Valves

Brandon is from a hydraulic equipment manufacturing company in Colombia. In the early stage, they developed a forging hydraulic press. The main selling point is: high speed when unloaded, and low speed when overloaded. The engineer has high requirements for the hydraulic cartridge proportional valve used and reminded Brandon to find a reliable manufacturer of the hydraulic cartridge proportional valves. Brandon chose a manufacturer who worked with their company for 5 years to sample the hydraulic cartridge proportional valve. During testing, the equipment was not smooth, especially in the process of pressure relief, the pressure and flow impact was large, the noise was loud, and the abnormal flow lead to the unstable speed of the equipment. The engineer required that the hydraulic cartridge proportional valve must be optimized. The original manufacturer had to give up after 30 days of trying, and Brandon was worried. Brandon clicked on AAK's article about hydraulic cartridge proportional control valve in B2B and left a message: Can you customize a hydraulic cartridge proportional valve with small pressure impact and accurate flow control? After communication, we learned that the original cartridge valve manufacturer could not optimize the structure. After checking his hydraulic cartridge proportional valve drawings and equipment work videos, I told him that optimizing structure was the only solution, but not 100% confidence, then no further email from Brandon. 2 weeks later, he suddenly asked about the lead time and development cost for the customization. After 35 days, AAK sent 8 hydraulic cartridge proportional valve samples. 1 month after the samples were sent, Brandon sent an email to inform that their engineers were very satisfied with the hydraulic cartridge proportional valve optimized by AAK, and the equipment was successfully debugged and was in market promotion stage. They believed that the pre-sales would not be low. AAK hydraulic cartridge proportional valve can ensure small pressure impact and accurate flow control during pressure relief. We optimized it as follows: 1. 4 symmetrical waist shaped holes were processed on the valve sleeve, which can reduce the pressure impact and sudden change of speed of the oil near the valve port, and also reduces the energy loss of the oil in the flow process. Most hydraulic cartridge proportional valve manufacturers use round holes, which are easy to process. 2. The displacement of the valve spool is controlled by the pilot control mechanism. The oil flows into the two closed areas composed of the valve spool, the control cover plate and the valve sleeve through the control cover plate, and the valve spool moves up and down through the differential pressure of its oil. 3. The valve cover is equipped with a displacement sensor to detect the displacement of the valve spool in real time, and the high-precision linear control can meet the characteristics of flow gain and smooth flow, and reduce the pressure impact during the pressure relief process. AAK hydraulic cartridge proportional control valve, with small pressure loss and precise control, you can also have a small try! https://www.aakindustry.com/info-detai , l/cartridge-proportional-valves-aak422

To be sure, there are many small and medium-sized factories with their own proprietary technologies in China, such as industrial products manufacturers with their own traditional technologies such as hydraulic valves. It is unlikely that Southeast Asian countries will replace China in 30-50 years, although consumables are gradually being replaced. Therefore, I am optimistic about China's hydraulic valve manufacturers, especially those with some proprietary technology. Over the past 13 years, AAK has adhered to 3 lines: R & D, innovation and manufacturing capacity: 1. AAK Hydraulic Valves maintain the trend of being specialized and strong. I call it "both specialized and strong". Instead of giving priority to the development of manufacturing scale, we invest money in the research and development of hydraulic valves, spend time on the innovation of hydraulic valves, and spend energy on the manufacture of hydraulic valves. Most of the manufacturing industries have learned too many lessons from "big to die". 2. AAK focuses on the R & D and innovation of hydraulic valves. It focuses on both technology and quality, and strives to be strong on both sides. Its quality benchmarks the international first-line hydraulic valve brands. The performance and function of some hydraulic valves have exceeded the domestic head hydraulic valve manufacturers, especially in the vertically segmented niche market, such as high-pressure hydraulic valves. 3. Although the production scale of AAK Hydraulic Valve maintains the original situation, there is still room for urgent orders and special orders of old customers. For industrial products, especially machine parts such as hydraulic valves, in marketing, you will find that it has nothing to do with the theories of Trout and Kotler. AAK hydraulic valves adhere to: 1）Focus on large hydraulic valve products and become our own core competitiveness. 2）The manufacturing quality of hydraulic valves, the price positioning of hydraulic valves, and the target customers constitute a triangle of a manufacturing enterprise. 