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. The greatest truths is concise, and heavy swords don’t need edgy blade. AAK Hydraulic Manifold is only willing to be a master, and is different from most hydraulic manifold manufacturers. In the business world, it is difficult to go further. But as we often say, hard roads are never crowded. AAK Hydraulic Manifold, no matter how far it is, insists on taking steps every day, and will eventually arrive. https://www.aakindustry.com/info-de , tail/hydraulic-manifolds-aak481

Oliver comes from a hydraulic equipment company in Canada. At the end of last year, they planned to develop a hydraulic cylinder that uses a hydraulic directional control valve. The parameter requirements are high, especially the internal leakage should be less than 2drops/min. Oliver inquired about more than 10 manufacturers of hydraulic directional control valves. Only one supplier who had cooperated for 5 years told him that he was 90% sure. Other manufacturers surrendered. One month later, the hydraulic directional control valve was installed with the oil cylinder. Less than 12 hours after startup, the hydraulic oil cylinder was unstable during reciprocating motion. After disassembly, the engineer found that the hydraulic directional control valve had internal leakage exceeding the requirement of 2 drops/min. Oliver was very helpless. He continued to look for new manufacturers of hydraulic directional control valves, and they all basically replied that they could not meet the requirement of internal leakage. Oliver found an article on Google, "The internal leakage index is equaled to the local manufacturer in Germany, but AAK hydraulic threaded cartridge valve has better cost performance”, and left a message on our website: can you customize the hydraulic directional control valve with internal leakage of 2drops/min? At first glance, I knew that this was an accurate customer consultation. Although the internal leakage of 2drops/min was difficult, AAK had mass production 1 year ago. We suggested him send us the drawings and working condition requirements of the hydraulic directional control valve, and AAK can make samples directly. If the internal leakage of the hydraulic directional control valve does not meet the standard, 100% of the development cost will be returned. According to the development data provided by Oliver, there may not be any other manufacturer that can provide guarantee except AAK. After 30 days, AAK successfully sent 8 hydraulic directional control valve samples. Three months later, Oliver informed that no abnormality of the hydraulic directional control valve was found during the 3 internal commissioning of his company. After the hydraulic cylinder was tried out by the user, the feedback was also very good. Oliver is curious about the hydraulic directional control valves surrendered by so many manufacturers. Why did AAK samples succeed at one time? AAK hydraulic directional control valve has 3 absolute advantages and has already surpassed its domestic counterparts: 1. The precision honing machine imported from the United States is used to finish the valve hole and valve spool of the hydraulic direction control valves for more than 3 times. The dimensional accuracy of the valve hole is IT7 ~ 4, and the surface roughness can reach Ra 0.32 ~ 0.04μm, thus meeting the requirements of high accuracy. 2. AAK engineer team, select the raw materials and spare parts based on the requirements of working conditions, and never follow the ordinary market. Especially in the customization of high requirement hydraulic directional control valves, they have rich experiences and cases. 3. AAK has been OEM factory of hydraulic valves for 3 of the world's top 500 companies for 10 years. The quality control process is more strictly self- executed than the ISO certification system. It sticks to manufacturing details, focuses on process innovation, and focuses on technology research and development. Ensure that each hydraulic directional control valve has anti fatigue, high precision and long service life. AAK hydraulic directional control valve, 2drops/min internal leakage, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valves- aak258

Mike is a Canadian customer who has cooperated with AAK for more than 2 years, and he has been very smooth in purchasing hydraulic valves. But in May this year, he suffered a lot in purchasing this hydraulic pressure valve. The order for a hydraulic pressure valve originally supplied by an American manufacturer, was not accepted by the manufacturer due to capacity. He contacted some Chinese hydraulic pressure valve manufacturers. To his surprise, most manufacturers offered 20% more than the original American manufacturer, and two of them were about the same price as the American manufacturer, however, the surface roughness and diameter tolerance of the hydraulic pressure valve samples were not up to standard. Mike was distressed that he couldn't find a substitute for the original American hydraulic pressure valve manufacturer. Mike knows that AAK HYDRAULIC VALVE is a manufacturer that pays attention to quality, and its price will be higher than that of its domestic counterparts. With regard to this hydraulic pressure valve, he emailed me and asked why most manufacturers offered 20% more than the original American manufacturer? For this abnormal situation, I told him directly that it must be due to the high defective rate of processing. AAK is confident that the price is cheaper than American manufacturer, and the quality is not inferior to American manufacturer. According to the drawings of the hydraulic pressure valve issued by him, AAK technical team found that the processing was really exquisite. It requires that the