The gap between grass roots is not cognition, but the skill of making money. The gap between the elite and the elite is not skills, but the perception of making money. I have always positioned myself as a grass root and have been in the hydraulic valve industry for 14 years. Now I don't need to worry about the production workshop and there is a team for technical innovation. I need to constantly learn network skills and improve the network salesperson of AAK hydraulic valves. Over the past a few years, I have achieved little and I am satisfied.   At present, in most online businesses, most salesmen hope to use a detail page to burn advertisements. Anyway, the money is the boss's, not his (her)'s. If there is no customer coming, the responsibility lies in the company, and it has nothing to do with him or her. There are not a few people who have this understanding and attitude, and they have reached a consensus. This is a lazy government in function. Lazy politics is one of the corporate cultures, which is hard to reverse. It seems that online marketing is the responsibility of advertising, and the boss is unlucky.   AAK hydraulic valve online business, is to do a lot of things online, will slowly have inquiries. Most of the time, even if you have done a lot of things, you must do the content right, which is what customers want to see and need to see. On the contrary, if the content is wrong, the effort will be wasted. Do it every day. You must do it every day. If you don't do it, you will get 100,000 why’s. Once started, there were only 3-5 questions left. There is only one reason for endless questions – you don’t do it.   AAK hydraulic valve is not directly oriented to the consumer market, but mostly oriented to enterprise customers. For a long time, AAK has been focusing on the production technology and process of hydraulic cartridge valves, benchmarking the global leader in the hydraulic industry. The invisible champion enterprises in Germany often inherit several generations, and do not pursue the road of diversified and rapid expansion, but instead dig deeply into a specific field, achieve "one finger wide, one kilometer deep", and accumulate deep technical reserves and stable market channels. This is the future of AAK hydraulic valves.   Today is the last day of 2022. I always feel that I can't say enough. I'm worried that there is no logic. I still use rules to summarize the year of AAK hydraulic valves. This is also an annual report of AAK hydraulic valves to everyone who is following AAK. 1. 326 - 326 tweets have been published annually on the AAK hydraulic valve website. It is conservatively estimated to be more than 260,000 words.   2. 86 - AAK hydraulic valve tweets are published on 86 B2B platforms every day.   3. 341 - In AAK hydraulic valve or B2B, 341 messages have been received this year. As long as it is the right category, we will reply at the first time   4. 277 - We have received 277 inquiries this year, on average, there are inquiries every working day.   5. 142 - New and old customers, cumulative trying sample for 142 items.   6. 67 - In the program library of AAK hydraulic valves, 67 non-standard hydraulic valve customization programs have been added this year.   7. 46 - On the AAK hydraulic valve website, 46 new items were launched   8. 24 - In the customer list of AAK hydraulic valve, there are 24 new customers.   9. 6 - Among the new customers generated, are from 6 new countries.   10. 176 - AAK sent 176 packages this year.   11. 24 - 24 sets of hydraulic manifolds have been customized, and the average sampling time is twice a month.   12. 674 - In the AAK hydraulic valve program library, 674 sets of hydraulic valve standard parts have been accumulated, and the benchmarking is SUN, HYDRAFORCE, HAWE, REXROTH, international brands.   The year 2023 is coming, and there is no new idea. Just keep these 3 points: 1）Be optimistic about the future. Facts have proved that pessimists are absolutely right and optimists are sure to make money. 2）Never complain, just check your own problems. Facts have proved that the practice of muffling and continuous improvement is effective. 3）Go beyond the insistence of the surrounding people and do it every day.   Most people think that people who have been moving one step a day and accumulated continuously are clumsy and stupid. They think that there must be a shortcut to success. Unfortunately, they have taken the shortcut of life, but found it the farthest way. Someone laughed at me. Why does a person engaged in the production of hydraulic valves spend time every day on these tweets? In fact, just as Rolls Royce's advertising must be seen by the public, the public does not have the strength to buy Rolls Royce. However, if the public does not know Rolls Royce, people who drive Rolls Royce will feel that it is meaningless.   The black swan in 3 years may start to turn the page today, and do what you should do next year. I am a person who conforms to the current situation (time and situation). As long as interests do not conflict, I will not contradict what others say. Once people understand, they will become silent. It's not that you don't have the ability to get along with others, but that you don't have the interest to play tricks on the spot.   AAK hydraulic valves do not play tricks. One finger wide, one kilometer deep, I have been on the road. https://www.aakindustry.com/info-deta , il/hydraulic-cartridge-valves-aak457