3）Marketing, promotion and sales constitute a triangle of hydraulic valve business. I have always called on hydraulic valve manufacturers to improve the material grade and produce high-quality hydraulic valves, but few hydraulic valve manufacturers follow suit. Why? Because the manufacturers of hydraulic valves have extremely fierce price competition, even if you do it, you may not be able to make money after all the hardships. However, AAK hydraulic valves are used by 7 of the world's top 500 companies. For 9 consecutive years, AAK hydraulic valves have been HydraForce supplier of hydraulic valves. Moreover, AAK hydraulic valves never do market common quality, price comparison and credit business. In the face of such a competitive hydraulic valve market, why does it have no impact on the sales of AAK? Because this market is too large, the sales volume of AAK hydraulic valves is also insignificant in the high-end market of hydraulic valves. Of course, the manufacturing quality of my hydraulic valves is among the top 1%. In addition to the repurchase of AAK hydraulic valves by our old customers and our promotion soft power on Google, AAK hydraulic valves can have a fairly good life. AAK hydraulic valve, a unique road, is supported by our soft power. We insist on only cooperating with high-quality hydraulic valve customers. https://www.aakindustry.com/info , -detail/hydraulic-valves-aak311

Madison is from WHITE company in the United States. 1 year ago, he found AAK Hydraulic Valves through Google. He wanted to develop a hydraulic pilot operated relief valve. After 2 rounds of PK, AAK hydraulic valves stood out from more than 30 hydraulic valve manufacturers and received the trial order for 30pcs of hydraulic pilot operated relief valves. The trial order requires that all parameters must be benchmarked with HydraForce. I replied that AAK Hydraulic Valves is the supplier of HydraForce for 9 consecutive years. The quality of HydraForce is the most basic commitment of AAK. 1 month later, 30 samples of hydraulic pilot operated relief valves were sent out, and Madison had no response. I did't have any follow-up. As long as these samples are approved by the customer, the customer will actively feedback the test results and will come to re-purchase this hydraulic pilot operated relief valve. 1 year later, that is, yesterday, I received Madison's e-mail. I knew that it must be the re-order before I did not read the email. Madison said that after 1 year's use, AAK hydraulic pilot operated relief valve has reached the standard, and 800 more hydraulic pilot operated relief valves are needed. Madison also specifically mentioned that AAK hydraulic pilot operated relief valve is completely comparable to HydraForce in quality and function, and the internal leakage control is 20% higher than that of HydraForce, and the performance is more than 2 million times. In the past year, AAK Hydraulic Valve was the most satisfied hydraulic relief valve manufacturer of their entire technical team. Not only did the manufacturing quality match the standard of HydraHorce, but also the price was about 30% cheaper. I know that there are many hydraulic valve manufacturers in Ningbo, but there are not many hydraulic valve manufacturers such as AAK that insist on "high quality, excellent function and strong performance", perhaps not more than 3. In my early years, I understood the importance of choice from the Scrolls. One's greatest strength is the power of choice. Since its inception, AAK has made a quality positioning for hydraulic valves, which makes AAK become one of the suppliers of six top 500 enterprises in the world. AAK's strength mainly depends on 3 important points: human, machine and material: 1. AAK engineers have more than 20 years of industry experience, not only have strong design and R & D capabilities, but also know the details of each processing of products. 2. In terms of finishing equipment, AAK has the NP520X-F full-automatic universal grinder of Japan Long Island, which can achieve μ surface of the processed valve spool is like a mirror, and the precision control is excellent. 3. AAK's selection of materials will be strictly based on the customer's working conditions and requirements, including German 20CrNi2MoV high-carbon bearing steel with high wear resistance and contact fatigue resistance, 18Cr2Ni4WA high-strength alloy carburized steel etc., and most of the hydraulic valve manufacturers use 45 steel or free cutting steel. AAK hydraulic pilot operated relief valves, high quality, excellent function, strong performance, you can also try a small one! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-relief-valves- aak31 , 0

In March this year, Danielisadora, a Brazilian customer, sent us an inquiry, urgently needing 20 non-standard customized hydraulic flow control valves with an accuracy of 1.0μm valve hole, which is required to be completed within 1 month. Danielisadora has not cooperated much with AAK. Previously, he purchased some SUN hydraulic valves in small quantities but with high requirements. For 20 small quantities of non-standard customized hydraulic flow control valves, most hydraulic valve manufacturers were unwilling to do. After several rounds of email communication, we learned the difficulties that Danielisadora has met. In the second half of last year, Danielisadora developed a high-performance excavator, which needs a high-precision hydraulic control system as a support, reflecting the high-speed, heavy load and accurate displacement of the equipment. However, the equipment is not smooth in the commissioning stage, and the buffers at both ends of the excavator stick cylinder often fail. Their engineer was puzzled. After disassembling the hydraulic system, it was found that there was a little leakage in the hydraulic flow control valves on the oil cylinder, which was caused by the valve hole accuracy of the hydraulic flow control valves exceeding 1.0μm. The boss asked Danielisadora to solve the problem quickly, because it will miss the exhibition period after 50 days. According to the feedback of the original manufacturer of hydraulic flow control valves, he has no ability to meet the accuracy standard of the 1.0μm valve hole now and has to give up. Danielisadora was helpless. 