coaxiality and roundness of the Φ8mm/Φ9mm hole should be less than 5μm, and the Φ15mm/Φ9mm orifice should be free of burrs. To guarantee coaxiality and roundness requirements of 5μm, and keep the inner wall of the hole at 0.6μm roughness, at least 50% of valves should be scrapped according to the existing processing technology. This confirms my guess that why the quotation of domestic manufacturers is 20% higher than that of American original manufacturer. Mike was not calm after receiving the quotation of AAK hydraulic pressure valve. He repeatedly confirmed with me whether the price was wrong? The price of AAK is not only cheaper than that of domestic manufacturers, but also 30% cheaper than that of American manufacturer. I told him that this hydraulic pressure valve can only be drilled and reamed for many times by domestic peers, which not only has a long processing cycle, but also is difficult to ensure the processing accuracy. At the same time, the whole hole processing including tool change time is at least 210 seconds, and most of the tool life is less than 500 holes, which is time-consuming, money consuming, and what is worse, the qualified products are very limited. Of course, the cost is high. Mike asked me to try the sample directly. 2 weeks later, we sent the hydraulic pressure valve sample. 5 days later, Mike’s team confirmed the quality of AAK hydraulic pressure valve at one time, and the production time provided by AAK was less than half of domestic peers. For processing this hydraulic pressure valve, we use integral cemented carbide tools, and use 3 efficient tools to replace the original 9 tools. We also use special guide strips and internal cooling design to maintain tool life and improve cutting speed and machining accuracy. The number of inner holes can be stabilized at 3000, which is 6 times that of peers. The internal leakage of the whole machine has also been reduced from 1.6 to 1.1, and the processing and tool change time has been reduced to 45s, which is only 22% of peers. Such efficient and high-quality processing is not our temporary idea, but the result of adhering to technological innovation. There may not be such a second hydraulic pressure valve manufacturer in Ningbo. AAK hydraulic pressure valve is benchmarked to the quality of American manufacturer. You are welcome to test an order. https://www.aakindustry.com/info-det , ail/hydraulic-pressure-valve-aak256

Timon is from a hydraulic equipment manufacturing company in the Netherlands. He has been smooth on purchasing hydraulic cartridge valves from China. A hydraulic cartridge proportional control valve he purchased in the second half of last year was in trouble. For a customer, they customized a hydraulic forging presses, which require high speed when unloaded and low speed when overloaded. The key to the stability of the hydraulic system and the stepless speed control of the equipment is the hydraulic cartridge proportional control valve. Timon worked with a manufacturer of hydraulic cartridge proportional control valves who has cooperated with them for 3 years to try samples. During equipment commissioning, the main working cylinder had abnormal pressure relief, which would seriously affect the service life of the equipment. After several rounds of inspection, the problem was locked in the structure of the hydraulic cartridge proportional control valve, but the original manufacturer was unable to optimize it. Timon contacted more than 10 hydraulic cartridge valve manufacturers. A week passed, but there was no solution. Their engineer has push for progress 3 times. Timon found AAK Hydraulic Valve on Google, stayed on our website for 11 minutes, and left a message: 1. Can AAK optimize the structure of a hydraulic cartridge proportional control valve? 2. Can the optimized hydraulic cartridge proportional control valve improve the large pressure impact of the hydraulic system? 3. What is the lead time and development cost for customizing the hydraulic cartridge proportional control valve? After communication, we learned about Timon's procurement dilemma. After checking the system schematic diagram and original design drawings of his hydraulic cartridge proportional control valve, AAK engineers understood the direction of optimization. When Timon learned that AAK was 90% sure to be successful, he asked us to make samples. After 30 days, AAK sent 10 samples of hydraulic cartridge proportional control valves. 3 weeks later, Timon said that the equipment had been delivered to the customer, and their engineers were very satisfied with AAK hydraulic cartridge proportional control valve, which completely solved the problem of large pressure impact in the hydraulic system of the forging press. AAK hydraulic cartridge proportional control valve can accurately control small flow and large flow, with small flow fluctuation and small pressure impact. The key is that AAK hydraulic cartridge proportional control valve has the function of variable flow gain. The structure is that the lower part of the hollow valve spool is put into the valve cage and sealed with the valve cage line. The upper part of the hollow valve spool is matched with the control cover plate. The upper end of the control cover plate is connected with the valve cover, and the valve cover is equipped with a displacement sensor. A pilot control valve is installed on the side of the control cover plate. The port at the bottom of the valve spool is processed with a semicircular hole, and the valve cage is provided with 4 symmetrical waist holes. With the optimized structure, when the opening of the hydraulic cartridge proportional control valve is small, the flow gain is small, and high-precision linear control of small flow can be realized. When the opening amount is large, the flow gain is large, and high- precision linear control of large flow can be realized. Under the high- precision linear control of large flow, the hydraulic cartridge proportional control valve has small flow fluctuation, small pressure impact, and the service life of the valve is increased by at least 30%. AAK hydraulic cartridge proportional control valve, variable flow gain function, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-proportional- control-val , ves-aak411