Connor is a purchaser from a Russian hydraulic company. There has never been oil leakage due to sealing in his previous purchases of hydraulic valve blocks. Some time ago, a rated pressure up to 450bar hydraulic valve block let him suffer due to the oil leakage of the hydraulic valve block. He communicated with the original manufacturer for many times and debugged for 3 times, but the oil leakage problem still cannot be solved. He then asked his other hydraulic valve block suppliers, they all suggested Connor giving up, because the current sealing technology cannot meet the pressure rating of 450bar hydraulic valve block. Connor also communicated with some new hydraulic valve block manufacturers online, and gradually understood the shortage of sealing technology. The 90% of hydraulic valve block manufacturers use the conventional sealing method of hexagon socket plug and sealing combination gasket, which is suitable for hydraulic valve blocks with rated pressure of 50-350bar only. For any over 350bar, this sealing method does not work and they have to give up. Can the sealing problem on a hydraulic valve block with 450bar rated pressure really not be solved? Connor still didn't give up. He found AAK hydraulic valve on B2B and came across an article about AAK hydraulic valve block using Swiss sealing technology to solve the oil leakage of hydraulic valve block. He left a message on our website: can you really solve the problem of oil leakage of hydraulic valve block with rated pressure above 450bar? Seeing this message, I realized that he should have been cheated by other manufacturers before, so he doesn't believe in the new hydraulic valve block manufacturers easily. We replied to him, no matter how much we said, maybe you don't believe it. Simply put, you directly order 1pc of hydraulic valve block according to your drawing. If the hydraulic valve block produced by AAK still leaks oil, we will directly refund you the fee of this testing order. Maybe Connor has no other choice or he sees hope, he agreed our suggestion. 14 days later, he received AAK hydraulic valve block. 2 days later, the test result came out. Their engineers deliberately pressurized it to 550bar, and no hidden danger of oil leakage was found in AAK hydraulic valve block. He wondered why AAK hydraulic valve block had no problem with even a rated pressure at 550bar? The reason that AAK hydraulic valve block can operate normally in the hydraulic system with the pressure of 550bar is because of the introduction of new sealing technology and MB Series Plug of KVT company in Switzerland. This plug mainly forms a solid sealing surface after intermetallic extrusion in the way of expansion and bite, so as to 100% avoid oil leakage of hydraulic valve block, fundamentally solve the problem of high-pressure sealing of hydraulic valve block. At the same time, it reduces pollution, so that the hydraulic valve block is more stable. This is also why Connor recognized the quality of AAK hydraulic valve block. AAK hydraulic valve block, superior sealing, zero leakage, you can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak161

Nestor is from Greece. He has been purchasing hydraulic cartridge valves for 3 years smoothly. A hydraulic directional control cartridge valve bothered him recently. At the beginning of last year, the hydraulic directional control cartridge valve he purchased had leakage, which led to the loss of pressure in the oil circuit of the system. The root cause was the wear of the sealing ring. The original hydraulic directional control cartridge valve manufacturer said that the sealing is a standard O-ring and a single-side PTFE retaining ring, which is an industry standard. If there was a leak, it could only be replaced. It was not acceptable to replace it within 6 months. Nestor realized that this cartridge valve manufacturer was unreliable. Nestor found AAK hydraulic cartridge valve website on Google, noticed several AAK cases about the sealing ring, and left us a message: Can the sealing ring of each hydraulic directional control cartridge valve be guaranteed to be free of wear for 1 year under the high pressure of 350bar? After communication, I learned that he had a problem with the sealing ring of the hydraulic directional control cartridge valve. I replied that regarding the sealing ring, not only the medium but also the material, shape, structure and installation should be considered. Only 5 aspects can be considered comprehensively to determine the most suitable sealing ring. Blind copying of industry standards may lead to leakage. Nestor required AAK samples. After 30 days, AAK sent 20 samples of hydraulic directional control cartridge valves. Last week, Nestor sent an email to inform us that AAK hydraulic directional control cartridge valve has been used for 13 months without any customer complaints about leakage. I told him that there would be no complaints in another half a year. This hydraulic directional control cartridge valve, AAK matches the sealing ring from 5 aspects, and does not follow the industry standard. The sealing ring of AAK hydraulic directional control cartridge valve has unique skills. The outer circumference of the main sealing lip is installed on the inner wall of the valve hole, which reduces the contact area between the sealing structure and the valve hole, reduces the friction between the sealing structure and the valve hole, and increases the service life by at least 2 times. The support ring can reduce the dependence of the hydraulic directional control cartridge valve sealing system on the retaining ring, and avoid the possibility of damage due to improper installation of the retaining ring. 1. Polyurethane material is selected to replace the original rubber material. The plane projection of the sealing ring is circular, and the middle part is a set hole. The inner wall of the sleeve hole is smooth and fits at the bottom of the sealing groove of the hydraulic directional control cartridge valve. High in the middle, low at both ends, symmetrical structure. 2. The shape of the seal ring is high in the middle and low at both ends. It has a symmetrical structure, left, middle and right. The left and right parts have high-strength support rings, and the middle part is the main sealing lip. 3. The support ring makes the cross section of the seal ring in "D" shape, avoiding the possibility of the seal ring being cut by the valve hole during the installation of the hydraulic directional control cartridge valve. AAK hydraulic directional control cartridge valve, sealing ring is controlled from 5 aspects, ensure 18 months of service life without worry, you can also try it! https://www.aakindustry.com/info-detail , /directional-control-cartridge-valves- aak532