1 week passed, no manufacturer is willing to try the order of hydraulic flow control valves. The boss had pushed the progress twice, and Danielisadora was under great pressure. Danielisadora sent me an email and urgently needed 20 non-standard customized hydraulic flow control valves with the accuracy of 1.0μm valve hole. He said that the SUN hydraulic valves shipped by AAK have never been complained about its accuracy. Frankly speaking, the 1.0μm valve hole accuracy of hydraulic flow control valves is not too difficult for AAK. After 30 days, 20 high- precision hydraulic flow control valves were delivered. Half a month later, Danielisadora informed that AAK hydraulic flow control valves were installed on the equipment, and the equipment abnormality happened last time was solved. Now the equipment commissioning was successful, and the valve hole accuracy of AAK hydraulic flow control valves was all 0.8μm, while the other hydraulic valve manufacturers connect meet the accuracy standard of even 1.0μm. AAK has owned a high-precision honing machine imported from Switzerland as early as 3 years ago, and is equipped with HDK diamond reamer. This reamer is especially skilled in high precision. The roundness of the front and rear guide is 0.005mm, the cylindricity is 0.005mm/100mm, and the roughness of the front guide is Ra0.63μm. Roughness of rear guide excircle Ra0.16μm. The coaxiality between the tool handle and the front and rear guide parts reaches 0.015mm; Therefore, the aperture accuracy of the machined workpiece can be guaranteed to be within 0.8μm, the surface roughness of reaming the aperture of hydraulic flow control valves can reach Ra0.2. A few hydraulic valve manufacturers may have high-end processing equipment, but for those with HDK diamond reamers, there will never be a third one in Ningbo. Danielisadora privately informed that the boss now attaches great importance to him, and he is responsible for all the purchases with some difficulties. AAK Hydraulic Valves is now his preferred hydraulic valve manufacturer for cartridge valves. AAK hydraulic flow control valves, with valve hole accuracy within 0.8μm, and 3drops/min, benchmarking with HydraForce quality, there are few rivals, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-flow-control-valves-aak309

Faraji is from South Africa, and fell down when he purchased hydraulic cartridge valves from China in the first time. Last September, Faraji purchased a hydraulic cartridge valve from China and used it in their hydraulic manifold. After more than 1 month of operation, it was discovered that the hydraulic cartridge valve was leaking, with foreign objects remaining between the valve spool and valve seat, causing the valve to get stuck. The original hydraulic cartridge valve manufacturer shifted the blame and said that it was caused due to the uncleanness of the hydraulic oil. Faraji felt helpless. I'm not sure where Faraji learned about AAK hydraulic valves. He left a message on our website: Can AAK ensure that each hydraulic cartridge valve has no residual impurities? There are not many messages about residual impurities in the valve. After communication, it was learned that he encountered problems when purchasing cartridge valves from other hydraulic cartridge valve manufacturer in China. He may have encountered a manufacturer who does not pay attention to quality, or always thought that African customers do not pay attention to quality. The hydraulic cartridge valve required by Faraji is a standard part of SUN Hydraulics's RDDA series, and we have program for this model. In 1 week, AAK sent out 30 samples of RDDA hydraulic cartridge valves. 6 months later, which was last week, Faraji informed us via email that the AAK hydraulic cartridge valve did not experience any jamming, and the valve produced by the original manufacturer was stuck in over 1 month. I told him that no customer has complained that the AAK hydraulic cartridge valve has stuck within 1 year. In fact, it is not difficult to solve the residual in the hydraulic cartridge valve, but most hydraulic cartridge valve manufacturers in China cannot do it well. AAK independently developed an automated ultrasonic assembly line 6 years ago, to clean each processed component. There are 4 procedures, one linked with another, without the need for manual labor. 1. First, degrease. We do this by immersing each component in a degreasing tank for more than half an hour, to ensure that the surface oil stains of each component are completely removed. Most manufacturers directly overlook this action. 2. After oil removal, it automatically enters the ultrasonic cleaning tank. By utilizing ultrasound, the direct inflow effect in the liquid disperses, emulsifies, and peels off impurities on the surface of the component. 3. After ultrasonic cleaning, the components automatically enter the rust prevention tank for rust prevention treatment, improving the corrosion resistance of each component. 4. Finally, each component enters the automatic drying tank for drying. After 100% drying, proceed to the assembly workshop. AAK hydraulic cartridge valves are cleaned by 4 procedures that do not require manual operation, which not only has high production efficiency, but also ensures 100% residue free and no worry about valve stuck. AAK hydraulic cartridge valve, no residue, no stuck, you can also give it a try!

