Mechanical Hardware

Since the epidemic, many work forms have changed. Whether working at home or in 3 + 2 mode, it tells us that the future organization will be a new mode, and the manufacturers of hydraulic valves are no exception. My understanding of the future factory is that the factory is a factory, only a limited production department. Just like our hydraulic valve factory in Cixi, it has only one function - producing hydraulic valves, which is the "1" in the "6 + 1" industrial chain. For hydraulic valve industry, "6" in the "6 + 1" industrial chain refers to: 1) hydraulic valve design and innovation, 2) procurement (raw materials, or semi- finished products), 3) warehousing and transportation, 4) order processing, 5) hydraulic valve sales, 6) after-sales and service; "1" refers to the production of hydraulic valves. A few years later, our hydraulic valve factory is no longer crowded. The hydraulic valve workshop is either the sound of machine tool cutting metal, or 2-3 masters who give machine tool instructions or maintenance. Small bosses shouldn't care about the macro-economy, which has nothing to do with you and me. Just like me, you can focus on a subdivided field of hydraulic valves, and it is enough to achieve the top 1% in this field. Please note, it is not Top 1. AAK has always focused on the single product of hydraulic valves. It works online for 4 hours a day, which is 7,300 hours in 5 years. It has reached the top 1% of the subdivided field of hydraulic valves. If your enterprise can't reach the top 1%, add another 2 years and reach 10,000 hours in 7 years. You must be the top 1%. Seven years is a watershed for many enterprises. Seven years later, if your enterprise is still "poor", there must be problems in your cognition, thinking and method. The "conspiracy theory" on the Internet makes those with simple brains look less simple. Online "knowledge fast food" makes those who never "think deeply" look like they can "think deeply". This is not a good way to do the hydraulic valves. Online, our circle is no longer restricted by the actual conditions and regions, and it is easier for those with similar interests to gather together. Although you may be in completely different industries, or even you and I are far from each other, the same combination of "cognition" and "Three Reviews" makes you attract each other. AAK hydraulic valves adhere to our three views and the top 1% of the industry. AAK hydraulic valves adhere to a group of people, a lifetime and one thing, let each user use AAK hydraulic valves without any trouble. AAK hydraulic valves adhere to the principle of integrity, does a good job in the business of AAK hydraulic valves, and sincerely treats the customers who purchase each hydraulic valve. Let more customers use good hydraulic valves with real materials without wasting money. AAK hydraulic valves, top 1%, welcome to give it a try. https://www.aakindustry.com/info-detai , l/hydraulic-valves-aak194

13 years ago, because of poor, I chose to start a business. I chose the hard hydraulic cartridge valve manufacturing industry, not because I had resources or love, but because I wanted to make some money. Because there were not many manufacturers engaged in hydraulic cartridge valves in Ningbo, I thought this is an opportunity. Today, Saturday at 06:00am, after a few laps outside, the light rain ticked, and I felt that although spring had come, winter was still here. Thinking in the rain is both a repetition and a whim, so I have a summary of 13 points in the manufacturing industry of hydraulic cartridge valves over the past 13 years. Perhaps you have the same feeling. Let's come together. 1. Motivation for engaging in hydraulic cartridge valves: Due to poverty, there are not many foreign trade companies engaged in hydraulic cartridge valves, and there are fewer cartridge valve manufacturers that do well. 2. The future of AAK hydraulic cartridge valves: Don't think about it, just think about what I should do now, with high efficiency and better results. 3. AAK hydraulic cartridge valve information releases: Don't be too much, just focus on what the target customer wants, the more specific the better. 4. Communication with peers of hydraulic cartridge valves: Communicate with high-quality customers and peers, and stay away from those in debt. 5. The essence of hydraulic cartridge valve marketing: Customers only focus on benefits, which are the only thing that touches people's hearts. AAK focuses on what benefits it brings to customers. 6. AAK Hydraulic Cartridge Valve Innovation: Don't invent, don't innovate, just innovate related. 7. AAK hydraulic cartridge valve 3 key points: manufacturing quality, function, performance. 8. The logic of online sales of AAK hydraulic cartridge valves: promotion begins with a sense of scale, followed by a sense of familiarity, and finally a sense of trust. 9. Cognition of AAK hydraulic cartridge valve: pre cognitive bias, post cognitive imbalance, the same applies to business. 10. Customers of AAK hydraulic cartridge valves: Introduction from old customers, others from the Internet. 11. Details of AAK: Details are all in skills, including manufacturing, process, technology, material selection, marketing, promotion, and sales. 12. The focus of AAK hydraulic cartridge valves: It has nothing to do with the economic environment, and only cultivates one acre of land of our own. 13. Decision making for AAK hydraulic cartridge valves: When people are short of money or angry, they must not make any decisions. AAK hydraulic cartridge valve, 13 years, 13 thinkings, let's come together. https://www.aakindustry.com/info- , detail/cartridge-valve-manufacturer-aak541

