This week, we launched a hydraulic cartridge logic element benchmark SUN DKFS- XHN. This hydraulic logic element is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position. Most of hydraulic cartridge valve manufacturers in Ningbo China do not have this model. One of our customers in Brazil checked with 5 hydraulic valve manufacturers in 2 months, but none of them have this logic element. He was very happily to finally find it at AAK. But for it is his first time to do business with AAK, he ordered only 5pcs first last June as the trial order. Today, we received his regular order of 1,000 pcs for this SUN model DKFS-XHN Normally closed, balanced poppet, pilot-to-open logic element. It is said that AAK E-DKFS-XHN has passed the testing in the past year, its quality, function and performance is equivalent to SUN DKFS-XHN. AAK hydraulic logic element 2 major advantages: 1. Manufacturing quality, function and performance benchmark SUN. 2. But the price is less than 70% of SUN.

Cuenca is a senior purchaser of AGRIA company in Spain. The boss is very satisfied with his purchasing work. Two years ago, AGRIA company developed a hydraulic equipment, and there were complaints after sales for more than half a year. The main problem was that the starting force of the hydraulic system would be insufficient, which was caused by the increase of internal leakage of the hydraulic check valves in the equipment. After Cuenca contacted the original hydraulic check valve manufacturer, the manufacturer said that some hydraulic check valves may have deviation during assembly, and he was willing to replace the hydraulic check valves with large leakage with new ones. Cuenca thought it was completely solved after replacement, but what surprised him was that less than a year after the new hydraulic check valve was replaced, the same problem occurred again. The boss was very disappointed with his purchase of hydraulic check valves this time. The manufacturer of the original hydraulic check valves still said that except for replacing the hydraulic check valves, there is no other way. Cuenca began to worry that if the same problem happened a third time, it would be too shameless. To be safe, he began to look for a new supplier of hydraulic check valves and began to test samples. At the same time, he also wanted to know why the hydraulic check valves produced by the original manufacturer leaked. In this way, Cuenca contacted AAK hydraulic valve. After several rounds of communication with Cuenca, we learned the story between him and the original manufacturer of hydraulic check valves, and suggested him to send us the hydraulic check valves with problem and provide us the drawings of hydraulic check valves at the same time. AAK engineer disassembled the hydraulic check valves of the original manufacturer and found that there were wear marks on the sealing line on the surface of the poppet valve. When the pressure oil reversely enters the hydraulic check valve, the cone cannot strictly seal the oil and cause leakage, and some oil flows out of the oil inlet. After receiving AAK's analysis, Cuenca asked us to make 4 samples of hydraulic check valves according to his drawings. Our engineers designed a new hydraulic check valve according to the service frequency and working conditions of the equipment, replacing the cone valve with the ball valve. The cone valve is prone to fatigue creep deformation and wear after working for a long time, resulting in a gap between the valve sleeve and the cone, resulting in leakage. The outer circle of the ball valve can contact the inner taper ring line, and the connecting hole can be closed to reduce the leakage caused by wear. Cuenca was surprised that AAK dared to take the initiative to modify the drawings of their hydraulic check valves, and expected to see the sample performance of AAK hydraulic check valves. Two months later, AAK sent samples of the newly designed hydraulic check valves. A year later, Cuenca said that the hydraulic equipment equipped with AAK hydraulic check valves had no complaints about startup. He was glad that the original hydraulic check valve manufacturer replaced it again and again, which could only guarantee the service for half a year, but AAK solved the problem one time. In only 2 months, AAK helped solve the problem of leakage in the hydraulic check valves that plagued Cuenca for nearly 2 years. Cuenca would rather give up the original supplier who has cooperated for many years than choose AAK hydraulic check valves. AAK hydraulic check valve, valve spool design is unique and different, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak165