This week, we’d like to introduce a cartridge valve equivalent to HydraForce FR12-33. It is a screw-in, an adjustable, pressure compensated, priority type with reverse flowcheck flow control valve. The regulated flow increases from closed to fully open with counter-clockwise adjustment rotation. The valve will maintain the set flow regardless of pressure variations on the regulated or bypass port. Last May in 2022, a hydraulic cartridge valve customer in Russia found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He sent us an inquiry for 5 pcs of HydraForce cartridge valve FR12-33, with an annual demand of 500 pcs. Previously, their company purchased it from an Italian supplier. For this model, several cartridge valve manufacturers in Ningbo have existing production procedures. This Russian customer ordered 5 pcs from each factory, they will test them for 1 year, and chose one to place the annual order. Last week, we were very happy to learn from the Russian customer that AAK cartridge valve E-FR12-33 has passed their internal testing after 1 year of use, the function and performance is the best among the several manufacturers. The samples from some manufacturers leaked or blocked in less than 1 year. AAK hydraulic cartridge valve E-FR12-33 two advantages: 1. Pressure Rating 240 bar (3500 psi), benchmarking HydraForce 2. Its service life is 2 times that of its domestic peers Technical parameters of AAK E-FR12-33 flow control cartridge valve: Pressure Ratings: 240 bar (3500 psi) Flow Ratings: 0-68 lpm (0-18 gpm) Note: Priority + bypass, 3-ported 0-45 lpm (0-12 gpm) Note: Bypass closed, 3-ported Inlet Flow Rating (Priority + bypass): 76 lpm (20 gpm) Note: Nominal 114 lpm (30 gpm) Note: Maximum Internal Leakage: 100cc/minute (6 cu.in./minute) at 207 bar (3000 psi) Required adjustment torque: 1.7 Nm (15 in.-pounds) at 207 bar (3000 psi) Temperature: - 40 to 120 °C Cavity: 12-3 AAK E-FR12-33 flow control cartridge valve, benchmarking HydraForce FR12-33, has been approved by customer in Russia after 1 year of testing.

AAK hydraulic cartridge valves, the foothold of manufacturing quality, I have no peers; AAK hydraulic cartridge valves, the foothold of marketing, I have no peers; AAK hydraulic cartridge valves, the foothold of promotion, I have no peers. Lim, from the United States, is the second customer of AAK hydraulic cartridge valves. We are friends who can talk about everything to each other. A few days ago, he agreed very much that AAK has no peers, and also wanted to copy this idea into his hydraulic equipment system, but he didn't know how to start. What I want to say is that this is a system project, which not only needs time, but also needs to stick to 5 aspects. I have no peers, and it is not difficult to understand that there are no two identical leaves fall from the same tree. Even twins cannot be identical from appearance, personality to fingerprints. From a physical point of view, there is no peer for products or equipment. The key lies in your manufacturing quality, promotion and marketing foothold. I have no peers, which is very against common sense. Most people will question why you don't have a peer? In fact, after questioning, the effect will come. When you say that there is no peer for hydraulic cartridge valves; Hydraulic manifolds, no peer; Hydraulic valve blocks, no peer, and this effect will come, at least, to catch the eye. Note that it is not common sense to look at it. From the perspective of physics, AAK has no peers, which is certain. From the point of view of physics, is it possible to find an identical peer for the hydraulic cartridge valve itself? Take raw materials as an example, our steel are purchased in the same steel factory. Is the steel produced in the same furnace? Even if the steel produced in the same furnace or in the same batch. When steel arrives in your factory and my workshop, will the hydraulic cartridge valves we produce be the same? Certainly not, because our hydraulic cartridge valve process will be the same? Will the machining accuracy of hydraulic cartridge valve be the same? Will our quality control process be the same? Generally speaking, there are no two identical leaves even from the same tree, can you find them? Twins, even though their looks and personalities cannot be distinguished, their fingerprints cannot be identical. From what perspective? What I appreciate is the features of AAK hydraulic cartridge valves, the advantages of AAK hydraulic cartridge valves, and the benefits that AAK hydraulic cartridge valves bring to customers. If we look at the hydraulic cartridge valves only from the perspective of common sense, it is difficult to select a hydraulic cartridge valve manufacturer with high quality. In fact, AAK hydraulic cartridge valve has always described our products from these perspectives. We put it in practice that AAK have no peers. Raw materials, process, technology, equipment, and quality control are the 5 major aspects that we uphold. We distinguish peers from each other in 5 directions, and the manufacturing quality of AAK hydraulic cartridge valves will have a clear positioning. With the quality positioning, there will be a price positioning, and with the price positioning, there will be a target customer positioning. What is the target customer? In my definition, I never care about the size of the customer who has requirements for quality and can afford the order. What I care about is whether he has requirements for quality and can afford the order. AAK hydraulic cartridge valves, no peers. https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valve- manufacturers-aa , k493

