Stephen is from a hydraulic equipment manufacturing company in Greece, and his 3-year procurement is very successful. At the beginning of the year, their customer customized the company's large tonnage cranes, with very high requirements for hydraulic cartridge directional control valves. Stephen chose a local hydraulic cartridge valve manufacturer who has cooperated with him for 3 years to make samples. During the prototype debugging, the connecting pipeline of the oil cylinder burst, causing the boom to drop abnormally. Their engineers advised that the key is to optimize the load balance of the hydraulic cartridge directional control valve. The manufacturer said that this hydraulic cartridge directional control valve benchmarks a standard part of HydraForce and cannot be improved. Stephen contacted more than 10 hydraulic cartridge valve manufacturers, but none of them was willing to improve the standard parts of HydraForce. Stephen was very worried. Stephen found AAK while browsing Google. He noticed that AAK was continuously supplying HydraForce and left a message: Can AAK optimize the hydraulic cartridge directional control valve of HydraForce standard parts? I guess that he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the story above. According to his hydraulic schematic diagram, production drawings of hydraulic cartridge directional control valve, and equipment work videos, AAK engineer said that the original system was designed as a double cylinder luffing structure. During the luffing operation, the cylinder motion was not synchronous. When the system was suddenly loaded, the double cylinders were biased and the pipeline burst. Only by optimizing the structure of the hydraulic cartridge directional control valve can the load balance of the system be improved. Stephen saw the hope and paid the development cost on the second day. After 35 days, AAK sent 12 samples of hydraulic cartridge directional control valves. 2 weeks later, Stephen informed by email that after replacing with AAK hydraulic cartridge direction control valves, the prototype debugging was smooth, no pipeline burst, and the equipment had been delivered to the customer. After the customer tried, there would be an official order. AAK optimized the structure of the hydraulic cartridge directional control valve, and set small tricks on the first and second oil ports of the valve body. The oil passage between the first oil port and the valve chamber is equipped with a detachable damper, and the inner wall of the valve chamber at one side of the second oil port is provided with a boss extending radially. After this optimization, the oil pressure connected to the first oil port and the second oil port of the valve can act on both ends of the valve spool respectively, and the valve spool can slide between the first working position and the second working position under the action of the pressure oil. When the valve spool is in the first working position, the first oil port of the valve body is connected to the second oil port, and when the valve spool is in the second working position, the oil path between the first oil port and the second oil port of the valve body is not connected. AAK hydraulic cartridge directional control valve, no longer need to worry about safety, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-directional- control-va , lves-aak413

Balram is from a hydraulic equipment manufacturing company in Chile. The purchase of 3 years has been smooth, but the recently purchased hydraulic cartridge pressure control valve has upset him. The hydraulic cylinder supplied by them was complained by a customer, the hydraulic shock caused serious vibration of the pipe, which was easy to crack and leak oil. It is judged by the after-sales that it was caused by the impact load of the hydraulic cartridge pressure control valve used to control the pipeline pressure of the oil cylinder. The impact load of the hydraulic cartridge pressure control valve must be reduced. The hydraulic cartridge pressure control valve manufacturer advised that the impact load cannot be avoided. Balram checked with different hydraulic cartridge valve manufacturers in China to solve the impact load of the hydraulic cartridge pressure control valve. A week later, it was still fruitless. Balram browsed AAK website on Google and clicked the articles or products about hydraulic cartridge pressure control valves for many times. He left us a message: How to reduce the impact load of hydraulic cartridge pressure control valve? My reply: There are many reasons for the problem, which should be analyzed in detail. According to the video of abnormal equipment sent by Balram, as well as the production drawings of hydraulic cartridge pressure control valves, AAK engineers judged that the structure should be optimized and AAK is 90% confident to be successful. Balram saw the hope and asked AAK to make samples. After 35 days, AAK sent 12 samples of hydraulic cartridge pressure control valves. Last week, Balram said that it had been 9 months since AAK hydraulic cartridge pressure control valve was used on the hydraulic cylinder, and the pipeline was free of vibration and cracking. The customer was very satisfied with this after-sales service. His boss has decided to replace all the hydraulic cartridge pressure control valves on this batch of hydraulic cylinders with AAK ones, so AAK can prepare materials in advance. According to the schematic diagram provided by Balram, AAK optimized the original structure of the hydraulic cartridge pressure control valve. It can realize small opening throttle back pressure, and meet large opening oil return to reduce pressure impact. It can effectively reduce the peak value of pulsating pressure impact generated by high-frequency commutation, avoid pipeline vibration impact damage, and reduce the impact load on the connection between the vibration table and the hydraulic cylinder. AAK made below 3 changes: 1. A cavity with a stop is formed between the upper part and the lower