Chadwick is from Israel and has just purchased hydraulic cartridge valves from manufacturers in China for no more than half a year, but encountered problems when purchasing a hydraulic cartridge pressure control valves. One of their hydraulic manifolds needs a hydraulic cartridge pressure control valve with 2μm accuracy spool. Chadwick knew that the accuracy was high, so he chose a hydraulic cartridge valve manufacturer in Ningbo from the current supplier list. Perhaps the working conditions have high requirements. The original manufacturer has tested 3 times, and each time several hydraulic cartridge pressure control valves leaked. The original manufacturer can only give up because the valve spool accuracy of this hydraulic cartridge pressure control valve is not easy to control. Time has been wasted for almost 3 months, Chadwick was very anxious. I'm not sure how Chadwick found AAK. The message he left us was only a picture of the valve spool, with a question if AAK is able to meet 2μm accuracy? For questions like this, whether the answer is yes or no, it is not persuasive. I only told him that AAK provided hydraulic cartridge valves with 1μm accuracy spool for Russian customers previously, and did not say too much. The next day, Chadwick sent detailed drawings of the hydraulic cartridge pressure control valve. After communication, it was learned that he had wasted 3 months with the original manufacturer. I told him that AAK only make samples one time, either get it done or give it up because this valve spool is really a bit special. After 40 days, AAK sent out 30 hydraulic cartridge pressure control valves. 1 month later, Chadwick sent us an order for 200 pcs of hydraulic cartridge pressure valves, which means that AAK hydraulic cartridge pressure control valve has been recognized. I told him that the main focus is not only on the precision machining of the valve spool, but subsequent testing is also crucial. Perhaps most hydraulic pressure control cartridge valve manufacturers in China only focus on precision machining but ignore the details of testing. AAK hydraulic pressure cartridge valve spool has no abnormalities, because it is only after each valve spool has been tested, the next process can be proceeded. The detection of this hydraulic cartridge pressure control valve spool adopts a Japanese KEYENCE optical axis measuring instrument, which is fully automatic and 360 degree detection. The dimensions, contour, accuracy, and surface roughness of the valve spool do not require manual inspection. Each process is displayed on the computer screen synchronously. If there is a deviation, a red reminder will automatically appear on the screen. The detection of AAK not only avoids human error, but also improves the detection speed by more than 10 times, not only fast, but also very accurate. AAK hydraulic cartridge pressure control valve, from processing to testing, is unique, you can give it a try!

Most hydraulic manifold manufacturers in Ningbo China only produce manifold blocks and do not produce hydraulic cartridge valves. The production of manifold blocks is relatively simple compared to hydraulic cartridge valves. A while ago, Tomi from Italy found hydraulic manifold manufacturer AAK and hoped that we could develop a manifold block. Tomi initially hoped that the original hydraulic manifold manufacturer would develop a whole set of manifold assembly, but the manufacturer delayed time by selecting hydraulic cartridge valves. Tomi had to take remedial measures and only purchased manifold blocks from the original hydraulic manifold manufacturer, but now they have been put on hold due to the complex oil circuit and inadequate processing of the manifold blocks. Tomi realized that finding a reliable hydraulic manifold manufacturer is too important. According to the manifold block drawing sent by Tomi, the oil circuit holes are complex and the accuracy is also high. I told Tomi that hydraulic manifold manufacturer AAK can deliver the manifold blocks within 40 days. Last week, Tomi asked about the production progress of the manifold block. I estimated that due to the bad experience with the original hydraulic manifold manufacturer, he was also worried that the hydraulic manifold manufacturer AAK would delay his progress. I went to the workshop to take a video of the manifold block being processed for him, so that he could feel at ease. We have chosen Hision Precision Horizontal Machining Center for this manifold block, which adopts a three-axis three-dimensional positioning system and is equipped with a high-speed electric spindle. It is also equipped with spindle bearings and gearbox cooling devices, which not only improves lubrication efficiency but also avoids errors caused by thermal deformation of the spindle box, providing assurance for the accuracy of the valve hole. At the same time, the equipment adopts a hydraulic tool changing system, which can achieve fast and automatic tool changing and solve complex valve hole machining. The equipped CNC system can be intelligently controlled, ensuring the machining accuracy and progress of manifold blocks. 　　 Hydraulic manifold manufacturer AAK in China, equipment 3 advantages, 2 guarantees, you are welcome to try a small order!