Last Friday, we received an annual order of 3,600 hydraulic needle valves from Paschalis, probably the new large-scale combine harvester of their company won a large order at the exhibition. Paschalis is from Greece and has been cooperating with AAK for 5 years. At the beginning of this year, the newly developed harvester of their company plans to appear at the agricultural machinery exhibition. In order to shorten the development time, they asked a local hydraulic needle valve manufacturer to make samples. The test run was not smooth, and the flow of the hydraulic system is unstable, resulting in the low accuracy of the equipment action. Their engineer judged that the processing accuracy of the orifice diameter of the hydraulic needle valves did not meet the standard. The hydraulic needle valve manufacturer replied that this is a large flow hydraulic needle valve, and the orifice is also a large aperture, which is difficult to process. At present, the equipment can only guarantee the accuracy like the sample. Paschalis had to find a new supplier of hydraulic needle valves. And contacted more than 10 local manufacturers. Most of them said that they are not able to make the hydraulic needle valves with this kind of large aperture and accuracy below 1.0μm. Only one manufacturer can guarantee it, but it takes 3 months to develop, and will miss the exhibition. The engineer has pushed for the progress for several times, but Paschalis has not determined the manufacturer yet, so he is in a hurry. His supervisor reminded him that purchasing hydraulic needle valves from overseas may be faster and more awesome than domestic manufacturers. At this moment, Paschalis thought of AAK, and immediately sent an email for inquiry, with the hydraulic needle valve drawing attached, specifically stating that this hydraulic needle valve has a large aperture, but the accuracy needs to be within 1.0μm. Moreover, only 1 month can be given for development. After discussion, our technical team replied that the samples would be sent within 30 days. 2 weeks after the samples were sent, Paschalis emailed us that their test run was very smooth, and their engineers also specially tested the large aperture of AAK hydraulic needle valves, all with an accuracy below 1.0μm. Next, they can rest assured to hype it up at the exhibition, and AAK can wait for the annual large order of the hydraulic needle valves. In recent years, some customers of AAK have higher and higher requirements for the accuracy of the large flow hydraulic needle valves with large aperture. Our machining equipment, especially honing equipment, also keeps pace with the times. At present, RS series single stroke sequential honing machine imported from Switzerland adopts the casting structure of base, column and headstock, with stable accuracy; Each spindle is equipped with a separate servo motor, which can feed back torque in real time; The maximum honing diameter can reach 50mm and 80mm, the maximum honing depth can reach 150mm, the stroke speed is 20m/min, and the machining accuracy is as high as 0.5-0.8μm. It is especially suitable for processing the large orifice of large flow and high-precision hydraulic needle valves. AAK hydraulic needle valve has defeated Greek hydraulic cartridge valve manufacturers with accuracy. You can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-needle-valves-aak308

At the beginning of this year, Timoteo emailed us to asked about the production time for 600 hydraulic relief valves, and it required that the quality and parameters should be same as those of the previous samples, especially that the valve hole accuracy must be 100% within 2μm. Timoteo is from Italy and has been cooperating with AAK for more than 1 year. After communication, we learned that the price of this hydraulic relief valve that was previously tested in AAK was 20% higher than that of another hydraulic cartridge valve manufacturer, so they did not purchase the larger quantity from AAK. However, the hydraulic relief valves purchased from another manufacturer have been complained by customers one after another. These hydraulic relief valves were used in shield machine. The valve hole accuracy of some of these hydraulic relief valves is over 2μm and caused equipment failure due to leakage. Per the original manufacturer, this hydraulic relief valve has a very high accuracy requirement. It is not avoidable that a little proportion of the goods does not meet the accuracy standard, they can be replaced free of charge. But after more than half a year, the high-frequency replacement makes the customer unhappy. His boss asked Timoteo to replace the hydraulic relief valve supplier immediately, and the valve hole accuracy must be 100% within 2μm. Timoteo can only contact AAK, because during the testing stage, the valve hole accuracy of AAK hydraulic relief valves were all within 2μm. Timoteo also frankly told us that he should not have determined the hydraulic relief valve supplier blindly based on price only. After 30 days, AAK shipped 600 hydraulic relief valves. Until today, Timoteo emailed us that AAK hydraulic relief valves have been installed on the equipment for more than half a year, and no customer has complained. The boss is very satisfied. I told him that as long as they are used properly, there should be no leakage in another year, because the hole accuracy of AAK hydraulic relief valves is 100% within 2μm. Among so many hydraulic valve manufacturers, why only AAK can achieve 100% accuracy guaranteed hydraulic relief valves? For the quality control of hydraulic relief valves, AAK has 3 advantages, and I believe most hydraulic valve factories do not have these 3 characteristics of AAK. 1、The valve hole of AAK hydraulic relief valve is precision machined with TAMIX one-time tool walking high-speed ultra precision honing mill imported from Japan, which is thoroughly ground without trace. In mass production, the wear-resistant SPA cutter effectively ensures the stability of processing, and the accuracy of valve hole is guaranteed to be within 1-2μm, the surface roughness reaches Ra0.2-0.3. 