Sigal is a Jew, who once again showed me the intelligence of Jews in the business field. Sigal contacted hydraulic manifold manufacturer AAK a week ago, and within a week, he threw 5 questions to the hydraulic manifold manufacturer AAK, and each question becomes more and more tricky. After communication, Sigal disappeared for 5 days, but the PO for hydraulic manifold manufacturer AAK suddenly arrived. Sigal's first question to hydraulic manifold manufacturer AAK is very direct, how much does this hydraulic manifold cost? As soon as we give a quote, he will say it's too expensive. Sigal's second question to hydraulic manifold manufacturer AAK is, do you understand the hydraulic manifold industry? How should I answer this question? I'm a bit confused. I'm a hydraulic manifold manufacturer and I do not need to understand what the industry is all about. Just do a good job in production and manufacturing. If that's the case, it's difficult to get in touch with the client's senior management because they prefer their suppliers to have an understanding of the industry and trends. Sigal's third question to hydraulic manifold manufacturer AAK is, which customers have you worked with? Most hydraulic manifold manufacturers answer this question in the form of a journal. Sigal's fourth question to hydraulic integration manufacturer AAK is, what is the difference between you and other hydraulic manifold manufacturers? Most hydraulic manifold manufacturers start bragging or can't get to the point. Sigal's fifth question to hydraulic manifold manufacturer AAK is, I have learned about AAK. If there is a need, I will contact you as soon as possible When dealing with these questions, we must be based on professionalism. Professionalism means that you can speak what others think in their minds, rather than understanding your own products and services. When customers come to hydraulic manifold manufacturer AAK, they usually compare from two dimensions: either compare AAK with AAK’s competitors, or compare AAK with their competitors' suppliers. What is the solution to Sigal's 5 questions? Most hydraulic manifold manufacturers use what to deal with this type of questions, but rarely think about WHY. Why does Sigal ask you this question? In fact, when he asks you a question, it's just benchmarking. We can also ask questions in reverse. For example, what do you mean? We can't just foolishly tell him what we are different from A hydraulic manifold manufacturer, B hydraulic manifold manufacturer, and C hydraulic manifold manufacturer. Actually, customers may not know who you are competing with or benchmarking against. If you provide hydraulic manifold manufacturer A or B, he will directly go to these peers. My second question to Sigal, which aspect do you pay more attention to? Didn't you ask the difference between AAK and other hydraulic manifold manufacturers? What aspects do you refer to? Sometimes, buyers may not necessarily know about this industry, but they know themselves and can more or less say something. Finally, I replied to Sigal like this. With your words, I have more confidence in cooperating with you. Because the aspects you are concerned about are all very important, and these are exactly what hydraulic manifold manufacturer AAK can do, which also helps you compete with your peers. Meanwhile, we have cooperated with three of the top companies in the market you are interested in. Many times, tit for tat communication is not about picking words, but about answering or asking questions based on the other person's cognition. Hydraulic manifold manufacturer AAK is professional, so it is important to speak clearly and also speak to the customer's heart.

The hydraulic valve blocks designed and produced by AAK not only has high reliability and small pressure loss to ensure that there is no oil running between the channels, but also has compact structure, small occupied space, simple oil circuit and easy pipe layout, so as to ensure the high efficiency requirements of different actions of various actuator elements. The valve block can control the valve, which is easy to adjust and operate. AAK hydraulic valve block was designed and proofed successfully at one time within 1 month, which impressed the engineers of Samhydraulik company. The vast majority of hydraulic valve block manufacturers blindly proofed according to customer drawings, ignored working conditions, and did not understand the internal structure and working principle of hydraulic valve block. It is easy to cause hidden dangers in the hydraulic system, and the problem cannot be found. Justin left a message on AAK website (www.aakindustry.com) asking is the power insensitivity of the hydraulic system related to the hydraulic valve block? We replied that this is difficult to judge because it is a system problem that needs to be checked one by one. Justin emailed us the next day then we understood why he left such a message. Justin is from Samhydraulik in Italy. The power unit of a hydraulic system developed by his company needs a hydraulic valve block. Their engineers mentioned that the sensitivity of the power unit is the key and that all components need to cooperate closely. Justin thought that as long as the hydraulic valve block manufacturer strictly controlled the accuracy according to the drawings, it could be easily done. After the hydraulic valve block is finished, it is installed to test the hydraulic power unit. After the oil pump is started, the instantaneous pressure supply at the oil outlet of the power unit does not come up, and it just supply normal pressure after a few minutes. After checking each component one by one, it is suspected that there are hidden dangers in the hydraulic valve block. After detecting the hydraulic valve block, there is no problem in the oil passage