Bauer is from Brazil and has purchased hydraulic cartridge valves from AAK 6 times. In the second half of last year, they developed a drilling equipment. The hydraulic pressure control cartridge valve used on the equipment was sampled from a local hydraulic cartridge valve manufacturer in Brazil. The equipment commissioning was not smooth, and the impact of the drilling rig during startup and shutdown is large, which is not acceptable to the customer. The root cause is the unstable unloading of the hydraulic pressure control cartridge valve after overloading. The original hydraulic pressure control cartridge valve manufacturer stated that it was manufactured according to the drawings and its accuracy reached the standard. Bauer was helpless. Bauer contacted me and emailed me asking if AAK can produce a hydraulic pressure control cartridge valve with stable unloading after overloading, especially during equipment startup and shutdown. After communication, I learned the dilemma that Bauer encountered with the original hydraulic cartridge valve manufacturer. After discussion, AAK engineers gave the solution to the hydraulic pressure control cartridge valve, and Bauer asked AAK to make samples. After 45 days, AAK sent 10 hydraulic pressure control cartridge valves. 1 month later, Bauer informed us by email that AAK hydraulic pressure control cartridge valve was installed on the drilling rig, with minimal impact during startup and shutdown. Their equipment prototype had been delivered to the customer, and he was confident that the customer would place a batch order. AAK hydraulic pressure control cartridge valve not only achieves stable unloading after overloading, but also reduces impact. These are 2 advantages compared with the Brazilian hydraulic cartridge valve manufacturer. AAK hydraulic pressure control cartridge valve can adjust the annular orifice, the first and second orifices to achieve buffering and smooth operation of the equipment under various working conditions. AAK optimized the hydraulic pressure control cartridge valve in the following ways: 1. The hydraulic pressure control cartridge valve sleeve is provided with an oil return port and an oil discharge port, and a valve seat with a through hole is fixed. The valve spool is covered with a spring, and there is an oil passage inside the valve spool. The lower end of the valve spool is a tapered end. 2. The upper end of the valve spool extends into the valve spool sleeve, which is housed in the adjusting seat with a screw plug inside and a lock nut outside. Threaded connections are used between the lock nut and the adjusting seat, between the adjusting seat and the valve sleeve, and between the screw plug and the adjusting seat. 3. The screw plug cooperates with the valve spool sleeve to form a second oil chamber. The valve spool sleeve has two throttle holes and an annular throttle hole. The valve spool cooperates with the valve spool sleeve to form a first oil chamber. The lower end of the valve spool has an outer circumferential surface and a column that matches the inner wall of the valve sleeve. AAK hydraulic pressure control cartridge valve has 2 advantages over Brazilian hydraulic cartridge valve manufacturer. You can also give it a try! https://www.aakindustry.com/info-detai , l/pressure-control-cartridge-valves- aak533

Andy is our old hydraulic valve customer in the United States. The hydraulic cartridge valves he purchased from AAK in previous years always has a standard of machining surface roughness around 0.8μm. In February last year, Andy sent an email to inform us that in the future, the machining surface accuracy of their hydraulic cartridge valves will be improved to within 0.3μm. AAK engineers believe that based on the current equipment system, it is very difficult to improve the machining surface accuracy of hydraulic cartridge valves to 0.3μm. It is also very difficult to find such a hydraulic cartridge valve manufacturer in Ningbo. I know that AAK has only two options, either give up the business of his hydraulic cartridge valves or accept his accuracy standard. This is the first time I have faced the choice of "standing in line" since I joined the hydraulic valve industry. The cooperation with Andy has always been trustworthy, pleasant and efficient. AAK doesn't want to give up such customers. After two rounds of communication internally, AAK technical team has not reached a consensus. I have to call my retired master and hope to hear his opinions. My master told me that this is a rare opportunity to catch up with and surpass the accuracy of international hydraulic cartridge valves. The roughness of the working surface under 0.3μm is rare in China, but some European hydraulic cartridge valve manufacturers have this strength. AAK must first start with the equipment, and then select the most experienced operators from the factory for special aircraft training, so as to have the opportunity to compete with those top European hydraulic cartridge valve manufacturers. American HARDINGE precision CNC lathe is worthy of a try. At present, none of the domestic hydraulic cartridge valve manufacturers have this equipment. After contacting the equipment manufacturer, AAK technical team took the hydraulic cartridge valves produced for Andy before to the equipment factory, and asked the engineer of the equipment manufacturer to go directly to the machine for proofing. A week later, we sent