2、After the valve hole processing is completed, AAK inspectors use the Diatest small micropore diameter high-precision measuring instrument imported from Germany to accurately measure each hydraulic relief valve hole, and the minimum measurement accuracy range can reach 0.1μm, so as to ensure that the accuracy of each valve meets the standard. 3、AAK has independently developed hydraulic relief valve durability test equipment, which can fully carry out fatigue test on valves according to customer specified requirements in combination with NFPA/T2.6.1 standards. Each valve must be inspected to ensure that each hydraulic relief valve is qualified before shipment. AAK hydraulic relief valves, the accuracy meets the requirements 100%, High Accuracy and Stability, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak307

For a hydraulic cartridge pressure control valve with 3 high accuracy requirements, Jack spent 2 months on 3 cartridge valve manufacturers but the samples from all 3 factories failed. AAK completed the hydraulic cartridge pressure control valve with the main hole length diameter ratio of 10 in 25 days, and the main hole diameter tolerance is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra 0.2μm. Jack, from Melbourne, has been engaged in the procurement of hydraulic cartridge valves for nearly 3 years, with favorable wind and favorable water. Recently, he was trapped in troubles on the order of a hydraulic cartridge pressure control valve. His customer has strict requirements on the diameter tolerance, cylindricity and surface roughness of the main hole of the hydraulic cartridge pressure valve. He specially arranged 3 cartridge valve manufacturers to make samples at the same time. After 45 days, samples from only 1 of the 3 factories met the customer's requirements. However, in the first small batch order, the qualification rate of 120 hydraulic cartridge pressure valves was less than 60%. The customer requested to replenish the products, but the manufacturer had been prevaricating. Jack realized that he could only retain the customer by replacing the manufacturer of the hydraulic cartridge pressure valves. Jack browsed the website of AAK hydraulic valves through B2B and found that AAK had produced hydraulic cartridge valves with high precision in cylindricity, roughness and aspect ratio. He felt that perhaps only AAK can help him. He directly emailed us the complete drawings of hydraulic cartridge pressure valves. After several rounds of communication, I suggested Jack directly order 60 hydraulic cartridge pressure valves, which can be completed in 25 days. Maybe the trust level hasn't arrived yet, I did not hear from Jack for a week and did not push him. A week later, he suddenly sent the PO of 60 hydraulic cartridge pressure valves. Today, that is, 4 months after the 60 hydraulic cartridge pressure valves were shipped, Jack sent another PO for 300 hydraulic cartridge pressure valves of the same model. Jack's customers are very satisfied with AAK hydraulic cartridge pressure valves, and the 3 accuracies are all qualified. The diameter tolerance of the main hole of the hydraulic cartridge pressure valve is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra0.2μm. The customer should quickly replenish the inventory and designate AAK for production. AAK hydraulic cartridge pressure valve, meeting 3 precision standards, and is stable, because there are 3 guarantees in production: 1.Diamond reamers are used instead of conventional aluminum alloy reamers to avoid tool wear and effectively ensure the accuracy and quality of holes. 2.Set the best reamer parameters to ensure the form and position tolerance. The speed is 80-120 r/min, and the feed rate is 0.30 min/r. 3.90% of the medium oil is dissolved in 10% of the vulcanized chip liquid as the coolant to promote heat dissipation during processing, extend the service life of the tool, and protect the processing. AAK hydraulic cartridge pressure valve, is high-precision and stable. Welcome you to try an order! https://www.aakindustry.com/info-det , ail/cartridge-pressure-valves-aak421

James, a Brazilian customer, was in urgent need of purchasing 200 hydraulic relief valves within 30 days some time ago. The hydraulic valve manufacturer he chose to cooperate with got stuck in the hydraulic relief valve sample stage. The first time to send samples, the time was delayed by 10 days, and the hydraulic relief valve hole was also seriously deformed. The manufacturer said that the current processing of this valve hole was their limit, and asked James to contact other hydraulic cartridge valve manufacturers to take samples. James was speechless, and time was wasted. He consulted more than 10 hydraulic relief valve manufacturers and was advised that they were not able to meet the valve hole requirements, which made James a headache. James contacted his German friend Logan and hoped to get his help. Coincidentally, Logan is our customer for several years. He recommended AAK to James. When I received the hydraulic relief valve drawing sent by James and learned that he had no factory to cooperate with to make samples, I felt that it was a hot potato. After the discussion of AAK technical team, I told him that AAK has unique skills to solve the deformation of the hydraulic relief valve hole, but the production time will be at least 22 days. James had no choice but to wait patiently for the hydraulic relief valve sample of AAK. The processing of this hydraulic relief valve is still a little challenging for us. After the first sample is completed and assembled, the hydraulic relief valve hole also shows deformation under the influence of assembly force. When the assembly tightening torque is 90N·m*, the valve hole deformation reaches 0.013~0.015mm. In view of this data comparison, we will know how to improve. After 4 days, AAK sent 5 samples of hydraulic relief valves. On the second day after receiving the sample, James informed that the valve hole was not deformed and that mass production could be started. 