and channel of the hydraulic valve block. Justin contacted the original hydraulic valve block manufacturer for analysis and solution. The manufacturer said that the hydraulic valve block was completely produced in accordance with the drawings of Samhydraulik company, and the accuracy was within the required range, and the reason for problem was unknown. Justin contacted several other hydraulic valve block manufacturers, they all said that they could match the drawings, but not sure about the problems of the hydraulic valve blocks. We asked Justin to tell us the working condition of the whole hydraulic system and the picture of the oil circuit running direction of the hydraulic valve blocks of the original manufacturer. AAK engineers have ideas after 3 aspects of comparative analysis. We told Justin that if your engineer determines that the problem lies in the hydraulic valve block, we will send you two samples of our hydraulic valve blocks to test your hydraulic system. Three days after receiving the samples, Justin informed that the instantaneous pressure supply at the oil outlet of the power unit was normal with AAK hydraulic valve blocks. Their engineers were surprised that AAK completed the design of the hydraulic valve block within 30 days and successfully proofed at one time. The problem of the hydraulic valve block lies in the high integration of the valve block design and the tortuous oil circuit, which will lead to high pressure loss and slow rise of system pressure. AAK engineers improved the design of the hydraulic valve block. The newly designed hydraulic valve block has no oil running between the channels, compact structure, small occupied space and optimized oil circuit piping, which not only has high reliability but also small pressure loss. AAK chief engineer has more than 20 years of technical experience. He is good at cross-sectional view, measurement and perspective of hydraulic valve block design system, multi angle observation of design process, hole connectivity, oil circuit optimization, and the escort of MDTools 3D solid design and virtual manufacturing software and high-precision CNC machining center imported from Switzerland. Many manufacturers do not know the problem of the hydraulic valve block. AAK can improve the design and make a successful proofing at one time within 30 days. I think this is the difference between AAK hydraulic valve block and its peers. AAK hydraulic valve block, not blindly based on drawings, but focused on the working principle, you are welcome to have a small try. https://www.aakindustry.com/info-detail/hy , draulic-valve-blocks-aak160

Mathias, a Dutch hydraulic customer, urgently needed to purchase a batch of hydraulic valve blocks matching the German brand from China at the end of last year. He asked more than 10 old hydraulic valve block manufacturers. They all said that the accuracy of this hydraulic valve block was too high for their technology and equipment. Mathias had a hunch that nine times out of ten, the order for this hydraulic valve block would fail, because he knew that most hydraulic valve manufacturers just have CNC machine tools. But his boss attached great importance to this customer and asked him to implement the hydraulic valve block sample within 30 days. Within a week, Mathias consulted nearly 20 hydraulic valve block factories online and offline, almost all of them just have CNC lathes. Only two of them said that they have Japanese high- precision CNC machine tools. They can try to make samples but are not 100% sure. Two weeks later, Mathias tested the hydraulic valve block samples from 2 factories, and there was still a parameter error of 10% - 13%. Mathias suggested the factory re-make samples, and both factories surrendered. Time has been wasted for 3 weeks. It's only 2 weeks from the deadline required by the boss. Mathias is anxious and has no direction. While chatting with old friend Andy, Mathias revealed his dilemma. Andy is a veteran in the hydraulic valve industry and has cooperated with AAK hydraulic valve for 5 consecutive years. Andy told Mathias that the accuracy of this hydraulic valve block requires not only high-precision machine tools, but also old operators who understand the equipment. Most hydraulic valve block manufacturers are difficult to meet these two requirements at the same time. He suggested Mathias try AAK, who likes to overtime difficulties on high-precision hydraulic valves, and most operators have more than 5 years of experience in operating imported equipment. The subject of Mathias's first email to AAK hydraulic valve was that I was introduced by Andy. He said that the accuracy of this hydraulic valve block can only be produced in AAK. Opening his hydraulic valve block drawing, AAK engineers have 90% confidence. I replied to him directly that if it goes well, we can send the hydraulic valve block samples before the Chinese New Year holiday. Jan 28th is our last working day before CNY and the last day to send samples. Our team was great to send the samples on Jan 28th. When we came back from the Spring Festival holiday, we received an email from Mathias. Their technical team tested the accuracy of AAK hydraulic valve blocks. Each parameter met the accuracy required by the drawing, and almost every parameter was 30% higher than that of other hydraulic valve manufacturers. AAK is also the only hydraulic valve block manufacturer that can match the German brand among all the hydraulic valve manufacturers he contacted. He can finally make a report to his boss. Next, the order confirmation process of hydraulic valve blocks is very smooth. Mathias understood why Andy is optimistic that AAK can achieve the accuracy of this hydraulic valve block. AAK introduced Demage five axis machining center as early as 2 years ago. The allowable rotation range is 115 ° (- 5 ° / + 110 °), which can carry out negative angle machining up to 20 ° and high- precision machining, which can not be achieved by many imported machine tools. At the same time, the torque can reach 1800Nm, the Y-axis stroke can be increased from 1250 to 1600mm, and the maximum speed of milling spindle can reach 8000r/min, while the maximum of conventional CNC can only reach about 5000r/min. As long as the operator is familiar with the performance of the equipment, the hydraulic valve block similar complicated to that of Mathias is successfully proofed at one time. AAK hydraulic valve block is praised by Mathias that it is the only one that can match the German brand. Give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak156