Someone left a message on the hydraulic manifold manufacturer AAK website: Write these about hydraulic cartridge valves and manifolds every day. Does anyone laugh at you? My inner response to messages like this is, don't take yourself too seriously. Although hydraulic manifold manufacturer AAK has been around for 14 years, we are still positioned at the grassroots level. Everyone has their own troubles to deal with, who will laugh at you. Taking yourself too seriously can lead to many things not being done well, or even not being able to do them. In the past year, some praise hydraulic manifold manufacturer AAK, while others criticize hydraulic manifold manufacturer AAK. Praise shows your generosity. Criticize shows your contribution. Both are helping AAK to grow. On the last day of 2023, thank you again for your attention, generosity, and support to hydraulic manifold manufacturer AAK. In 2024, hydraulic manifold manufacturer AAK has arrived.   Hydraulic manifold manufacturer AAK does not pursue the path of diversified and rapid expansion, but deeply cultivates in the field of hydraulic manifolds subdivision, achieving "one finger wide, one kilometer deep", focusing on small and beautiful, striving to inherit like German enterprises, insisting on the stability of technology and the rigor of technology, and providing value to customers. This is the tomorrow of hydraulic manifold manufacturer AAK. Today, on the last day of 2023, I am presenting a regulatory annual report from hydraulic manifold manufacturer AAK to every friend who is interested in it. 1. 365: A total of 291 tweets and 74 videos were published annually on the AAK website. 365 days in a year, we dare not rest for a single day. Conservatively estimated, over 220,000 words were output in one year.   2. 86: Every day on 86 B2B platforms, release AAK hydraulic manifolds and hydraulic cartridge valve tweets.   3. 323: We have received a total of 323 messages this year for AAK hydraulic valves website or various B2Bs.

Regardless of the overall environment, we must have an optimistic outlook on the future and have confidence in the development of the hydraulic industry. Never complain, only check your own problems. Beyond the perseverance of those around us, take action every day. Most people regard those who move only one step and have accumulate constantly as clumsy and foolish, believing that there must be a shortcut to success. Unfortunately, they have taken a lifetime's shortcut only to find that it is the farthest path. Hydraulic manifold manufacturer AAK focuses on the network, serving customers who value quality and trust AAK. 2024 is here, life is like flowing water, there is no need to compete for priority, the competition is continuous. Hydraulic manifold manufacturers should care about who can live longer. There is no need to worry too much about the gains and losses of one city or one pool, and hydraulic manifold manufacturers should not compete for every order. What about failing the college entrance examination? You don't see many top scorers in the college entrance examination, disappearing into the crowd without a trace. Fighting is perseverance, and the winner of life is the one who laughs to the end. Similarly, we should not mock a fat man running, as long as he has a firm belief, one day he will amaze everyone. Hydraulic manifold manufacturer AAK is not playing tricks. One finger wide and one kilometer deep, I have been on the road always.