2 weeks later, 200 hydraulic relief valves were shipped on time. AAK can effectively solve the deformation of the valve hole of the hydraulic relief valve because as early as 3 years ago, we explored a set of effective processing procedures: pre assemble the valve body first, and then place it for 2-3 days. Before honing, rough ream it with a diamond reamer, correct the roundness deviation of the valve hole caused by assembly preload and creep, and then honing. The core of this technical point is honing, most hydraulic relief valve manufacturers are stuck here. Not only to ensure the honing effect and honing efficiency, but also to reduce the impact of creep on the accuracy of the valve hole. Honing is not only a good honing equipment support, a good technician, but also a unique skill.

We are troubled by a widespread paradox: the opportunities for Chinese hydraulic manifold manufacturers are decreasing. If I had built a piece of land 20 years ago, I wouldn't have established a Chinese hydraulic manifold manufacturer. 10 years ago, if I was to use the internet, I wouldn't have developed Chinese hydraulic manifold manufacturer. Last year if I bought Tesla stocks, I wouldn't pay attention to the orders of Chinese hydraulic integration manufacturer AAK anymore, This kind of frustration will persist. It is easy to infer that there is a huge opportunity now that will be envied by people 10 years from now.   In 2014, my mother came to live at my house and I planned to open a vegetable plot in the backyard to add some fun to her unfamiliar city life. But at that time, I was about to switch to a different house, and it was highly likely that the house had just been sown, and the owner had already changed, so I gave up. Who knows, the house to be changed was not negotiated at the last minute, and the time for farming was also missed. After delaying for a year, I decided to develop a vegetable field. I was just about to start, because I wanted to purchase equipment for AAK, a Chinese hydraulic manifold manufacturer. The money was not enough, so the house change was put on hold. Things are unpredictable. Due to the decline in real estate in Ningbo, the original house was on sale for 2 years. Mom was in the backyard every day, staring at the green grass that cannot be eaten or moved in a daze. 3 years later, the house was sold. But the renovation of the new house takes 2 years, and the buyer of the old house is willing to let us rent back for 2 years, which means that 5 years of vegetable planting time were wasted in the old house. For a whole of 5 years, we can all eat organic vegetables that our mother has personally grown, and our mother can dispel boredom and stretch her muscles and bones in the work of an alien land. If you stand on the other side of time, you already have the answer. As long as you stay here for a while, hurry up and open the vegetable field, you won't miss it or make mistakes. AAK hydraulic valve, from supplying domestic listed companies to focusing on overseas trade, took 3 years. AAK, from a Chinese hydraulic cartridge valve manufacturer to a Chinese hydraulic manifold manufacturer, took 5 years. In 2012, Honeywell's purchaser suggested that AAK develop hydraulic manifolds, but I shelved it due to market conflicts with the client. 1 year later, after reaching a consensus with the client, AAK, a Chinese hydraulic manifold manufacturer, was prepared to be established. However, the landlord of the factory proposed to use the factory himself, and AAK had to wait for 2 years to move to a new factory. After the new factory building of Chinese's hydraulic manifold manufacturer AAK was put into operation in 2015, it was ready to invest in equipment, but there was no money to buy Japanese equipment. During this period, I could only stare blankly at the hydraulic manifold inquiry sent by the customer, until 2017, when all the equipment was available, people were available, and orders were placed. If I were on the other side of time, I would have had the answer long ago. As long as the factory is in operation and customers have needs, I would quickly start a new project. This way, customers will not be missed, and Chinese hydraulic manifold manufacturer AAK will not be at fault.   The so-called fatalism is like this: you cannot change the future, because your change is also a part of the future. People can go back to the past, but it cannot change the course of history. If we could go back to the past, even if you choose those decisive turning points in life, such as a certain exam, choosing a major, pursuing a career, and marrying someone etc., you can make the right decision again, but your destiny in this life may still be unchangeable, as your own system structure rushes towards an irreversible fate. That's why the fate of those grand prize winners is often tragic. Of course, if you have the right attitude, interesting things will naturally find you.   Chinese hydraulic manifold manufacturer AAK, has a story, a correct attitude, and awaits interesting things.