Some customers choose to transport hydraulic directional control valves exported to the Russian market by train, which may cause collisions due to multiple turnover shipments in inland China. Anek from Russia has encountered a problem with China. In the second half of last year, Anek wanted to purchase a batch of hydraulic directional control valves, which is equivalent to the HydraForce standard part LS08-30. There are no less than 5 hydraulic valve manufacturers in Ningbo China that have the program for this hydraulic directional control valve. Although AAK received Anek's inquiry, he chose the hydraulic directional control valve manufacturer with lowest price to place an order. The order was finished in less than 1 month, but it took nearly 2 months on the road from Ningbo to Moscow. After receiving the shipment, Anek was dumbfounded. The outer box was cracked and deformed, and some hydraulic directional control valves had fallen out of the outer box. What's even more frustrating was that due to the collision of the hydraulic directional control valves to each other, some threads had also been damaged. The manufacturer for these hydraulic directional control valves indicated that he cannot bear responsibility for any damage caused during transportation. Anek sent an email asking me to produce 160 pcs of LS08-30 hydraulic directional control valves as soon as possible, and ship them by air for emergency assistance. After communication, it was learned that he encountered packaging problems with the original hydraulic valve manufacturer. I jokingly said that you have been purchasing from AAK for 4 years and have never encountered any problems with packaging, right? He just sent me a “like” expression and an “awkward” expression. In the manufacturing of hydraulic directional control valves, small details often determine the customer's experience. AAK checks each hydraulic directional control valve separately before entering the packaging workshop for packaging. Firstly, put the hydraulic directional control valve into a bubble bag, it just likes to wear a piece of underwear to prevent scratches. Then put it into a 3ply hard corrugated box with the fitted size, which not only provides an additional layer of protection but also fixes the hydraulic directional control valve in place. Then put 24 pcs, or 36 pcs, or 48 pcs into a 5ply corrugated cardboard boxes with fragile and easy to handle markings, and then secured with “#" shaped packaging tape. For those exceeding 10KGS, wooden boxes will be used for protection. 1 reminder, 4 protections, as long as there is no malicious human damage, the hydraulic directional control valves are 100% collision free. But most hydraulic valve manufacturers in China have no experience in dealing with exports, and the root cause is that they have become accustomed to the domestic market in China. Using the Cognitive inertia of domestic sales to export, it harms customers and also themselves. AAK hydraulic directional control valve, 1 reminder, 4 protections, 100% collision free, you can also give it a try!

Henry is a purchaser of a hydraulic power unit manufacturer in the United States. He almost lost his job when he purchased the hydraulic pressure relief valves in the first time after just joining the company. AAK high-precision hydraulic pressure relief valves saved the job for him. Last October, one of their African customers customized a batch of hydraulic power unit equipment for use in African mining bases. The requirements of the equipment for the hydraulic pressure relief valves used are that there is no abnormality within 1 year. Henry contacted more than 10 hydraulic pressure relief valve manufacturers and screened 4 samples from each of 4 factories. A month later, the engineering department debugged these hydraulic pressure relief valves. Almost all hydraulic pressure relief valves from every factory have unstable hydraulic system pressure, but only the proportion is different. At first, the engineer thought it was due to the installation of hydraulic pressure relief valves or the problem of oil quality. After several commissioning, it was found that the outlet pressure of hydraulic pressure relief valves was almost equal to the inlet pressure. After disassembling the hydraulic pressure relief valves, it is found that the geometric tolerance is out of tolerance due to the accuracy of the main valve spool and valve hole. After knowing this, the boss thought that Henry had a problem on the communication with the hydraulic pressure relief valve manufacturers and asked him to solve the purchasing of the hydraulic pressure relief valves with the manufacturers within 4 weeks. Henry has made two rounds of screening for hydraulic pressure relief valve manufacturers and emphasized the working conditions, but still no one can achieve that every hydraulic pressure relief valve has no problem. He felt that he was cheated. The water in the hydraulic pressure relief valve industry was too deep. Henry found AAK hydraulic valve on Google and left a message on our website: Can AAK get the geometric tolerance of each hydraulic pressure relief valve consistent? After several rounds of e-mail communications, we learned about what happened when he purchased hydraulic pressure relief valves for the first time. We can only comfort him that he was misled by hydraulic pressure relief valve manufacturers due to lack of experience. He can test the