this is a difficult processing, but it is not difficult for AAK. You can directly test the order. If our goods does not meet the requirements of the drawings, the development fee can be refund. 4 weeks later, AAK sent 5 samples of hydraulic valve blocks. 2 months later, Palencia placed the annual order of 600 hydraulic valve blocks, with goods shipped every 2 months. Their engineers were surprised why AAK succeeded in making samples at one time, while all other hydraulic valve manufacturers failed previously? For the processing of small and deep blind holes in the hydraulic valve blocks, most hydraulic valve manufacturers cannot meet the high-precision requirements, while AAK has a high-precision CNC processing center imported from Switzerland, and adopts the technology of extruding holes with a patented bladed extruding knife independently developed by AAK. And this processing method has 3 advantages. Most hydraulic valve manufacturers are difficult to master this technical detail in operation, but AAK mastered it 3 years ago. 1.The blind hole of the hydraulic valve block adopts a bladed extruding knife. Through longitudinal feeding, a moderate extruding force is applied to the workpiece surface, and then through the rotation of the knife or workpiece, the height difference between the crest and trough of the knife mark is reduced, and the surface roughness is optimized. 2.During the processing, the hole surface produces slight cold work hardening, which improves the physical properties of the blind hole surface and improves the hardness and wear resistance of the blind hole surface. 3.After machining, the roughness of the hole can reach Ra value of 0.8 ~ 0.4μm. The ovality circle error is 0.01 ~ 0.02mm, the taper error is 0.01 ~ 0.025mm, and the dimensional accuracy of the hole can be controlled within 0.01mm. AAK hydraulic valve blocks, blind hole processing with unique skills, and also with 3 types of pressure test standards to guarantee quality, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-299

AAK hydraulic directional control valves with mirror grinding, no jamming

Fabian from the Netherlands left a message on AAK website last month: what is the reason for the hydraulic direction control valves stuck? In general, the processing roughness of valve spool and valve hole is poor, or it is caused by radial unbalanced hydraulic pressure caused by inconsistent coaxiality. AAK adopts mirror grinding for the finishing of valve spool and valve hole, and the surface roughness can reach AO=Ra0.08μm, which is more than 10 times that of its peers. According to Fabian, in the second half of last year, the hydraulic directional control valves of the trial order got stuck, which made them very anxious. Thia hydraulic directional control valve is used on the hydraulic power unit. After the equipment is commissioned and operated continuously for 48 hours, the pressure supply of the equipment is abnormal. The engineer disassembled and found that the contact surface between the valve spool and the valve hole of the hydraulic directional control valve is too rough, so the hydraulic directional control valve needs to be replaced, and the surface roughness is required to reach AO=Ra0.5μm or below. The original manufacturer fed back that the roughness of valve spool and valve hole Ra1.0μm was their limit. Fabian was very depressed and had to find a new manufacturer of hydraulic directional control valve. Fabian contacted more than 10 factories, and none of them confirmed that the RA of the contact surface between the spool and the valve hole of the hydraulic direction control valve can be controlled at 0.5μm. They also told that it was not necessary to control the Ra value when it was stuck, and Fabian would have no direction. He found AAK Hydraulic Valves and left a message to ask the reason why the hydraulic directional control valve was stuck. According to Fabian's description and the drawing of this hydraulic directional control valve, I think their engineers' new requirements for Ra value are reasonable. AAK is able to control Ra value well. We recommended that Fabian directly test the order. If our Ra value does not meet the standard or the hydraulic directional control valve is stuck, we can refund it in full. After 35 days, AAK sent 10 samples of hydraulic directional control valves. Two weeks later, Fabian informed by email that no abnormality was found during the commissioning of the AAK hydraulic directional control valves. Their engineers specially detected the Ra value of the contact surface between the valve spool and the valve hole, and were surprised that it is Ra0.08μm, which is more than 10 times more accurate than that of peers, and more than 6 times what they require. The surface finish of the valve spool and valve hole directly determines the flexibility of the hydraulic direction control valve, and most hydraulic valve manufacturers tend to ignore this small detail in the processing process. AAK hydraulic direction control valve spool and valve hole are precision machined with the NP520X-F full-automatic universal grinder of Japan's Long Island Precision grinding machine, which can achieve μ level feed mirror grinding, the surface of the machined valve spool is like a mirror. AAK hydraulic directional control valves, no jamming, you can also have a small try! https://www.aakindustry.com/info-d , etail/hydraulic-directional-control-valves- aak , 298