the hydraulic cartridge valve samples to Andy and asked them to test the accuracy parameters. Two weeks later, Andy informed that the previous hydraulic cartridge valve accuracy test was completed twice. This time, AAK hydraulic cartridge valve was tested 4 times, and the accuracy fully met the standard. At the same time, he told me that after receiving the accuracy improvement notice, the other 3 domestic hydraulic cartridge valve manufacturers directly gave up, and only AAK dared to test the sample and succeeded in one test. He was very surprised. The machine tool to be introduced by AAK has advantages in accuracy. The parameters of the machine tool: spindle speed up to 6000r/ min, spindle radial run out ≤ 0.0008mm, positioning accuracy (X/Z) ≤ 0.005mm/0.008mm, repeated positioning accuracy (X/Z) ≤ 0.003mm/0.005mm, and machining surface roughness Ra ≤ 0.3μm. Turning roundness ≤ 0.4μm. Turning cylindricity ≤ 0.1μm. The spindle is a spring collet to clamp the workpiece, with large clamping area and stable processing. It is equipped with FANUC21i-T numerical control system with high precision. Now this HARDINGE machine tool is almost the special equipment for the orders from Andy. The order volume that Andy awarded to AAK has also increased by nearly 60%. He said that AAK hydraulic cartridge valve has surpassed many European factories in terms of precision.\ AAK hydraulic cartridge valves, with precision surpassing that of Europe, you are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-cartridge-valves-aak164

AAK uses the DMG five axis machining center imported from Germany, which improves the stability and accuracy by 30%. Less than 5% of the hydraulic valve block manufacturers in the domestic industry are equipped with this set of equipment. After suffering losses elsewhere, an American customer went back to AAK after 45 days to place the order for hydraulic valve blocks. Last December, I received an inquiry from American customer Joshua about a hydraulic valve block. At that time, I was a little surprised to see the accuracy requirements of the hydraulic valve block. The accuracy was 5% higher than that of HydraForce series. This was not a small challenge, but I was still confident. The next day, I sent quotation to Joshua directly. Joshua then said that it was 12% higher compared with other hydraulic valve block manufacturers, he could not place an order with AAK. After 45 days, Joshua asked us whether the last quotation of hydraulic valve block was still valid. If the original price is maintained, he will place the order for the hydraulic valve block. For the sincerity of cooperation, Joshua also frankly told why he moved the hydraulic valve block order to AAK. The original hydraulic valve block manufacturer made samples for two times, and the parameters of each hydraulic valve block were not very stable. Some hydraulic valve block sample had very good accuracy, while others were very poor, which wasted 3 weeks of time. Joshua also checked with other manufacturers. All of them are not confident to achieve the accuracy that is 5% higher than that of HydraForce series. Another 2 weeks were wasted again. The customer was very angry that the order has been placed for 5 weeks, but the sample of the hydraulic valve block still could not be approved. Joshua felt that only AAK can make the sample successfully at one time. Even if it is 12% more expensive, it is acceptable. Aware of Joshua's dilemma, we specially spare a high-precision DMG five axis machining center lathe to arrange the proofing of this hydraulic valve block. A week later, AAK sent the hydraulic valve block samples. After 10 days, there was still no feedback from Joshua about the hydraulic valve block samples. We asked Joshua to know that he was also waiting nervously. Until Joshua's email last week, we know that his customer was very surprised that the accuracy of this hydraulic valve block sample not only exceeded 5% that of the HydraForce series, but the parameter stability of AAK hydraulic valve block was also more than 30% higher than that last time. Frankly, we were not surprised by this data, because more than one customer was surprised by the accuracy parameters of AAK hydraulic valve blocks. The reason why the accuracy of AAK hydraulic valve block exceeds 5% of HydraForce series is that it firstly benefits from the continuous updating of the equipment. When the vast majority of hydraulic valve block manufacturers update from CNC lathe to domestic Mazak machine tool, AAK introduces DMG five axis machining center produced in Germany. The domestic Mazak machine tools have weak rigidity, poor stability and low precision after long-term processing. The lathe of DMG five axis machining center is equipped with transverse sliding seat of stiffened cast iron column, which provides the machine with high precision and high rigidity. It adopts the latest numerical control technology DMGEROline ® control panel, 19" display and 3D software, and guarantee the maximum working speed, accuracy and reliability.