samples of AAK hydraulic pressure relief valves. Three weeks later, AAK sent Henry 5 samples of hydraulic pressure relief valves. Their engineer tested each sample 3 times, and the hydraulic power unit equipment was normal. The boss praised his emergency ability. Now Henry doesn't have to worry about losing his job. We told Henry that according to the working conditions and drawings of this hydraulic pressure relief valve, the accuracy of each hydraulic pressure relief valve is required to meet the standard and be stable, which needs to meet two points: one is the selection of materials, the other is the control of machining accuracy and the error correction of accuracy in machining, which is the key. AAK use the GILDEMEISTER turn milling compound machining center imported from Germany. During the machining process of various parts of the valve body, the central encoder can be used to measure the position and compensate the errors caused by tool wear. The worktable adopts the static pressure guide rail with pure static pressure load, which has strong bearing capacity. At the same time, it has the c-axis position detection technology with double reading heads that is not available in general equipment. The positioning accuracy of c-axis can reach 5 arc seconds, while at present, most hydraulic pressure relief valve manufacturers do not have this kind of equipment. AAK hydraulic pressure relief valves are produced by high-precision advanced equipment. Welcome to have a small try! https://www.aakindustry.com/

Devante is from a hydraulic equipment company in Spain. He has been purchasing for 8 years and cooperating with AAK for 3 years. In June last year, a batch of hydraulic cylinders of their company were complained of telescoping jitter. During after- sales service, it was judged that the hydraulic cartridge relief valve of the hydraulic system was abnormal. After disassembly, it was found that the spring elasticity in the valve body was out of function. The manufacturer of the hydraulic cartridge relief valve thought that the high working frequency of oil cylinder caused spring failure. It could be replaced for free for good cooperation, but the complaints were increasing later. The boss was not satisfied with the hydraulic cartridge relief valves purchased by Devante this time, and Devante had a great pressure. At the beginning of last year, their engineer required the manufacturing quality of the hydraulic cartridge relief valve for the hydraulic cylinder they developed, to benchmark HydraForce. Devante believed that the function of this hydraulic cartridge relief valve is relatively conventional, so he chose a hydraulic cartridge relief valve manufacturer with competitive price. Unexpectedly, the service life would be exhausted in less than 6 months. Devante regreted choosing the wrong hydraulic cartridge valve manufacturer. He redefined the quality of this hydraulic cartridge relief valve: no repair within 1 year, and the service life of the built-in spring shall not be less than 18 months. In 1 week, only 2 hydraulic relief valve manufacturers accepted to try the samples, and AAK was one of them. 1 month later, the samples of hydraulic cartridge relief valves from 2 manufacturers were installed on different hydraulic cylinders, to PK directly. Last week, Devante emailed that the hydraulic cartridge relief valves of the cylinders had been replaced. In 1 year, there was no customer complaint about the hydraulic cylinder installed with AAK hydraulic cartridge relief valves, while the other one was just stuck in 1 year. Their engineer tested the built- in spring of AAK. After 1 year of high frequency work, its fatigue resistance was still like a new material. I replied that the difficulty of this hydraulic cartridge relief valve is just the fatigue resistance of the spring. As long as this is solved, you will have no worries about using it for 18 months. For the spring of this hydraulic cartridge relief valve, AAK uses German UP6 spring steel, which is optimized according to 60Si2Mn alloy steel. Its strength and elasticity can be fully suitable in military equipment. The fatigue resistance of the spring is more than 3 times that of other carbon steel springs, which is the core reason why the other manufacturer’s has been out of use in 1 year, while AAK's is worry free in 18 months. Although the cost of this spring is more than 2 times higher than that of other materials, even if the cost of the material is 3 to 5 times higher, the best one should be chosen. Things that are not good enough cannot be used by AAK, let alone given to users. AAK hydraulic cartridge relief valve, worry free in 18 months, welcome you to try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak393

Andreus is from a hydraulic equipment company in Chile. He has been in purchasing smoothly for 2 years. At the beginning of the year, their company received an inquiry for a batch of personalized excavators, and customer needed prototypes. The hydraulic cartridge counterbalance valve in the hydraulic system is the key. Their engineer asked Andreus to purchase the standard parts of SUN hydraulic cartridge counterbalance valves, but the parameters did not match, and SUN was unwilling to customize. They had to work with a hydraulic cartridge valve manufacturer who had cooperated with them for 4 years to make samples. But the test run was not smooth. When the load pressure was applied, the opening of the main valve spool of the hydraulic cartridge counterbalance valve would change, affecting the flow and causing the main engine to shake. The hydraulic cartridge counterbalance valve manufacturer had no solution but to give up. Andreus contacted more than 10 other hydraulic cartridge valve manufacturers, but still no result after 1 week. The engineer was impatient, and Andreus was worried. Andreus browsed AAK website on Google and clicked the article and product introduction about hydraulic cartridge counterbalance valves for many times. He left us a message: How to keep the hydraulic cartridge counterbalance valve free from load interference and stable flow? I replied: There are many reasons for the problem, which should be analyzed in details. According to the video of abnormal equipment sent by him, as well as the production drawings of the hydraulic cartridge counterbalance valve, AAK engineers judged that the structure should be optimized and AAK is 90% confident to solve the problem. Andreus saw the hope and asked for AAK samples. After 50 days, AAK sent 20 hydraulic cartridge counterbalance valve samples. 