Last October, Henry had planned to go to Hawaii with his family for a vacation. The day before he left, he was informed that a customer complained about the vibration problem of his company's hydraulic power unit during low-speed operation. The boss asked Henry to solve the problem immediately. As the purchasing manager of the company, he had to cancel the annual leave. The engineer tested the hydraulic system on site and preliminarily judged that the hydraulic counterbalance valve was abnormal. The engineer disassembled the hydraulic counterbalance valve and failed to find out the reason. The hydraulic counterbalance valve was tested separately, and each parameter was up to standard. Henry began to contact the local hydraulic counterbalance valve supplier and wanted to solve it as soon as possible, but there was no reply. Henry found the original hydraulic counterbalance valve manufacturer. The factory said that he OEM the hydraulic counterbalance valve completely according to their hydraulic counterbalance valve drawings. He also specially retested the hydraulic counterbalance valve in stock, and its parameter basis was qualified. Henry was embarrassed to face such a situation. Henry thought of AAK because we helped him solve the difficult problems of hydraulic counterbalance valves several times before. We received Henry's email and understood that neither the original manufacturer nor the local manufacturer provided solutions. According to the working video of the pressure unit provided by Henry, our engineers recognized their preliminary judgment that the hydraulic counterbalance valve was abnormal. The function of the hydraulic counterbalance valve is to balance the "negative load force" opposite to the required movement direction, which makes the hydraulic motor easier to control. The vibration problem in the complaint is that the hydraulic counterbalance valve affects the control ability of the balance circuit to the load. This is just our first surmise about the fault. The specific situation needs to be determined in combination with the actual hydraulic counterbalance valve samples. Henry sent us the hydraulic counterbalance valve samples the next day. After our engineers disassembled it, we are 90% confident that our judgment is correct. The check valve throttling groove of their hydraulic counterbalance valve is a traditional design. According to the working condition of their pressure unit, the design of double triangular throttling groove of hydraulic counterbalance valve has a little influence on the stability of valve spool. The hydraulic counterbalance valves we shipped to a Russian customer 2 years ago also encountered similar problems. I suggest Henry redesign the structure of the hydraulic counterbalance valve. A month later, AAK sent out 10 samples of hydraulic counterbalance valves, Henry installed the equipment for commissioning, and there was no vibration problem. AAK engineers changed the design of the check valve throttling groove of the hydraulic counterbalance valve from double triangular throttling groove to independent triangular throttling groove. The overflow area of the throttling groove, the internal fluid flow of the check valve spool and the dynamic characteristics of the balance circuit were compared and analyzed. Finally, it was determined that the triangular throttling groove had a much smaller impact on the stability of the valve spool and the system than the double triangular throttling groove. Henry sent me photos of a happy vacation in Hawaii and thanked AAK for solving the problem professionally. His boss was very satisfied with his quick solution to the problem and specially gave him two more days off. He was very happy. AAK hydraulic counterbalance valves, your problem today may be the road I walked yesterday. You can have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valves-aak193

Several hydraulic cartridge valve manufacturers in Ningbo China have been in the same industry, and they all know that I enjoy reading. Turning a few pages at the bedside every day is a compulsory course for me. Reading in the study in the morning is my first action every day. Some hydraulic cartridge valve manufacturers believe that the problems encountered with hydraulic cartridge valves cannot be solved by reading. I know this, but if you don't read, you won't even be able to detect problems. That is why many hydraulic cartridge valve manufacturers in the same industry always think their service is very good, but customers are not satisfied. Most hydraulic cartridge valve manufacturers in the same industry are not able to identify their own problems. Reading is not about letting hydraulic valve manufacturers know anything, but about understanding what else they don't know. On average, I have to finish 1 book per week. Most of the books that I read some years ago have been forgot after some years later. My colleagues from hydraulic cartridge valve manufacturers laughed at me. So what is the meaning of reading? Just looking for something you don't know? Of course not, the answer is already in the book. When I was a child, I ate a lot of food and now I can't remember what I ate. But what is certain is that some of them have grown into my bones and blood. Reading is like the food I have eaten, and it also changes people. The books you have read, the experiences you have experienced, after a long time, you forget all the details, and the rest becomes your cultivation. Not all the books you have read may be remembered, but they will remain in your heart. Hydraulic cartridge valve manufacturer AAK has to face different customers. With this cultivation, it can make you speak with reason, have room for action, speak with scale, and play with moderation. Your speech and behavior are all precipitated by your reading, and it will unknowingly change your entire life. Reading and earning money are the best practices in life. The former is not confusing, while the latter gives people dignity. AAK uses the industry experience of hydraulic cartridge valve manufacturers to study, and uses the results of reading to become a leader in hydraulic cartridge valve manufacturers, serving hydraulic cartridge valve customers. Hydraulic cartridge valve manufacturer AAK, earns a little money during the day and reads some books in the morning. In the temperament obtained from reading, there will be hidden books that have been read, roads that have been passed, and people who have loved. Hydraulic cartridge valve manufacturer AAK, has always been with you.