Laird is from Brazil, and we met 2 years ago. He conducted 6 inquiries, 3 trial orders, and 1 trial order for hydraulic directional control valves with AAK. But there has been no inquiry in the past 6 months, which surprised me. I have checked with him twice but there has been no response. It wasn't until Laird contacted me a few days ago that I learned about the sealing story of the hydraulic directional control valve cover cap and valve cage. In the second half of last year, their hydraulic power unit required hydraulic directional control valves. Laird inquired from 3 hydraulic directional control valve manufacturers in China, and AAK also provided quote. Laird chose a hydraulic directional control valve manufacturer with competitive price. 6 months later, the customer complained about hydraulic directional control valve leakage, causing unstable system operation. On site, it was found that the leakage point was between the hydraulic directional control valve cover and valve cage. The original valve manufacturer claimed that it was caused by severe vibration and he could only guarantee the service life of the hydraulic directional control valve for 6 months. However, the customer requested at least 1 year or more. Laird thought of the hydraulic directional control valve previously supplied by AAK, which had no abnormal leakage and had a service life of over 1 year. I told him that last time, AAK hydraulic directional control valve was quoted 20% expensive than its peers, but its service life was twice that of its peers. This time, it has been verified again with you. Let's make a comparison. Our quotation for this hydraulic directional control valve is $12.00. Based on a 1 year calculation, the monthly usage cost is $1.00. If the original valve manufacturer's price is $10.00 and the service life is 6 months, then the monthly usage cost is over $1.50. This is the invisible benefit that AAK hydraulic directional valve brings to customers. Laird agreed with my explanation and sent an order for 200 pcs of hydraulic directional valves the next day. How to avoid vibration and leakage in the sealing between the AAK hydraulic directional valve cover and valve cage? This is a small detail, AAK has tricks. AAK uses thread anaerobic adhesive, which is evenly injected into the joint and self cured at room temperature. After curing, it will not be corroded by hydraulic oil or other organic media, and the key lies in the uniform injection method. This avoids loosening of threads caused by vibration between the hydraulic directional valve cover cap and valve cage, while protecting the joint from corrosion. The seal between the AAK hydraulic directional valve cap and valve cage is not loose or leaking. AAK hydraulic directional valve, no leakage, you can also give it a try!

I have some insistence that some of my counterparts in the hydraulic valve industry think that it is strange and even unnecessary. For many things, I am quite soft, but once those insistences are touched, I immediately become as hard as steel.   The price of hydraulic valves: as a hydraulic valve manufacturing company for more than 10 years, we have inquiries from new hydraulic valve customers every week, they are mostly B2B customers. These buyers are particularly concerned about one thing: price. This seems to be nonsense. Everyone cares about the price. What I am talking about is not the level of prices, but the consistency of prices.   Once, a hydraulic valve customer from Chile made an inquiry through e-mail. After several rounds of communication, he asked for my social account. I was a little puzzled. He asked privately: are you sure that the price you gave me is the same as others? I know that my Chilean counterparts also purchase hydraulic valves from AAK. I said of course. The same hydraulic valve, the same quantity range, and our price are always the same. He still seems worried. I know this is your principle, but have your colleagues really made no exceptions? I said no. I insist on that.   He said that last year, he purchased a batch of hydraulic valves from manufacturer A. The price was very expensive and the quality was good. It was a purchase order specially approved by his boss. A few days ago, his boss met one of his counterpart and learned that his counterpart also purchased the same batch of hydraulic valves from manufacturer A in the same quantity, but the price was much lower. The boss felt that he had been wronged. When he came back, he flew into a rage and asked me if I had taken a rebate. That was wrong. For AAK hydraulic valve, it would be great to have one more customer. However, if there is one more customer, it is at the cost of hurting another customer who once trusted you by using the "big data" method, this is too "expensive". I insist on not being manufacturer A. I said, I see. Trust me. The next day, his hydraulic valve PO came. The punctuality of AAK hydraulic valve: in my mind, there is no punctuality, either early or late. You choose by yourself. At first glance, it seems strange, right? But when I think about it, we often say the word "punctuality". What's the perspective? This is the other side's perspective. For example, when a meeting is held at 8 o'clock, the other party expresses the schedule. What about changing to your own perspective? What's on time? I have only two choices. Because this is important, because I respect this group of people, because I have to do something else. In short, a positive idea will choose to arrive early. In AAK hydraulic valve, only early, not late. AAK hydraulic valve, there are still many more strange insistence. For example, in the discussion on the development technology of hydraulic valves, we insist on not saying anything we don't agree with. For this reason, we have offended the customer's engineer and cancelled the order. For example, we insist on not giving rebates. Some buyers are willing to add a few more points to the PO, and then give them rebates. This makes it difficult for me to explain to his boss. These insistences, in my counterparts’ opinion, may be completely unnecessary or even totally wrong. But these are my insistence. Please don't touch, I insist. But