1 month later, Andreus informed that after the excavator was equipped with AAK hydraulic cartridge counterbalance valve, the equipment was running stably and the prototype had been sent to the customer. AAK hydraulic cartridge counterbalance valve can resist the pressure fluctuation when the load drops, and the flow is stable. We have made 3 structural optimizations. The hydraulic cartridge counterbalance valve is composed of 5 parts: valve body, valve seat, main valve spool, pilot valve spool and pilot mechanism. 1. The valve seat of the hydraulic cartridge counterbalance valve is connected with the valve body to form a connected first channel, and the extended end of the valve seat butts against the pilot mechanism to form a second channel. 2. The main valve spool of the hydraulic cartridge counterbalance valve is provided with a throttling groove, the other end is connected with the inner cavity of the main valve spool, and the pilot drive part is used to drive the pilot valve spool. 3. One end of the pilot valve spool of the hydraulic cartridge counterbalance valve is slidably arranged in the inner chamber of the main valve spool, and the other end is connected with the pilot mechanism. The pilot valve spool is also provided with a throttling groove, an axial pilot valve spool chamber and an orifice. The optimized balance structure of the hydraulic cartridge counterbalance valve, which connects the pilot valve spool and the inner chamber of the main valve spool, enables the oil pressure through the 2 channel ports to form a balance on the pilot valve spool, and the opening of the main valve spool under the force of the pilot mechanism can not be affected by the load pressure fluctuation. AAK hydraulic cartridge counterbalance valve, no load interference, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-valves-aak456

Chapin is from Canada and has purchased hydraulic cartridge valves in Ningbo for 5 years. At the beginning of this year, their hydraulic cylinder needed hydraulic directional control cartridge valve. He found a hydraulic directional control cartridge valve manufacturer in Ningbo to test the sample, but it was not successful. When the external load of the oil cylinder suddenly changes, the response of the hydraulic direction control cartridge valve is slow, and the shunt accuracy cannot keep up with it, which is not synchronized with the execution of the oil cylinder. According to the feedback from the original manufacturer of the hydraulic directional control cartridge valve, this is the standard model of HydraForce hydraulic directional control cartridge valve. Now the function does not match, so he can only replace it with other model of HydraForce standard parts. Chapin was a little confused. Chapin contacted AAK under the introduction of his friends, and told us the dilemma of the hydraulic directional control cartridge valve sample at present, and asked whether AAK could improve the function of the original hydraulic directional control cartridge valve to match the cylinder execution synchronization? 2 days later, AAK's plan was ready. Chapin paid the development fee the next day and asked for AAK samples. After 40 days, AAK sent the samples of hydraulic directional control cartridge valves. Yesterday, Chapin informed us by email that the test run was successful. After replacing with the AAK hydraulic directional control cartridge valve, the cylinder execution was synchronized and the stability was improved. The prototype has been delivered to the customer. AAK hydraulic directional control cartridge valve has fast response, high shunt accuracy and stability. These 3 advantages are attributed to the optimization of 3 structures based on the original hydraulic directional control cartridge valve. 1. On the main valve sleeve wall of the hydraulic directional control cartridge valve, there are external main oil ports, 2 external load oil ports, locating pins, floating steel balls, and grooves corresponding to the through-hole. The floating steel balls float between the bottom of the locating pins and the grooves. This ensures that the internal load oil port and the external load oil port are always connected, which can realize the static two-way stroke correction of the two load cylinders, and remove the obstacles for synchronization. 2. The spool valve of the hydraulic direction control cartridge valve is sleeved with an inner main oil port and an inner load oil port, and the throttling channel connected with the inner main oil port is on the valve spool. The throttling channel has a fixed orifice and a variable orifice which are connected with each other. The fixed orifice is connected with the inner main oil port. The spool slides back and forth in the spool sleeve to adjust the flow area between the throttle passage and the internal load port. 3. There is also a dynamic variable damping device between the spool and the spool sleeve. When the load suddenly changes, the dynamic variable damping device, under the effect of hydraulic pressure difference, pushes the spool to move, and increases the damping force of the spool when it slides back and forth in the spool sleeve to change the dynamic characteristics of the spool when it slides back and forth in the spool sleeve, reducing the dynamic flow error, and improving the accuracy of diversion. AAK hydraulic directional control cartridge valve, has 1 more function than HydraForce and 3 advantages.