part of the valve body, and the upper end of the valve spool in the cavity is against the positioning nut. 2. A sliding block is arranged in the middle of the valve spool, a stop is arranged at the lower part, a pressure regulating spring is arranged below the stop, and the pressure regulating spring is fixed on the spring seat. 3. The spring seat is pressed on the plug, with an adjusting bolt in the middle. One side of the lower part of the valve body is provided with a radial oil inlet hole and an axial control hole connected with it. The other side is provided with a radial oil return hole, a damping hole and an axial oil return hole connected with both holes. The axial control hole is connected with the upper oil hole on the shoulder of the upper valve body. AAK hydraulic cartridge pressure control valve, no impact load, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-pressure-control- valves- , aak412

Giacomo is the purchasing manager of a German hydraulic equipment company. Last year, the hydraulic lifting platform designed by his company was very creative and needed to purchase a hydraulic pilot operated relief valve. It was originally planned to be promoted on the exhibition at the beginning of the year, but the test run was not smooth. There was vibration and loud noise during the lifting process. The problem was the hydraulic relief valve. Giacomo was confused because the valve came from an old hydraulic relief valve manufacturer who had cooperated for 5 years. According to the manufacturer, this hydraulic relief valve sample was completely made based on the drawing, and the accuracy, flow, pressure and other requirements fully comply with the original design. The engineer realized that there might be a problem in the design, and asked Giacomo to contact several hydraulic relief valve manufacturers, hoping to get some constructive suggestions. It has been a month, but no progress has been made. Giacomo suddenly remembered that during the last communication with Gerrit of Caterpillar, Gerrit mentioned that AAK Hydraulic Valve has great design ability. With Gerrit's introduction, Giacomo told me about their current difficulties, and also sent the original drawing of the hydraulic relief valve and the video of the test run. After repeated comparison and several internal discussions, AAK technical team basically determined the cause of vibration of the hydraulic relief valve and the preliminary solution. I told Giacomo that we are 90% sure, but AAK needs to redesign the hydraulic relief valve, which will take 6-8 weeks. Giacomo paid $2,000 for the development the next day. Six weeks later, AAK sent the newly designed hydraulic relief valve samples. A week later, Giacomo sent a video of the machine testing. The vibration and noise were gone, and the whole machine could rise and fall freely. Their engineers disassembled AAK hydraulic relief valve, only then did they know that AAK design was brilliant and had a sigh of "so it is". AAK adds parts to the resonant cavity of the hydraulic pilot operated relief valve, which reduces the volume of the resonant cavity and increases the stiffness of the oil under negative pressure. According to the principle that the components with high stiffness are not easy to resonate, we have adjusted the internal design of the hydraulic relief valve, added a vibration damping sleeve and a vibration damping pad to the pilot valve, and set various damping holes on the vibration damping sleeve to increase damping to eliminate vibration. The vibration damping pad can cooperate with the resonant cavity and move freely. There is a throttling groove on the front and back of the vibration damping pad, and the oil can also produce damping effect when flowing to change the original flow. Giacomo privately informed that after the successful test run, the whole team was very happy and their engineers admired him more and more. AAK hydraulic pilot operated relief valve, no vibration, no noise, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak261

Our hydraulic valve customer Pablo from the Netherlands has an order for hydraulic relief valves. Although the order qty is only 800, it requires very high precision of grooves. He asked me for a quotation at the first time, but he thought that the quotation of AAK hydraulic relief valve was 20% higher. I also agreed with him to check with the price other hydraulic relief valve manufacturers. Pablo consulted all the hydraulic valve suppliers on hand, and most of them said that they could not achieve the groove accuracy of the hydraulic relief valve drawing. Only 2 factories could have a try, but the price was at least 60% higher than that of the conventional hydraulic relief valves. Moreover, only after the sample was made, they could know whether the groove accuracy could meet the standard. Pablo was a little confused. After wasting a week, he returned to AAK Hydraulic Valve. Pablo was surprised that most manufacturers could not do the groove precision of hydraulic relief valve, which seemed to be a very conventional process. I told him that the cutting and processing area of this hydraulic relief valve was closed, with high resistance of the cutting tools, fast wear and tear, and difficult chip removal. The groove precision was even more difficult to ensure, that is, the conventional processing technology was not feasible, which was also the reason why so many hydraulic relief valve manufacturers gave up. At the same time, I told him that the two hydraulic relief valve manufacturers who were willing to try were 60% more expensive because they used high-speed milling to avoid tool damage and improve groove accuracy. This technology is not only costly, but also has very strict requirements for the entire processing system. Otherwise, the accuracy cannot be guaranteed, and most manufacturers cannot control this technology. Pablo was surprised by our understanding of the industry. It seems that he can only choose AAK to make the samples. Two weeks later, we successfully