what if one day, because of these insistences, the company goes bankrupt? Then go bankrupt. I have always believed that no matter in business or in communication with people, there are 3 most important elements: the first is honesty, the second is frankness, and the third is trust. Business method can decide how high to fly, and business ethics can decide how far to fly. You might say, what if you can't be yourself voluntarily? If there is no way to do the right thing, at least not to do the wrong thing; if there is no way to tell the whole truth, at least not to tell lies. The fundamental solution is to engage in the production of hydraulic valves, not to do evil, not to fabricate, not to be greedy, to do a good job in the manufacturing quality of hydraulic valves in a down-to-earth manner, and to give back to customers. When the company is faced with the difficult decision of performance and dream, what the company needs is a real crisis, so that all internal forces can feel the real crisis of death, the crisis of trembling performance, and the crisis of silence for all. Then the company can be reborn. For individuals, only by choosing integrity values can they go further and more steadily. AAK hydraulic valve can only take a road that few people take and do difficult and correct things. All the difficult things will become simpler, and the simple things will become more and more difficult. Because the difficult road is never crowded. Let's bless AAK hydraulic valve. https://www.aakindustry.com/info-det , ail/hydraulic-valves-aak255

Achilleas comes from a Greek hydraulic equipment company. One of their rollers was complained by users because of oil leakage. After sales personnel found that there was a large gap in the valve block used for hydraulic manifold, which was the root cause of oil leakage. After further disassembling the hydraulic manifold, it was found that there were cracks in the lower left and right corners of the valve block. They thought that the problem can be solved by replacing the valve block. However, after 2 months of construction, the old problem was happened again. The engineer asked Achilleas to consult the original hydraulic manifold manufacturer. The manufacturer was not sure why the valve block broke within 2 months. Achilleas was helpless. Achilleas realized that he could only contact AAK for help, because he also sent the inquiry for this hydraulic manifold to AAK before. At that time, AAK proposed to modify the oil circuit and hydraulic valve selection, but it was not accepted by their engineers. I was not surprised to receive his email. At the inquiry stage last year, our engineers found that there was an energy conflict between the oil circuit aperture of the hydraulic manifold and the selected hydraulic valve, resulting in the frequent instantaneous pressure rise of the hydraulic system. In particular, the oil circuit wall thickness at the left and right lower corners of the valve block is not enough, so it is not surprising that the valve block is cracked. This time, Achilleas didn't go to their engineers to verify. AAK redesigned the oil circuit, re selected each hydraulic valve, and sent the hydraulic manifold block sample after 30 days. Last week, Achilleas sent an email saying that after replacing with AAK sample for such a long time, there was really no problem. Moreover, the total price was saved by 20% compared with the original one, and the customer feedback that the action sensitivity was also improved a lot. This time, even their engineer also suggested that the boss should give the design and production of the hydraulic manifold block to AAK in the future. He also wants to know why AAK is so good? I told him that the most important thing in the design of the hydraulic manifold block is to determine the operating parameters of the hydraulic system, understand the requirements of the system for the maximum working pressure and maximum flow, and reasonably design the oil circuit. Secondly, the pressure drop of the valve must be considered to ensure that the pressure drop through the pressure valve, flow valve and directional valve is not too high, which will affect the load action and cause the pressure problem of the valve block. AAK has more than 20 years of industry experienced professional engineer from German HAWE company, who have unique experience in the design of hydraulic manifold blocks, especially in the oil circuit design. Combined with the system principle, through the reasonable selection of hydraulic valves and the innovative and optimized design of the oil circuit of the valve block, the oil leakage caused by high pressure can be avoided, and an efficient, economical and reliable hydraulic manifold block can be produced. Maybe there is no such second hydraulic manifold block manufacturer in Ningbo. AAK hydraulic manifold block is economical, efficient and reliable. You can also try it! https://www.aakindustry.com/info-detail , /hydraulic-manifold-aak254

A report said that the average life span of Chinese enterprises is less than 3 years, and the life span of large enterprises is rarely more than 35 years. One third of the world's top 500 enterprises have disappeared. AAK Hydraulic Manifold is 9 years old, and I have been in awe of his premature death, so I walk on thin ice every day, constantly cultivate myself and build team. Most failed enterprises have their own problems, but their basic problem may be poor learning ability. This is also what I learned from Peter Shengji's "The Fifth Cultivation" recently.   1. Cultivate the mental model of the founder of the enterprise. 1）Identify leaps of abstraction: pay attention to how your mind jumps from observation to general conclusion.   2）Practice the left-hand column: write down the words that your heart usually won't say.   3）Balancing inquiry and defense: the technique of openly discussing problems with each other;   4）Face up to the difference between what we say and what we do.   These 4 skills are not easy for me to grasp at present, but I have already put them into practice, and I believe they will be fruitful.   2. Use the mental model to influence the team and build a learning team.   