Bill is a purchaser of Manitowoc company in the United States. Two years ago, AAK received an inquiry about hydraulic counterbalance valves from him, and there were few contacts later. Unexpectedly, two years later, we received an email from him consulting about the problems of the hydraulic counterbalance valves. After communication, we learned that a batch of hydraulic counterbalance valves he purchased elsewhere had problems and almost got into a big trouble. Last summer, a crane shipped by their company, the crane winch system lost control during construction and the hook slipped off. Fortunately, there was no one under the hook at that time, otherwise there would be great trouble. According to the analysis of the field engineer, it is considered that the hydraulic counterbalance valve used in the crane winch system is abnormal. After disassembling the hydraulic counterbalance valve, it is found that there is a deviation in the concentricity between the valve spool and the valve seat. The valve spool is affected by large eccentric hydraulic force, so that the hydraulic counterbalance valve lost its function of balance and the hook slipped off. After knowing the reason, Bill contacted the original hydraulic counterbalance valve supplier. The supplier replied that the hydraulic counterbalance valves were indeed within the warranty period, he can replace the abnormal hydraulic counterbalance valves with a new ones, but can not guarantee that each hydraulic counterbalance valve had the same concentricity and could be used for more than 1 year. Bill was worried about the stability of the new hydraulic counterbalance valves. He didn't want to have big trouble and had to find a new hydraulic counterbalance valve manufacturer. In crane hydraulic system, the performance of hydraulic counterbalance valve is the cornerstone of winch system, and the consistency of hydraulic counterbalance valve concentricity is the key. Bill also asked other hydraulic counterbalance valve manufacturers. No factory guarantees that the concentricity of the hydraulic counterbalance valve can be still consistent after 1 year of use. Bill wants to know how about the concentricity of AAK hydraulic counterbalance valves after being used for 1 year. We told Bill that perhaps having a try is the best answer. He can detect the concentricity of AAK hydraulic counterbalance valves in an all-round way. After 15 days, we sent 4 samples of hydraulic counterbalance valves according to his drawings. Seven days later, Bill informed us that the concentricity test data of AAK hydraulic counterbalance valves were indeed more comprehensive than that of his original manufacturer. How to ensure that the concentricity of AAK hydraulic counterbalance valves is still consistent after 1 year of use? For some manufacturers, when processing the components of hydraulic counterbalance valves, there are discrepancies between the specification parameters and design, the standard of normal distribution cannot be reached, there are certain differences in between the structure of components and the concentricity of grooves, which is difficult to detect. AAK has Mahr cylindricity instrument imported from Germany. Through EasyForm software, it can measure each part accurately and quickly, and obtain the measurement results. With the help of computer, the work piece can be quickly adjusted and aligned to improve the measurement efficiency, ensuring the concentricity of each hydraulic counterbalance valve is 100% consistent to reduce wear. More than half a year later, Bill sent an email saying that another two hydraulic valve manufacturers that he recognized, also provided samples of hydraulic counterbalance valves with AAK together last time. All the hydraulic counterbalance valves were retested after 6 months of use. It was found that the concentricity of the hydraulic counterbalance valves from another two manufacturers changed compared with the data before use, but the concentricity of AAK hydraulic counterbalance valves did not change. The boss asked him to list AAK as the most trusted supplier for their hydraulic counterbalance valves. AAK hydraulic counterbalance valves, are sophisticatedly inspected, can be used without no trouble.

Yaroslav from Russia always likes to find new hydraulic cartridge valve manufacturers for trial orders. When encountering problems, he also asks these hydraulic cartridge valve manufacturers to come to me for help and solutions. Considering Yaroslav's 5-year experience of purchasing from AAK hydraulic cartridge valve manufacturer emotionally, I will truthfully provide assistance to these hydraulic cartridge valve manufacturers in the situation of without wasting my emotions. Yesterday, Yaroslav recommended my WeChat account to the owner of a hydraulic cartridge valve manufacturer in Ningbo China, saying that this manufacturer would like to consult me about hydraulic cartridge valve issues. I estimated he has encountered difficulties on the order placed with this hydraulic cartridge valve manufacturer, and approved this owner’s WeChat friend connection request. The communication is as follows: “Are you Kevin? Yaroslav is my client and he asked me to come to you. I would like to discuss some issues with hydraulic cartridge valves with you.". You are asking for help from someone, but the way is so impolite. What is a discussion? My emotions have also come up, so I replied: “I'm Kevin, but I don't understand hydraulic cartridge valves and I can't discuss it with you. Besides, I'm busy right now. ". The other person replied, still tactlessly and condescendingly. “Aren't you a manufacturer of hydraulic cartridge valves? Why don't you understand?” “I just have a rough understanding about hydraulic cartridge valves, and can only echo what the books say. I haven't reached the level of discussing with others yet! ". He still couldn't see that I was politely refusing, and started leaving messages on his own. "I have been a manufacturer of hydraulic cartridge valves for 5 years, and I don't like to produce trial orders, but there are always clients who ask me to produce trial orders, and they are also very picky about some small problems, other manufacturers of hydraulic cartridge valves are unwilling to do..." etc. He said a lot. I only replied with one sentence and deleted the WeChat account of this hydraulic cartridge valve manufacturer. "You are talking about the trial order of hydraulic cartridge valves. Although I am also a manufacturer of hydraulic cartridge valves, my trial order team is as old as you. I have some experience about how to guide a trial order team well, but regarding how to guide a 5-year hydraulic cartridge valve manufacturer, I am a bit rusty after a long time!". At the same time, I also replied to Yaroslav, “This hydraulic cartridge valve manufacturer is very awesome, and my ability cannot help him.” As the saying goes, “Fish begins to stink at the head.”. How can the entire team be good if the owner of a hydraulic cartridge valve manufacturer has such a rude virtue? I would like to provide a suggestion for young hydraulic cartridge valve manufacturers: first learn to be a person, and then think about how to manage the hydraulic cartridge valve team.