sent 6 samples of hydraulic relief valve. Their engineers approved AAK hydraulic relief valve samples at one time after receiving them. I fed back to Pablo that AAK adopted UG CAD module to solve this processing problem. No hydraulic relief valve manufacturer in Ningbo would think of using this technology. This technical point is imported from Germany. The CAD module of UG is used to model the geometric parameters of the groove, and then the CAM module of UG is used to NC program the machining of the groove of the hydraulic relief valve. The tool path and cutting method are set by programming. The NC program thus obtained can carry out the precise machining of the groove and solve the problem of chip removal. The reason why AAK can effectively deal with the high- precision machining of hydraulic relief valve groove is that after generating the tool path of machined parts, the whole process is simulated by using the simulation function of UG software. Our technicians can clearly see the processing path of the processing tool, that is, turn the closed area into a visible area. After the simulation, determine the tool direction through UG software, and then import it into the file of the NC machine tool to generate the code for executing the command. AAK hydraulic relief valve groove processing adopts simulation modeling technology, which not only reduces the cost, but also ensures the accuracy. You are welcome to try the order. https://www.aakindustry.com/info-det , ail/hydraulic-relief-valves-aak260

The bosses of China's manufacturing industry, as well as the hydraulic cartridge valve industry, all enjoy listening to "Dao". The source of China's "Dao" is the famous Chinese work "Tao Te Ching" 2500 years ago. The first sentence at the beginning of the book is: ' Dao that can be daoed is not the true Dao'. It is said that any truth that can be expressed is not an eternal truth, and there are times when it does not hold true. Dao, in fact, is not concrete and can only be understood by meaning, but cannot be conveyed in words; So what is this Dao? I really don't know. The big and small leader in the hydraulic cartridge valve industry, focus on 3 tasks every day: reading books, reading things, and reading people, to improve oneself through these 3 dimensions or solve problems encountered in the hydraulic cartridge valve industry. The Tao that I have come to realize also comes from 3 aspects. 1. There is only one Dao to manufacture hydraulic cartridge valves, that is the manufacturing quality of hydraulic cartridge valves. 2. There is only one Dao to promote hydraulic cartridge valves, focusing on density and thickness in network promotion. 3. There is only one Dao to sell hydraulic cartridge valves, which is to maintain the integrity of the enterprise and win trust. Regardless of the type of manufacturing industry, there is only one Dao, which is manufacturing quality. Only with the quality of domestic first line brands or benchmark the quality of global first line brands, you can remain invincible in this industry. The manufacturing quality of AAK hydraulic cartridge valves is benchmarking against SUN Hydraulics and HydraForce. Domestic small and medium-sized factories or manufacturing industries are upgrading, and low-end manufacturing will inevitably shift to Southeast Asia and Central Asia. In the future, if there are no orders and it is difficult to find jobs every day, it indicates that the industry has not upgraded and still wants to live on low-end orders. Upgrading the industrial goal and positioning it in the manufacturing quality of global first line brands. There is only one Dao to promote hydraulic cartridge valves, focusing on density and thickness in network promotion. The way to make money in the manufacturing industry is to sell goods online, and of course, it can also rely on salespeople to enter the market, establish relationships, give kickbacks, and other means to sell out. If a factory owner still has to use fancy relationships, will he have time to focus on manufacturing quality, and energy to upgrade products? There is only one Dao for the sales of hydraulic cartridge valves, which is the integrity of the enterprise and the trust of customers. In what state will a trustworthy businessman go awry? If you lack money, you will definitely easily get into trouble. Or rather, when a person is short of money, it is difficult to maintain integrity, even though he has always been very trustworthy. Online merchants, in a virtual world, do real business. Due to being separated from the internet and invisible to both buyers and sellers, there is a great need for honesty. Time and time again, honesty accumulates trust, which is the best golden signboard for online merchants, and it is even more powerful than brand. Dao relies on enlightenment, not just taking it. Chinese manufacturing bosses like to listen to "Dao" and just wonder if there are any available methods. As long as the methods, skills, and answers are given directly, whether it is from books, classrooms, or teachers, it is hard to be implemented. Many people always try to find solutions from others or the outside world, just like seeking a master key, so that they don't have to think or grow, and can solve all problems lying still. This is a typical example of finding shortcuts and being lazy. Laziness, the laziness of most people, is with the ability but not doing it. Knowing where the problem lies is simply procrastinating or not learning new methods. The most obvious thing is that hundreds of thousands of people are filming videos and doing live broadcasts, just you are not able to do it? Definitely not, it's laziness. I know that the video and live streaming effects are good, but I just don't do it. The order still comes from the old way. Why not do video and live streaming? AAK hydraulic cartridge valve, adhere to 3 Dao: the manufacturing quality of hydraulic cartridge valves, the density and thickness of network promotion, the integrity of the enterprise and win the trust.