Brighton is from Brazil and has cooperated with AAK for 3 years. Most of the orders are for non-standard customized hydraulic cartridge valves. At the beginning of this year, he inquired about a hydraulic cartridge pressure control valve of HydraForce standard parts, and advised that AAK price was 20% higher, then no further updates. I guessed either he didn't get the order, or he gave it to another hydraulic cartridge pressure control valve manufacturer, and I didn't follow up for the status. In October, Brighton sent an email to inquire about this hydraulic cartridge pressure control valve again. After communication, I learned that Brighton chose a hydraulic cartridge valve manufacturer that was 20% cheaper than AAK to place the order at the beginning of the year. However, more than 8 months later, customers complained that the hydraulic cartridge pressure control valve was leaking or stuck. However, the manufacturer did not offer good after-sales service, which made Brighton embarrassed and regretted being greedy for cheap. Brighton returned to AAK, and requested the valve service life to be no less than 16-24 months. I joked that, during the 3 years of cooperation with AAK, did you see any AAK hydraulic cartridge valve with a service life of only 1 year? It is a fact that AAK hydraulic cartridge pressure valve is 20% more expensive, but its service life is twice that of its peers. After 1 week, Brighton sent the PO for 360 hydraulic cartridge pressure control valves, and specifically mentioned that his boss was interested in the service life of AAK hydraulic cartridge pressure valve being twice that of peers, not that the price was 20% higher than that of the original manufacturer. I told him that the price of AAK hydraulic cartridge pressure control valve was 20% higher, not only because the raw materials and accessories were 1-2 grades better than those used by peers, but also the heat treatment of metal parts was great, and special components used AAK personalized heat treatment process. The heat treatment process is carried out under vacuum, including quenching, annealing, tempering, carburizing and nitriding. This heat treatment process has 3 advantages: 1. When heated under vacuum, the metal elements will not be oxidized, decarburized or carburized, the surface finish will be improved by at least 30%, and the strength of steel parts will also be improved, making them more wear-resistant. 2. Under vacuum heating, the hydrogen in the metal is rapidly reduced to the minimum, eliminating hydrogen embrittlement, improving the plasticity, toughness and fatigue strength of steel, and the overall mechanical properties of the components are more conducive to the life of the hydraulic cartridge pressure control valve. 3. The furnace is heated by thermal radiation, the temperature difference between inside and outside is small, and the quenching under vacuum ensures that the hardness of each element is consistent, which is also conducive to the service life of the hydraulic cartridge pressure control valve. AAK hydraulic cartridge pressure control valve is 20% more expensive, but its service life is twice that of its peers.

Back from the three-day holiday, the director of the machine tool workshop sent a production report of TRV-08 hydraulic direct acting relief valve for an Indian customer early in the morning. The first paragraph is like this: "the programmers in our workshop made a low- level mistake and compiled the leakage of 2 drop / min in the hydraulic direct acting relief valve into a production process of 5 drop / min. I didn't check it out because I was anxious to go back to my hometown for the holiday". Seeing this production report of TRV-08 hydraulic direct acting relief valve, I was angry, not because the hydraulic relief valves produced has to be wasted, but because the workshop director indicated it as a low-level mistake in order to whitewash it. In every production link of hydraulic valves, error is error. There has never been any low-level error or high-level error. As long as you make a mistake, it's either bleeding or dying. I replied to him: 1.Re-produce TRV-08 hydraulic direct acting relief valve and work overtime continuously to make up for the the production progress delayed for 3 days. The produced parts of hydraulic relief valves shall be put into the waste warehouse and registered. 2.In the production of hydraulic valves, if you will make a mistake that no one has ever made, you can be promoted from workshop director to production director. The thought of predecessors is the ladder of future generations. To experience the pain of bleeding from mistakes, you can grow. No matter the production programming of hydraulic direct acting relief valves or other production links of hydraulic direct acting relief valves, we should not be careless. AAK hydraulic relief valves, it doesn't matter if there is a mistake. First recognize the mistake, then correct yourself, and then protect customers. You are welcome to try an order with AAK. https://www.aakindustry.com/info-detail/hy , draulic-relief-valves-aak192