AAK Hydraulic Sequence Valve View about Payment

Last month, a Brazilian hydraulic valve customer informed me that due to domestic political reasons, they had stopped importing hydraulic valves. I was a bit surprised at the time, as he had been purchasing hydraulic Sequence Valves from AAK. Two weeks later, it was learned that this hydraulic valve customer had applied for bankruptcy. Fortunately, the hydraulic Sequence Valves supplied by AAK are all prepaid. It was heard that the other two hydraulic valve manufacturers in Ningbo have over 70,000 US Dollars of payment for hydraulic Sequence Valves not recovered. Lucio and I met 3 years ago. After purchasing hydraulic Sequence Valves from AAK for a period of time, he asked me to accept a TT NET 60 days of payment terms, but I politely declined, then he moved a portion of the hydraulic Sequence Valve orders to peers in Ningbo, with several high-precision hydraulic Sequence Valves continuing to be purchased from AAK. When Lucio initially discussed the payment terms with me, he confidently said, "I won't owe you any money, even if the finance department runs out of money, I will pay you for the hydraulic Sequence Valves”. I hesitated a bit, but on second thought, what kind of guarantee should I use? After all, this is not his personal business, but the company's business. Last week, my aunt came to borrow money from my mother because my cousin borrowed an online loan. If she doesn't repay it, there will be big trouble. My aunt hopes her elder sister can lend 500,000 yuan to her. My aunt cried and said, 'I want to save my son even I bankrupt myself. '! I know my cousin's addiction to gambling, which is a bottomless pit. 2 years ago, my aunt had already repaid my cousin's gambling debt of over 200,000 yuan. Now, his behavior repeated again and borrowed online loan unexpectedly, and all his bank cards have been overdrawn, creating a hole of 500,000 yuan. My mother doesn't have much money in her hands. Seeing that her younger sister is pitiful, she wants me to help my cousin. My aunt asked me to believe in her. She will return money definitely. My mother certainly believes in her sister and is willing to guarantee this loan. I asked my aunt when to return it? Aunt said: 5 years at most! I answered: Of course I believe in you, but do you believe in me? If you believe me, my cousin has a property with a market value of 600,000 yuan, but now the property is not very prosperous. If you are eager to sell it, it will be 500,000 yuan. I can lend my cousin 500,000 yuan, but he must transfer the property to me. When he returns the money to me, I will transfer the property back to him. Even if the price of the house has increased, and I don't want any more money. Even if the ownership is transferred to me, I don't need rent. If he doesn't pay back in 5 years, then I'll sell this house! I asked my aunt to go back and discuss with my cousin. My aunt cried and said, 'If the house is gone, what will he do in the future?'? This won't work. Even if your cousin doesn't pay you back, I will definitely pay you back if I smash the pot and sell iron! I said to my aunt: I understand, you are preparing to smash my pot and sell my iron! Do you think my money was brought by the wind? If you don't agree to this plan, then we don't have to talk about it! This is also a unique feature of China, where one likes to borrow money from others and vows to repay by smashing pots and selling iron, but there is no guarantee. Many times, doing business and living are the same feeling. Without effort or trust, how to close a hydraulic Sequence Valve deal? The payment of customers is also the same. Customers who pay attention to quality often make payments easily, which is what they say and do.

The reputation of AAK Hydraulic Valves is my life to me

What is the value of hydraulic valve manufacturers? How should I view the business of my company?   The starting point of all businesses is to benefit users. To benefit users is to provide "value" and "benefits" to users. When our R & D department wants to develop a new hydraulic valve, I ask them to know what function is very important, but also to figure out what users want, and creatively meet their needs.   The core responsibility of the operator of the hydraulic valve manufacturer is to seek the potential. Potential energy is to find the enhanced circuit of enterprises and businesses and make the flywheel rotate. How do I find the enhancement circuit of AAK Hydraulic Valves?   As an operator of hydraulic valve manufacturers, the most important core for me is reputation. But what is driving the improvement of "reputation"? Daily articles about the difficult and miscellaneous problems of hydraulic valves, such as how to help customers solve the problems that peers can't solve. So, what is driving the emergence of articles? Professional skills, on paper, will only be laughed at. It must sink into research and development, innovation, production, materials, equipment, technology, to analyze specific situations and solve specific problems, so as to be professional. However, what is promoting the accumulation of "professional skills"? Reputation. Only with an excellent reputation, can there be many high-quality hydraulic valve customers, allowing you to accompany, so that you can gain a lot of knowledge and practice. Did you find it? "Reputation - (+) > professional skills - (+) > Article - (+) > reputation", an enhancement loop, surfaced.   When I draw my flywheel, I am a very clear standard in my heart. I decided not to do anything other than pushing the flywheel. As long as it's not pushing the flywheel, don't do it. Once, an old customer introduced me to an Indian customer who can purchase 1,800 hydraulic valves every month. I was very moved, but I declined this Indian customer. Because the hydraulic valves he needs to purchase are very common market goods, and most hydraulic valve manufacturers can do it well. Helping him solve the supply of hydraulic valves may not help me improve my reputation. In terms of customers, we are the supplier of HydraForce for 9 consecutive years, which has improved my reputation. This is on my flywheel.   The essence of business is transaction, and in the transaction, you can only exchange something with the value you provide. For example, if you offer something worth 100 yuan, theoretically you can only get back 100 yuan. If you occasionally get more money than the value you offer, it will be taken away one day. Any transaction is not just completed one time.   Hydraulic valve trading is also to exchange commodities for money. The manufacturer takes the hydraulic valve, the customer takes the money, and we will exchange it. However, I think there is a more advanced transaction before this transaction. This transaction is not to exchange goods for money, but to exchange content for time. For example, I wrote an article on hydraulic valves, and then you spent some time here because you were attracted by the content of AAK Hydraulic Valves. The transaction of exchanging goods for money actually takes place in time. For example, you take time to watch my short video, in which I introduced a hydraulic valve, and then you came to inquire.   The first transaction is actually the soil of the second transaction. Only when it occupies the customer's mind or time first, it is possible to trade goods with him. However, the vast majority of hydraulic valve manufacturers only pay attention to the second transaction and look everywhere for the transaction of commodity for money. AAK Hydraulic Valves constantly release content, so that more customer cases can help those customers who have suffered losses in purchasing hydraulic valves, so as to consolidate the trust of AAK.   AAK Hydraulic Valves, only for reputation. https://www.aakindustry.com/inf , o-detail/hydraulic-valve-manufacturers-aak297