Whether the above 4 skills are suitable for you or not, it is important for enterprises to find their own ways to change the mental model of managers and discuss problems openly. The learning of manufacturing enterprises may only be internal and external.   AAK Hydraulic Manifold, team's internal learning, analysis and face up to our shortcomings and strive to correct them. Many business owners are admonishing: do as I say, not as I do! In fact, the boss's behavior will imperceptibly affect everyone around him. AAK Hydraulic Manifold requires the front-line staff of the workshop to do it according to the process, operation SOP, and benchmarking data, and insist on manufacturing quality. The management personnel are required to guide and supervise according to the process.   The internal benchmark of AAK Hydraulic Manifold includes the front-line workers in the workshop, managers, technicians and R&D departments. As long as they have successful behaviors, they will become a model for AAK hydraulic manifold team to learn.   AAK hydraulic manifold, external learning: focus on top brands, starting from imitation. 9 years ago, when we decided to upgrade our products and do hydraulic manifolds, our only expertise was the production of hydraulic cartridge valves, no any experience about the design of hydraulic manifolds, the selection of cartridge valves, the production of manifold blocks, and the assembly and testing of hydraulic manifolds. We spent a lot of money to buy SUN's hydraulic manifolds to imitate, and summarized the underlying logic from the hydraulic principle. We hired engineer who have worked in HAWE for more than 10 years. Take small steps and accumulate every day, until to serve 3 major types of customers, such as Honeywell the Fortune 500 company, Skyjack the listed company in Canada, and BL the military industry company in Israel.   The external benchmark of AAK hydraulic manifolds includes the hydraulic manifold manufacturers from the first-line brands, the Honeywell from the world's top 500, the customers of listed companies. These customers with the characteristics of exquisite requirements, urge AAK Hydraulic Manifold employees to keep learning, growing and making progress.   AAK Hydraulic Manifold, team learning, from inside to outside. An excellent team needs not only talented individuals, but also the atmosphere of learning. An atmosphere of mutual learning is formed within the enterprise. Employees appreciate and cooperate with each other, eliminate the gap between departments and the distance between superiors and subordinates, share information, and achieve effective communication.   3. Use the mental model flexibly, learn to give up, not try to prolong, learn to improve, that is, constantly surpass yourself.   For some products, enterprises will have to give up on a planned basis rather than try to prolong the life of products or businesses. Some hydraulic manifolds, including plated hydraulic valves. When AAK produced hydraulic valves 13 years ago, there was also a production line for plated valves, but after the production of hydraulic manifolds, AAK resolutely abandoned the plated valves, and focused on the hydraulic cartridge valves. The total quality management and lean production of Japanese manufacturing industry are aimed at their best products. The world invisible champion of German enterprises also focuses on the familiar part.   5 years ago, AAK Hydraulic Manifold hired workshop manager from the Japanese manufacturing industry to directly guide and lead the employees on the production site. We clearly saw the improvement of quality and efficiency, and clearly felt the effect of process improvement and capacity release. More importantly, the technicians were stimulated. Using knowledge flexibly can change our way of thinking. Practice with practical actions, find problems, solve problems, and strive for satisfactory results.   AAK Hydraulic Manifold is good at innovation, and can also face failure bravely, but it will always move forward in imbalance. https://www.aakindustry.com/info , -detail/hydraulic-manifolds-aak480

Jimmy is from a hydraulic equipment company in the United States. He has cooperated with AAK for more than 2 years and is very sticky about the quality of hydraulic relief valves. At the end of last year, the hydraulic pilot operated relief valve used in the hydraulic unit they developed could only be purchased from local manufacturer because of tight time. Problems were encountered in the hydraulic manifold installation. The existing hydraulic relief valve of the American factory occupied a little position of the motor, resulting in difficulties in the installation of the motor. If the position of the hydraulic relief valve is changed, the manifold oil circuit will be changed and the power supply of the hydraulic system will be affected. The manufacturer of the hydraulic pressure relief valve has no time to adjust the size. Jimmy had to look for other manufacturers of hydraulic pilot operated relief valves. After a week, he found more than 10 local manufacturers of hydraulic relief valves in the United States. Some of them were not willing to customize it due to small quantity, while some gave no reply at all. Jimmy was very helpless. Jimmy thought of AAK Hydraulic Valves in Ningbo and asked how long it would take to produce 10 non-standard hydraulic pilot operated relief valves? I felt his anxiety and asked if he had encountered any difficulties in purchasing hydraulic relief valves. Only then did he tell me the embarrassment he had encountered in domestic manufacturers in the United States. According to the drawings and manifold schematic diagram of the hydraulic pilot operated relief valve provided by him, AAK engineers also suggested that the hydraulic pilot operated relief valve should be redesigned to reduce the length of the hydraulic pressure relief valve by 35%. AAK can send 10 hydraulic pilot operated relief valves within 30 days. Their engineers doubted this innovation, because if the size is reduced by 35%, the load of the hydraulic pilot operated relief valve will be affected. We understood the concerns of their engineers. We would see the