For the leakage in the pilot-operated pressure control valves less than 2drops /min, Howard from Accupress in Canada, contacted more than 30 Chinese hydraulic valve manufacturers. Only AAK pilot-operated pressure control valves met the standard and replaced his local factory in the United States. Last year, the hydraulic shearing machine they listed sold well. The boss decided to mass produce it in Suzhou, China. However, the pilot-operated pressure control valve to be used in the hydraulic shearing machine was originally purchased in the United States, and the internal leakage is less than 2drops / min. If the pilot-operated pressure control valve is purchased from China, it will save money and time. While contacting some old suppliers, Howard is also looking for new manufacturers of pilot-operated pressure control valves. We also received Howard's inquiry. The email subject is: can you supply pilot- operated pressure control valves with internal leakage less than 2drops / min for our Suzhou factory? We thought it was a domestic purchase, so we politely refused. Until Howard's second email told us why he wanted to ship to Suzhou, and he contacted more than 30 Chinese hydraulic valve manufacturers, only two of them replied that they could try to make samples of pilot-operated pressure control valves with internal leakage less than 2drops/min, and there was no any reply from the other manufacturers. Howard asked if AAK pilot-operated pressure control valves could meet American factory standards? If not, the sample is meaningless. I told him directly that AAK had tested samples of pilot-operated pressure control valves with internal leakage less than 2drops/min for a German company some time ago. The pilot- operated pressure control valves can be refunded in full if our samples do not meet the standard. One month later, 30 pilot operated pressure control valves were sent to Accupress's Suzhou plant. Four weeks later, Howard sent an email saying that their engineers tested the pilot operated pressure control valves of AAK and two other manufacturers, and only AAK samples met the standard. Some parameters were higher than those of the original American factory, and those of the other two manufacturers did not meet the standards. In particular, AAK pilot operated pressure control valves caught up with and surpassed his American factory, which surprised him. AAK pilot operated pressure control valves can meet such requirements because of two reasons: 1、For the pilot operated pressure control valves, the matching clearance accuracy between the valve spool and the valve body directly determines the internal leakage of the whole valve. AAK has German Nagel precision honing machine. After honing, the dimensional accuracy of the cone plating of the valve spool and valve body of the pilot operated pressure control valve is IT7 ~ 4, and the surface roughness can reach Ra0.32 ~ 0.04μm, which can not be achieved by most of hydraulic valve manufacturers. 2、After assembly, AAK uses a special air pressure tester to detect the leakage of each pilot operated pressure control valve. Within the set pressure and time range, AAK judges the internal leakage according to the number of bubbles. However, most factories use the oil pressure test method. As I have known that there may be no more than three factories that can use special air pressure test. Howard told me privately that his boss appreciated his quick finding a supplier who could replace the pilot operated pressure control valves produced in American factory. Now his purchasing authority has been improved. AAK pilot operated pressure control valves, the internal leakage is less than 2drops /min. You are welcome to have a small try! https://www.aakindustry.com/info-detai , l/pressure-control-valves-aak191

5 years ago, engineer Mr. Liu worked at a hydraulic manifold manufacturer for 3 years before going to Japan for further studies, and then worked in SUN's China office for 2 years. Last week, engineer Mr. Liu approached me and wanted to start a new hydraulic manifold manufacturer. I know his technical skills can support a hydraulic manifold manufacturer, but a new hydraulic manifold manufacturer should not only focus on technology, but also consider the direction, business model, team, and product positioning of the hydraulic manifold manufacturer. I told engineer Mr.Liu that the choice was wrong and the effort was in vain. The direction is wrong, the harder you work, the more helpless you become. You don't necessarily have to focus on hydraulic manifolds, you can also make hydraulic valves and hydraulic motors. On the road to entrepreneurship, even a tech giant may not have smooth sailing. I shared how hydraulic manifold manufacturer AAK came step by step back then. The 1st level of AAK is to determine the direction. AAK has chosen hydraulic cartridge valves, which are the core components of hydraulic manifolds. In fact, most hydraulic manifold manufacturers start by producing manifold blocks, and then the core components - hydraulic cartidge valves are purchased externally. The 2nd level of AAK is creating models. The most important point: Who do you plan to do business with? Find out who your target customers are and who your competitors are. AAK is positioned as a customer group with quality standards and a focus on online platforms. By leveraging AAK's strengths and characteristics, we aim to establish customer trust online. At that time, most hydraulic manifold manufacturers only engaged in offline business, and domestic business relied on relationships or low price competition. The 3rd level of AAK is team building. All careers are created by humans. Initially, hydraulic manifold manufacturer AAK established a team based on 4 conditions: mutual trust, complementary capabilities, clear division of labor, and financial support. The 4th level of AAK is polishing the product. At the beginning, we treated SUN and HydarForce as benchmark objects, bought many of their hydraulic cartridge valves to disassemble, extracted each part of the hydraulic cartridge valve, materials used, technology, precision requirements, etc., and specified a production process sheet that meets the requirements of hydraulic manifold manufacturer AAK. Most hydraulic manifold manufacturers only focus on the surrounding factories, focusing on how to save costs and obtain orders. The 5th level of AAK is trust building. We focus on the online to tell customers what are the products of hydraulic manifold manufacturer AAK? What's the difference? How can we see this? How to make it easy for customers to see and remember you online. The 6th level of AAK is to give benefits. Most customers pay for the benefits, and AAK spreads online to attract new customers, while the core is how to bring value to existing customers. Most hydraulic manifold manufacturers are attracting new users while losing old ones, and this is the most taboo of hydraulic manifold manufacturer AAK. The 7th level of AAK is to lead a team. When the horn blows, the troops must keep up. For example, can AAK produce products that most hydraulic manifold manufacturers do not want to produce? For example, can AAK handle products that most hydraulic manifold manufacturers cannot handle? The basic qualities for doing business are reliability and turning "impossible" into "possible". Entrepreneurship is about achieving definite results in an uncertain environment. The journey of hydraulic manifold manufacturer AAK is not easy, difficult, and only we know it ourselves. Tired, tired, tired, still endure. AAK HYDRAULIC VALVES (747) 2023-12-30 https://www.aakindustry.com/info , -detail/hydraulic-manifold-manufacturers- aak74 , 7