Last night, a rich second generation from a hydraulic cartridge valve manufacturer invited me to dinner. He not only wasn't angry with someone who caused him embarrassment, but also said it was his own fault and taught me a lesson. Before telling this story, I thought of what I saw in Shanghai a few days ago. A hydraulic cartridge valve manufacturer get along well with me introduced a customer to AAK, and asked me to go to Shanghai for a face-to-face communication. In the top office buildings of the company in Shanghai, I saw most of the executives who were very friendly to security guards and cleaning aunts, actively waving and smiling. Suddenly, I felt that wealthy people are very approachable to the bottom class now, but it used to be different. The rich second generation of this hydraulic cartridge valve manufacturer is a friend of my classmate. He is gradually taking over his father's hydraulic cartridge valve factory. Their family not only operates hydraulic cartridge valve factory, but also engages in financial businesses. Anyway, they are very wealthy, even their family does nothing, and this generation is not worried about food or clothing. Last night while we were eating at the restaurant, a waitress accidentally knocked over a large glass of beer with her elbow, spilling all over his pants. My friend smiled and didn't get angry. He wiped it himself and said to the waitress, 'It's okay, you're busy with your work.'. I felt that the waitress was quite nervous. After a while, the waitress and the restaurant manager came together and apologized to him together. The manager also said that he would deduct the waitress's bonus. Upon hearing this, he directly said to the manager, 'Don't criticize her. I touched it myself, not the waitress. She was not wrong'. I suddenly felt that this guy has excellent character and extremely high quality, and the people at our table also praised him. As a result, he was also happy, but what he said next overturned the Three Views. He said, 'This is to protect myself, there's no need to argue with them. They don't have much money. If this makes them feel bad and puts their anger on me, I don't have to gamble with them. My time, my value, is more valuable than theirs.'. After thinking about it later, it was actually true. Many times, the approachability shown by those who are particularly advanced is rooted in the fear of causing unnecessary trouble. If this logic is extended to business, there is no need for hydraulic cartridge valve manufacturers to argue with some customers. We have new customers inquiring every day, and there is no need to spend more time on hydraulic cartridge valve customers who are haggling fiercely and demand more, as well as those who may not be able to afford hydraulic cartridge valves. Refusal in good faith also protects the hydraulic cartridge valve manufacturer AAK In fact. For major customers, especially those from the Fortune 500 or those who value quality, as long as your manufacturing quality is recognized by them and the delivery time is guaranteed, everything else is easy and they do not haggle over the price. Hydraulic cartridge valve manufacturer AAK enjoys serving these customers the most. While striving for manufacturing quality, we adhere to daily dissemination of our customer cases, production processes, and process technical skills. Churchill said to his compatriots, "I have nothing, all I can offer is blood, hard work, sweat, and tears." And I want to say to customers or potential customers of hydraulic cartridge valve manufacturer AAK, "After reading and writing for so long, I still know nothing. All I can offer is sincerity Customer first, no one pays attention to you; Customer obsession, love you for 3 years. Hydraulic cartridge valve manufacturer AAK is only willing to do things that fascinate customers.