result in a month. If AAK hydraulic relief valve can not solve the problem of the manifold installation, we were willing to bear the loss. Jimmy was waiting for the sample of AAK with worry. After the samples were sent out, we soon received email from Jimmy. AAK newly designed hydraulic relief valve was successfully installed into the manifold, and the equipment commissioning was normal. Their engineers were satisfied. They were curious to know how AAK hydraulic pilot operated relief valve was reduced by 35% under the condition of ensuring parameter. AAK adjusted the size of the spring chamber of the hydraulic pilot operated relief valve, and used Smalley wave spring which has smaller size and can be put into the smaller spring chamber of the hydraulic relief valve. The wave spring adopts the winding process. It is a thin circular springy metal element composed of several wave crests and troughs along the circumferential direction in a sinusoidal form, can withstand large loads even with a small amount of deformation, and the force is symmetrical. Thus, the length of the hydraulic pilot operated relief valve can be shortened. AAK hydraulic pilot operated relief valve, has unique skills to solve the problem that American manufacturers can not do. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak253

This week, we’d like to introduce a hydraulic counterbalance valve equivalent to SUN CBCG, the counterbalance valves with pilot assist are meant to control an overrunning load. 3 months, we received an inquiry from a new customer from the Europe for a hydraulic counterbalance valve equivalent to SUN CBCG. After quoting, we were advised that AAK price is not competitive. Yes, many hydraulic cartridge valve manufacturers in China have this hydraulic counterbalance valve CBCG in stock, so the price competition is very fierce. However, not every manufacturer is able to produce the same quality as SUN, while AAK’s quality has been the supplier of SUN for 5 consecutive years. Our quality has been approved by market. After knowing above, this European customer placed a trial order of 10 pcs with AAK. We are confident that this new European customer will become a long-term partner of AAK very soon.   AAK hydraulic counterbalance valve E-CBCG two advantages: 1. The function and performance is equivalent to that of SUN CBCG 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-CBCG hydraulic counterbalance valve: Max. Operating Pressure: 350 bar (5000 psi) Flow: 15 gpm (60 L/min) Internal Leakage: 5 drops/min Cavity: T-11A AAK E-CBCG hydraulic counterbalance valve, benchmarking SUN CBCG, its service life is 2 times that of its domestic peers. You are welcome to give it a try. AAK HYDRAULIC CARTRIDGE VALVES (778) 2024-02-12 https://www.aakindustry.com/info , -detail/counterbalance-valves-aak778

Demetrius comes from a hydraulic equipment manufacturing company in Greece and has been purchasing hydraulic cartridge valves from China for 2 years. In the second half of last year, a hydraulic cartridge valve with high requirements for all parameters made him very upset. Their company's newly developed hydraulic unit did not go smoothly in the testing, and the hydraulic cartridge valve purchased by Demetrius had a pressure holding time of only 1-4 weeks. The root cause was either this parameter did not meet the standard or that parameter did not meet the standard. The original hydraulic cartridge valve manufacturer tested 3 times but still did not meet the standard. Time has been wasted for more than half a year, and the engineer complained to the boss. Demetrius was very anxious. Demetrius found AAK and contacted us. After communication, we learned that he had encountered difficulties in purchasing hydraulic cartridge valves. Based on the parameter requirements provided by Demetrius for hydraulic cartridge valves, AAK engineers analyzed and found that this hydraulic cartridge valve has high requirements; Close attention needs to be paid during the durability testing. I told him that not only the production of this hydraulic cartridge valve is very important, but also the testing on the various parameters of the hydraulic cartridge valve is also very important. Most hydraulic cartridge valve manufacturers do not pay attention to the testing process, resulting in unstable performance of hydraulic cartridge valves. After 50 days, 30 hydraulic cartridge valve samples from AAK were sent out. Last week, Demetrius informed us via email that their engineers have approved each parameter of the AAK hydraulic cartridge valve, and their hydraulic unit has been delivered to the customer. It is likely that they will receive a batch order. Each parameter of the AAK hydraulic cartridge valve can meet the standard, it is because that while the manufacturing quality is being rigorously improved, the performance and function of the hydraulic cartridge valve are also being tested without negligence. For this hydraulic cartridge valve, AAK uses a multifunctional hydraulic valve testing equipment specially customized by Chufan Hydraulic. We operate it as follows: first, set the testing parameters requirements for each valve on the computer, and then load the hydraulic cartridge valve into the testing equipment to run for a period of time. After the test is completed, the screen will display the testing results. The pressure range, reversing performance, internal leakage, pressure loss, pressure adjustment range, and pressure and flow stability performance data of each hydraulic cartridge valve will be displayed on the electronic display screen, and the detection results will be automatically displayed in real-time. If there are differences, an alarm will be given to remind. Anything that does not meet the standards will be treated as defective products. Most hydraulic cartridge valve manufacturers in China only rely on manually operated hydraulic test benches for testing, and most of them are manually judged, Sometimes, negligence often leads to individual hydraulic cartridge valve parameters not meeting the standards. AAK hydraulic cartridge valve, focus on manufacturing quality, functional and performance testing, you can also give it a try!