Davis is an old customer from Germany. We met 3 years ago and he purchases hydraulic valves from AAK every year. In the second half of last year, Davis suddenly asked me: can AAK hydraulic valve blocks be as stable as the hydraulic valves? I feel that there is a problem with the hydraulic valve blocks he purchased from other manufacturers. According to the hydraulic valve block drawings sent by Davis, AAK engineers found that this hydraulic valve block is indeed difficult after review. In particular, the oil passage width of the hydraulic valve block is more than 2 times smaller than that of the conventional one, and some valve spool holes are multi segmented structure, which has high requirements for hydraulic valve block processing and iron filings cleaning. I told Davis that you will see the results in 40 days. One month later, AAK sent 5 samples of hydraulic valve blocks as scheduled. Strangely, 2 months later, there was no news from Davis about this hydraulic valve block. After a lapse of more than half a year, that is, last week, Davis sent an email to purchase 1,000 hydraulic valve blocks at one time. The stability of the hydraulic valve blocks must not be lower than that of the samples sent half a year ago. More than half a year has passed since proofing, suddenly, an order of such a big quantity for hydraulic valve blocks have been placed, which makes us happy and surprised. Davis informed that the hydraulic valve block samples provided by AAK have been tested internally. Half a year later, their engineers thought that the hydraulic valve block samples provided by AAK had passed the test, so they placed a large order of hydraulic valve blocks today. In fact, this is not their new order, but moved from the original hydraulic valve block manufacturer to AAK. The original manufacturer started shipping 2 years ago, but during these 2 years, users always complain that the burr of the hydraulic valve blocks pollutes the oil. Sometimes the burr of the hydraulic valve blocks causes the hydraulic valves to jam, which makes their after-sales personnel very embarrassed. They also tried to ask more than 20 new manufacturers of hydraulic valve blocks for solution, but none of them can guarantee 100% free of iron filings. They can only continue to purchase this hydraulic valve block from the original manufacturer. The boss was very unhappy and gave Davis half a year. If the burr problem of the hydraulic valve blocks cannot be completely solved, they can only purchase domestically from Germany in the future, even if the price is more than 60% expensive. AAK hydraulic valve blocks have withstood the test for half a year and Davis also completed the task given by the boss. Davis was also surprised. Later, he asked me: Why can't the original manufacturer solve it for 2 years and more than 20 manufacturers can't guarantee it 100%. How can AAK hydraulic valve blocks be 100% burr free? 1. AAK adopts German Alma ultrasonic, which is a sharp deburring tool. Its instantaneous high pressure can effectively remove the burr of the inner hole of the hydraulic valve blocks. 2. Then use the industrial endoscope to check all the hydraulic valve block channels again to ensure that there are no dead corners. 3. Then observe the inner hole of each hydraulic valve block with a high magnification microscope to ensure that it is 100% free of burrs and other impurities before packaging. AAK hydraulic valve blocks have unique skills in deburring. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak190