A top 3 hydraulic manifold importer in the United States, has been purchasing from a hydraulic manifold manufacturer in Ningbo China for 3 years. I met their procurement director Steven 2 years ago, but he did not know me. Last October, I learned that Steven had come to Ningbo, and I wanted to get to know him and introduce hydraulic manifold manufacturer AAK to him. I waited in the lobby of the hotel for over 3 hours, and when I saw Steven returning, I politely greeted him and presented my business card. I also briefly introduced the hydraulic manifold manufacturer AAK, and Steven replied gentlemanly, "I have your business card, so you can go back early.". At this point, if I say goodbye, it's estimated that the business card of hydraulic manifold manufacturer AAK will be in the trash can. On the road of business, do people, from strangers to acquaintances, essentially make use of each other? When you are valuable in front of others, some things are easy to talk about. I answered this way at the time: Thank you Steven for giving me a few minutes. I will say goodbye soon, but you need to keep this business card because it is very valuable to you. Steven shook the business card and asked with a smile, "What value does it have for me? You can talk about it.” I told him that there are 3 values. I know you have been purchasing from that hydraulic manifold manufacturer in Ningbo China for 3 years, and this hydraulic manifold manufacturer is also good. From the selection of suppliers, it can be seen that you are professional, which is why I came to visit you. I don't say that hydraulic manifold manufacturer AAK is better than your supplier, but at least not worse than him. For you, if there are any issues with the original supplier, hydraulic manifold manufacturer AAK is your best alternative option, so the first value that hydraulic manifold manufacturer AAK brings to you is safety. In the hydraulic manifold industry, hydraulic manifold manufacturer AAK is synchronized with your supplier. If you only cooperate with this one company, then there is a lot of information in this industry, and perhaps you only know half of it. With hydraulic manifold manufacturer AAK as a supplement, you are basically familiar with the information in this industry. If your boss wants to ask, how do you think about the development of this industry and how to adjust your procurement ideas in the future, you can have more comprehensive information. So the second value brought by hydraulic manifold manufacturer AAK is information value. The third value, if your supplier knows that hydraulic manifold manufacturer AAK is contacting you and he is also a bit nervous, perhaps he will treat you better, so the third value brought by hydraulic manifold manufacturer AAK is chip value. Finally, I told Steven that I know it's a bit difficult to discuss cooperation with you now. I only have one small request. Once you have the opportunity, can you give hydraulic manifold manufacturer AAK a try to see our manufacturing quality and my abilities? Is this a small request acceptable to you? Steven looked at the business card of hydraulic manifold manufacturer AAK again and said, "Okay, I will keep this business card for now.". At the same time, he also gave me his business card. Yesterday, I received an inquiry from Steven for a hydraulic manifold, and I have been waiting for him for 14 months. After communication, it was learned that the original supplier stumbled on this hydraulic manifold, which put Steven in a very passive position. I know and believe that the opportunity has come for hydraulic manifold manufacturer AAK.