Ernst is from a German hydraulic equipment company. He has been doing well in recent years, and his boss is optimistic about him. The hydraulic relief valves purchased this time has suffered a big setback. In the second half of last year, the hydraulic power unit sold by their company for less than 3 months was complained by customers. When the pressure of the hydraulic relief valve was adjusted to 450bar, the equipment idled. The engineer thought that it could be solved by changing the motor. As a result, after the equipment started for a while, the same situation happened again. The engineer checked each component, and it turned out that the spool of the hydraulic relief valve was stuck. After the boss knew about it, he asked Ernst to request the original hydraulic relief valve manufacturer to solve the problem and bear the motor cost twice. Per the manufacturer, the price of the hydraulic relief valve is too low this time. Under the high pressure of 450bar, it is difficult to avoid a few stuck occasionally, then there is no further news. Ernst had no choice but to find new hydraulic relief valve suppliers. Ernst contacted more than 10 factories and requested that the hydraulic relief valve be 100% free of jamming within 1 year under the high pressure of 450bar. Only two factories were willing to cooperate with the samples, and other manufacturers gave up directly. Ernst still seemed worried about wasting time. With the introduction of his friend Steven, who is our old customer, he contacted AAK hydraulic valve. Ernst asked us to make samples directly according to his hydraulic relief valve drawings and working conditions. The key of this hydraulic relief valve is how long the service life of the hydraulic relief valve is under 450bar high pressure? Actually, AAK has already mass produced hydraulic valves with similar requirements. Nine months later, Ernst informed by e-mail that the hydraulic relief valve from one factory had been on strike because of its stuck, and the other factory's, although still working, it was estimated to be less than 12 months. After 9 months of use, the parameters of AAK hydraulic relief valves are still stable and function normally. Ernst said that compared with more than 10 factories, AAK high-pressure hydraulic relief valve has the most stable performance and longest service life among all the manufacturers he knows. Ernst estimated that he would not need to change the hydraulic relief valve suppliers any more. AAK hydraulic relief valve has 3 advantages and has already surpassed its domestic counterparts.   1. AAK has a high-precision CNC machining center imported from Switzerland and its own upgraded and refitted independent fixture, which eliminates human errors. The high-precision control of component processing is the key point to prevent jamming. 2. AAK has engineer team with over 10 years of technical experience, independent professional research and development, with unique research and development technology, select the raw materials and spare parts according to the working conditions of customers' actual needs. The selection of materials is the key to determine the service life of the hydraulic relief valves. 3. Through EasyForm software, AAK can accurately and quickly measure each valve component to ensure that the concentricity of each hydraulic relief valve is 100% consistent and prevent jamming. Detection is the final check on the quality control of the hydraulic relief valves. AAK hydraulic relief valve is resistant to high pressure and has no jamming.

Each of us is exchanging value with the world. Whether you are an individual, manufacturing industry or other roles, you can't do without "exchange". The essence of business is exchange, such as AAK Hydraulic Manifold, which is exchanged with the value of our hydraulic manifolds to the customer's US dollar price. However, the time dimension of this value exchange determines the level and pattern of the enterprise. The exchange of some hydraulic manifold manufacturers is based on the "present", which is the first level in my understanding. These hydraulic manifold manufacturers do onetime deal. Pay the money and deliver the goods at the same time, then call it quits. This way is fast, simple and direct, but not a long-term one. The exchange of some hydraulic manifold manufacturers is based on "a lifetime", which is the second level in my understanding. These hydraulic manifold manufacturers should not only do business with customers once, but also do business with customers all the time. If you have such a perception in your mind for a lifetime, then people will become broader and more honest. Because honesty means that we have to play repeated games with the world. Exchange honesty for trust. Exchange integrity for benefits. This is a simple business cognition, but it is also a personal awakening. Most of the people who make you feel comfortable have reached this level, whether they are owners of small hydraulic manifold manufacturers or large entrepreneurs with tens of billions of scale. They will adhere to long-term principles throughout their lives. The exchange of some hydraulic manifold manufacturers is based on "generation after generation". This is the third level in my understanding. What is more long-term than life is life after life. Enterprises have a longer life than entrepreneurs. Brand life is longer than product life. Therefore, all values and trust are accumulated in the enterprise and brand. In this way, there will be a century-old enterprise and an everlasting foundation. People who want to do business with the world from generation to generation, you will find that they are more selfless, fearless and more socially responsible. AAK Hydraulic Manifold, is unwilling to keep pace with its peers on the first level, has stood on the shoulders of the second level, and may be on the way to the third level. I don't have to be the winner. As long as it is valuable, I will do it. It doesn't matter whether I succeed in my lifetime or after a hundred years. This is really the mind worthy of our respect, the object of my study, and the step I have been pursuing. After hearing the truth and rules, masters will really practice day after day. Most people are half convinced when they hear the truth and rules. The outmoded people laughed when they heard this. So, what should we do? Become a master. Practice, try, act and summarize. Only in this way can the external truth be internalized into one's own ability. Only external laws can be internalized into their own cognition. That's it.