Alek is from Poland and was annoyed when he first purchased hydraulic cartridge valves from Ningbo. In the second half of last year, they tested a hydraulic lift that used a hydraulic cartridge counterbalance valve purchased from a hydraulic cartridge valve manufacturer in Ningbo. When the load was lowered, the lift vibrated at low frequencies and the system was unstable. The customer was not satisfied with the prototype and requested that the hidden danger be resolved within 2 months, otherwise the order would only be cancelled. The original hydraulic cartridge counterbalance valve manufacturer reported that this function is a standard model benchmarking SUN Hydraulics and cannot be improved. Alek contacted other hydraulic cartridge valve manufacturers in Ningbo, but after a week, there was no result. Alek was upset. Alek contacted AAK through the introduction of peers. In my impression, AAK seems to have no Polish customers. I joked that your name Alek is very close to my company's name AAK. Perhaps it was God's arrangement to bring us together. According to his introduction, it seems that the SUN standard part of hydraulic cartridge counterbalance valve does not match his equipment system. Due to the inconvenience of changing the system, it is only possible to customize the hydraulic cartridge counterbalance valve to match the system. According to the schematic diagram of the hydraulic system provided by him, the peak pressure generated by load impact is relatively high. If the hydraulic cartridge counterbalance valve is buffered in a timely manner, it should be able to alleviate the vibration. After 50 days, AAK sent 10 samples of hydraulic cartridge counterbalance valves. 3 weeks later, Alek informed me that their lift prototype had been approved by the customer and asked me to wait for further news. 3 months later, yesterday, Alek sent us a PO for 300 hydraulic cartridge counterbalance valve. Their engineers are satisfied with AAK hydraulic cartridge counterbalance valve, the speed at which the lift loads are lowered, is well controlled, and the system is stable. AAK hydraulic cartridge counterbalance valve has no sudden change in the flow area, and can quickly and timely cushion the pressure peak generated by load impact, making the lift safer and energy-saving. 1. The valve seat of the hydraulic cartridge counterbalance valve is provided with a transversely penetrating through-hole, forming a valve seat connecting hole section, a valve seat connecting hole section, a valve seat transition hole section, and a valve seat sliding hole section. The apertures of the 4 hole sections decrease in turn, with a first oil port of the connecting section on the side wall of the valve seat, and a second oil port at the right end of the through-hole of the valve seat. 2. The valve sleeve of the hydraulic cartridge counterbalance valve is provided with a transverse through-hole to form a main hole section of the valve sleeve and a reduced diameter hole section of the valve sleeve. The outer wall of the valve sleeve is provided with a valve sleeve through-flow groove that communicates with the fourth oil port. 3. The valve spool is located in the main hole section of the valve sleeve and can be moved left and right to match the 2 valve spool reducing sections in the valve sleeve reducing hole section. The left side of the second valve spool reducing section is provided with a flange for opening and closing the valve seat transition hole section, and a valve spool throttle hole is located on the right side of the flange. When the pressure oil from the fourth oil port enters the valve spool of the first control chamber, the valve spool moves to the left, gradually exposing each radial orifice, and the overflow area can be reduced and increased. The hydraulic cartridge counterbalance valve can timely cushion the pressure peak generated by load impact. AAK hydraulic cartridge counterbalance valve, has a function that SUN standard part do not have, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-counterbalance-valves-aak540

My friend, a hydraulic cartridge valve manufacturer, his daughter got married today, and invited me to the wedding banquet. Of course, I should bring a red envelope to congratulate him. This friend has been working as a hydraulic cartridge valve manufacturer for 20 years. We are both teachers and friends, and when encountering problems with hydraulic cartridge valves, we consult with each other, unlike other hydraulic cartridge valve manufacturers who without any contact with each other. Seeing his son-in-law, my heart sank. Apart from being handsome, there was more lack of confidence. Later on, I learned that this young man came from a rural area in the central region of China, with both parents being farmers and a relatively poor family. My friend's family, after all, has been a hydraulic cartridge valve manufacturer for more than 20 years and is considered wealthy. They only have one daughter. The marriage in China is more about "matching families". Marrying a family without money really worries me about my friend's daughter. The old Chinese saying goes: When getting married, if you are favored by wealthy people, you must marry the wealthy instead of the poor. Rich people have many choices but still want to be with you because they really love you, while poor people are with you because they have no choice. Although I don't quite agree with this paragraph, I am powerless to refute it. Younger people may think that this viewpoint is too secular and snobbish. When they get older, they may understand, but it's too late. Love is the romance of two strong people, not the bitter hatred of two weak people. I advise all girls that it is better not to marry than to marry a poor person. This is also established in the hydraulic cartridge valve manufacturer industry. I advise all hydraulic cartridge valve manufacturers that it is better to choose not to accept orders than to ship to poor customers. In today's society, if money is not in place, no matter how many advantages, they are also disadvantages. If money is in place, no matter how many drawbacks, they can be ignored. In school, if you are a top student, all other shortcomings can be ignored. If you are a bottom student, no matter how outstanding you are in other aspects, it is useless. Maugham also said: When you marry a poor person, you will be responsible for his ignorance, debts, disasters, and all his misfortunes, wrong thoughts, as well as the ignorance, laziness, and chaos of his family. You will be responsible for it, and with what? Take responsibility for the cost of your life, wealth, career, and future. Marrying a poor person requires personal dedication and the intention to never turn around. Women who marry poor families will suffer the hardships and hardships of life. Both physically and mentally, you will be under tremendous pressure, thinking all day long about how to live a good life, saving money for children to study, unwilling to buy new clothes for yourself, and watching others' faces to work. The girl who originally loved beauty and gentleness was forced by life to become a tough woman. Marriage is not a child's play. When choosing a marriage partner, it is important to keep eyes open. Marriage cannot only focus on money, but it is absolutely not workable without money. The business of hydraulic cartridge valves is not a game. When choosing customers, it should be cautious. Hydraulic cartridge valve manufacturers cannot only focus on money, but it is definitely not workable not to talk about money. Every woman has an opportunity to make herself happy, and this opportunity depends on herself to strive for. Every hydraulic cartridge valve manufacturer has an opportunity to make money, and it is up to them to seize this opportunity. Hydraulic cartridge valve manufacturer AAK, never makes small moves under the table, targets customers who are suitable match, and only accept orders from customers who can afford it.