Stephen is from Hi-Force hydraulic equipment manufacturing company in the UK. In the second half of last year, he was promoted to the purchasing manager of Kuala Lumpur Branch due to his excellent work. Within a week of taking office, he met with complaints. A batch of their hydraulic cylinders were noisy and vibrated seriously during operation. The after-sales engineer failed to solve the problem within 3 days. The user was not satisfied. Stephen was a little worried. Stephen browsed an article of AAK on Google: "change the design of the hydraulic directional control valve, the vibration disappeared, and AAK eliminated the Canadian factory at zero cost", and left a message: how to solve the noise and vibration of the hydraulic cylinder? After reading this message, I roughly judged that either the hydraulic directional control valve used had problems or the original design had hidden dangers. We asked Stephen to provide the hydraulic system schematic diagram and design drawings, and AAK engineer judges that the working principle of the hydraulic cylinder is reasonable, only by checking on site can we find out the source of the vibration, and then no news from Stephen. 2 weeks later, Stephen emailed that according to the last case that AAK solved the vibration of the hydraulic cylinder, they also added a triangular throttling groove to the hydraulic direction control valve, but after installation, the hydraulic cylinder still vibrated. Their engineers said that AAK solution was a lie. I was speechless and didn't want to explain anything, so I ignored him. 3 days later, Stephen emailed us again, and sent a video of the hydraulic cylinder working and asked our help to check. AAK engineers found that the hydraulic cylinder will emit rhythmic noise and vibration whenever the load drops in the actual work, and preliminarily judged that there is a problem with the hydraulic direction control valve. AAK technical team discussed again according to the drawings, the working principle diagram of the hydraulic cylinder and the working video of the hydraulic cylinder, and confirmed that the problem lies in the hydraulic direction control valve. I told him that AAK could redesign the hydraulic directional control valve and asked him to send us samples of the original hydraulic directional control valve. Stephen may have no choice but promised. 5 days later, we received the sample of the original hydraulic directional control valve, which confirmed the judgment of our engineers that the internal leakage and external leakage of the original hydraulic directional control valve was reversed. 1 week later, AAK sent the newly designed external leakage type hydraulic directional control valve. Stephen informed by email that the noise and vibration problems of the hydraulic cylinder had been solved after using AAK external leakage hydraulic directional control valve. In the past 4 weeks, their engineers, from suspicion, disdain to admiration, wanted to know how AAK engineers found and solved problems, and sent out new hydraulic directional control valves in only 1 week. When the load of the hydraulic cylinder moves downward, the pressure at the oil inlet of the hydraulic directional control valve is pushed higher due to the action of the needle valve. At this time, the control oil inlet is still the original set pressure. Under the action of the oil inlet pressure, the hydraulic directional control valve will be closed. When the oil inlet pressure drops, the hydraulic directional control valve will be opened again. The repetition of this process leads to the vibration and noise of the hydraulic cylinder. That is, the reason for the problem lies in the selection of hydraulic directional control valve. It is only necessary to change the internal leakage hydraulic directional control valve into the external leakage hydraulic directional control valve. Just a while ago, a Canadian customer also ordered the same type of external leakage hydraulic directional control valve, and we have existing samples, so they were sent out soon. Their engineers have to sigh that AAK has too many customer cases, which is true and can really solve the problem. Stephen also privately informed us that his boss was very satisfied with his attitude and spirit to solve the problem this time, and his colleagues in Kuala Lumpur Branch admired him. AAK hydraulic directional control valve, no noise, no vibration, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valve- aak252