Dimon is a new buyer of a hydraulic equipment manufacturing company in the United States. In the second half of last year, he purchased 100 hydraulic needle valves from an old supplier. After receiving the goods, the hydraulic needle valves were installed on the equipment. A few months later, some users complained that the pressure supply of some equipment was insufficient. Their technicians judged that the radial jamming of the valve spool of the hydraulic needle valve resulted in no flow regulation, which would lead to the failure of the power unit. The hydraulic needle valves need to be replaced with new ones as soon as possible to eliminate user complaints. His boss is not very satisfied that problem happened on even such a small number purchasing of hydraulic needle valves. Dimon is confused why the hydraulic needle valve supplier who had cooperated for 2 years would have such quality problems. He sent some problematic hydraulic needle valves back to the factory. The manufacturer replied that the accuracy of these hydraulic needle valves met the standard, but a small deviation in the size of the valve spool was caused by the deviation of the assembler. At that time, several valves were assembled at the same time in the assembly workshop, and a few deviations were difficult to avoid. Dimon realized that even the original manufacturer replaced the hydraulic needle valves with new ones, it still can not solve the problem of the radial jamming of the valve spool for 100%. He was afraid that if there were more user complaints, could he keep his job during the probation period? Dimon decided to find a new supplier of hydraulic needle valves. He left a message on our website: Can you solve the problem of radial jamming of the valve spool of hydraulic needle valve? At first, it was hard to answer this question. After several rounds of communication, we learned the story of his purchase of these 100 hydraulic needle valves. After reviewing the working conditions and drawings of hydraulic needle valve from Dimon, as well as the pictures of hydraulic needle valves from the original supplier, AAK suggested him trying samples directly. 20 days later, AAK sent 10 samples of hydraulic needle valves made per his requirements. Two months later, Dimon sent an email to us saying that he selected 5 factories from more than 20 hydraulic needle valve manufacturers to make samples. Only the samples from AAK and another factory did not have the problem of radial jamming of valve spool during the test. Their engineers suggested that AAK should be selected to replace the 100 hydraulic needle valves with potential quality problems, because the parameters of AAK hydraulic needle valve are the most stable. The boss knew that he dared to develop new suppliers and solved the hidden quality problems, although the probation period is not over yet, Dimon was approved to become a regular in advance. He told us this story privately. To do this hydraulic needle valve well, it needs not only high-precision equipment, but also need to avoid personal assembly errors. AAK has technical workers with more than 10 years of operation and production experience, combined with advanced high-precision honing machines, CNC machine tools and other production equipment, as well as advanced three coordinate instrument, cylindricity instrument, profilometer and other testing equipment. The most important thing is that AAK has specially assigned personnel to control the assembly process of hydraulic needle valves, so as to avoid partial mixture wrong assembly caused by cross assembly by multiple people, especially in the assembly process of similar valve bodies. Many factories arrange cross assembly in order to save personnel and improve efficiency, resulting in wrong assembly of accessories. This assembly process of AAK hydraulic needle valves is unique in the industry. Maybe there is no second factory in Ningbo, the hometown of hydraulic valves to do this like us. AAK hydraulic needle valves, no radial jamming of valve spool problem, welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak162

Advanced Ground Support Systems Ltd (BL), the hydraulic vehicle TOP 3 in Russia, such as Fenox. There are some in niche markets that are very particular about quality, such as Adimkoza. There are also cartridge valve wholesalers from Türkiye, Mexico and so on. The hydraulic cartridge valve manufacturer AAK, has exported hydraulic cartridge valves to 23 countries. The hydraulic cartridge valve manufacturer AAK, not only serves old customers well, but also continuously attracts new customers. Any old customer has evolved from a new one. I have found that any new customer likes to ask 3 questions the most, which are also the 3 most feared questions for sales personnel of hydraulic cartridge valve manufacturers, and the 3 most difficult questions to answer. The 1st question, just ask the price, how much is this hydraulic cartridge valve? How should the sales personnel of the hydraulic cartridge valve manufacturer respond? The 2nd question is that your price is more expensive than another hydraulic cartridge valve manufacturer. That is, the hydraulic cartridge valve manufacturers in the same industry are cheaper than yours. How should the sales personnel of the hydraulic cartridge valve manufacturers respond? The 3rd question is, after receiving the reduced price, asks again, could you make it a little cheaper further? How should the sales personnel of the hydraulic cartridge valve manufacturers respond? The above are the 3 most frequently asked questions by customers that I have summarized, and they are also the 3 most difficult questions for sales personnel from hydraulic cartridge valve manufacturers to answer. If there are any other questions that are most afraid of by the colleagues from hydraulic cartridge valve manufacturers, you can leave a message for us to discuss together. Hydraulic cartridge valve manufacturer AAK, is most afraid of the 3 questions from customers.

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