German customer David has been purchased hydraulic relief valves in Ningbo in a same factory. At the beginning of last year, David purchased a batch of hydraulic relief valves for crane system in AAK because the original supplier was not able to meet the delivery. He sent an email last week saying: "with AAK hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage". This surprised him. The use experience of AAK hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers in Germany. The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of AAK hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does AAK do the sand cleaning of hydraulic relief valves? AAK technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, AAK has its own unique AAK sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. AAK has its own unique advantages of AAK sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is carried out before machining and does not affect the arrangement of machining process; (3) although it has a certain impact on the environment, antifogging agent is added during pickling to reduce the impact. At the same time, corresponding corrosion inhibitor is added during pickling, and rust prevention treatment is carried out immediately after rinsing to ensure the stability of hydraulic relief valves. This is also the reason why the stability of AAK hydraulic relief valves is more than 8% higher than that of other manufacturers. The stability of AAK hydraulic relief valves comes from AAK unique and efficient sand cleaning methods.

Philip comes from a hydraulic equipment company in Italy. He has purchased hydraulic pressure reducing valves in China for several years. He is also an old customer of AAK. At the beginning of last month, Philip emailed that there was a problem with the hydraulic pressure reducing valves he purchased elsewhere at the beginning of last year, and the company had to pay a lot of money after sales. The boss had big disagree opinion on him. After further communication, we learned that in order to reduce the purchase cost by 17%, he did not choose AAK and purchased hydraulic pressure reducing valves from another factory. The crane sold by Philip’s company suddenly increased the load of variable displacement pump during operation, resulting in the control failure of the whole hydraulic system. Under normal circumstances, the hydraulic pressure reducing valve of the variable displacement pump as the emergency safety valve is in the normally closed state. This time, the pressure of the variable displacement pump cannot be released due to the jamming of the hydraulic pressure reducing valves, resulting in the collapse of the system. The customer requests to replace the hydraulic pressure reducing valves on the equipment and compensate the cost of work delay on the construction site. Philip asked the original manufacturer to replace the hydraulic pressure reducing valves. The manufacturer said that the hydraulic pressure reducing valves have been used for more than half a year. The problem of the valve spool sticking is caused by sundries in the hydraulic oil used by the user. At present, this model of hydraulic pressure reducing valves is not in stock, and it will take at least more than a month to re produce. I asked Philip to send me the model and parameters of this style of hydraulic pressure reducing valves. After analysis, AAK engineers found that the hydraulic pressure reducing valves needed by Philip was exactly the same as that ordered by one of our Russian customers last time. We have it in stock. The next day, AAK sent 20 hydraulic pressure reducing valves to Philip by air express. After receiving them, he asked the after-sales engineer to replace it on site. As a result, everything was normal and the crane could operate smoothly. A week later, Philip sent an email saying that thanks to AAK hydraulic pressure reducing valves, which saved the company a compensation. The boss also appreciated AAK for its help and suggested Philip list AAK as their preferred supplier of hydraulic pressure reducing valves. The price of AAK hydraulic pressure reducing valves may be a little higher than that of its counterparts in Ningbo, but you have no worries when using it. AAK knows that the hydraulic pressure reducing valve is the soul of this crane. Therefore, AAK controls the production quality of the hydraulic pressure reducing valves strictly, so that customers can buy it at ease and use it at ease. AAK hydraulic pressure reducing valves have two absolute advantages and has already surpassed its domestic counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and various independent fixtures upgraded and refitted by itself, which eliminates human errors and avoids valve spool sticking and other faults. 2. The independent professional R & D team, combined with unique R & D technology, has realized the personalized customization demand of hydraulic pressure reducing valves, which can not be achieved by 95% of domestic peers. Peter told me privately that his boss asked him to send samples of the other hydraulic pressure reducing valves previously purchased to AAK for quotation. Even if the price is a little expensive, they should also choose AAK hydraulic valves which are more stable. They not only admire AAK's professional analysis ability, but also AAK's ability to solve difficulties for customers in time. AAK hydraulic pressure reducing valves, professional and whole-hearted, help customers solve problems in time. You are welcome to have a small try. https://www.aakindustry.com/info-detail/hy , draulic-pressure-reducing-valves- aak188