Last week, the Spanish customer Salvador sent an inquiry for a hydraulic valve block, which was the inquiry for the 4th time, and the inquiries in the first 3 times have already been placed orders for. Salvador has been engaged in the purchase of hydraulic valve blocks for many years, and it has been successful. In March this year, they developed a large multi cylinder hydraulic cone crusher, which requires a hydraulic valve block weighing 1.5 tons. Salvador found a factory in the United States to make samples, and the equipment was successfully tested. 2 months after the promotion, there was a customer's reservation, but the price needed to be reduced by 15%. After costing, the boss asked to reduce the cost of the hydraulic valve block by 10%. Salvador contacted the manufacturer of hydraulic valve blocks in the United States, but the manufacturer refused to reduce the price. The boss asked Salvador to find a new manufacturer. Salvador contacted the all their current suppliers of the hydraulic components. None of them were able to produce the hydraulic valve blocks weighing 1.5 tons, unless to find a professional oil circuit block manufacturer. Salvador found AAK in Google and sent an email inquiry with a try attitude. I replied to him that AAK has not processed the hydraulic valve blocks of more than 1 ton, but AAK is capable of processing this hydraulic valve block, and the accuracy of the valve hole absolutely meets the IT7-8 standard, and the roughness can reach Ra0.2-0.4. After receiving the quotation from our cost accounting department, Salvador was a little surprised. After confirming that it was correct, he immediately placed order for 5 hydraulic valve blocks and paid the development cost. After 25 days, AAK delivered 5 hydraulic valve blocks. 2 weeks later, Salvador informed by email that the hole accuracy of AAK hydraulic valve block absolutely met the IT7-8 standard, and the roughness could reach Ra0.2-0.4. After it replaced the hydraulic valve blocks of the original American manufacturer, the equipment still operated normally. His boss was very happy to find a hydraulic valve block supplier benchmarking the American manufacturer, and the price was 30% lower. AAK owns the full hydrostatic heavy 5 axis gantry machining center of INNSE Berardi, Italy. The column moves and the hydrostatic guide rail is preloaded. It is suitable for processing large hydraulic valve blocks with guaranteed accuracy. The machine tool can be equipped with a fixed or working beam (W- axis), and the special detection device can compensate the thermal drift, so that the tool can have high operation accuracy. The coordinate axis runs on the preloaded hydrostatic guide rail to ensure maximum rigidity and balance of operation. AAK hydraulic valve blocks, 5 axis gantry machining center, welcome to have a try! https://www.aakindustry.com/info-d , etail/hydraulic-valve-blocks-aak305

Kaka is from Brazil. When he left a message and his signature on AAK hydraulic valve website, I thought of Kaka playing football. He encountered confusion about the service life of the locally purchased hydraulic cartridge solenoid valve. Their hydraulic power unit requires the use of a hydraulic cartridge solenoid valve benchmarking HydraForce, and he purchased the existing copy stocks from a local hydraulic valve manufacturer in Brazil. 6 months later, there were complaints about severe wear and leakage of the cartridge solenoid valve body. The original cartridge solenoid valve manufacturer said that due to poor working conditions, the only solution is to replace the valves with new ones. But it wasn't long before the old problem recurred. The customer was very dissatisfied and requested that the service life of the cartridge solenoid valve be at least 1 year, but the original manufacturer did not cooperate, making Kaka anxious. Kaka discovered AAK hydraulic valve on Google and left a message asking: Can AAK ensure that the service life of the cartridge solenoid valve is at least 1 year under high friction and high-frequency use? Especially the cartridge solenoid valve body needs to be wear-resistant. Upon seeing this message, I speculated that the selection of materials for the original cartridge solenoid valve was not targeted and only followed the industry standards. After communication, it was learned that he encountered the dilemma of the valves not being wear-resistant when purchasing from local hydraulic valve manufacturer in Brazil. This model is a HydraForce standard part and AAK have it in stock. But for his working conditions, we cannot simply use 40Cr alloy steel to produce the body of this cartridge solenoid valve. Kaka may have realized that I came to the point and requested AAK to make 30 samples of the cartridge solenoid valves first. 2 weeks later, AAK sent out the cartridge solenoid valve samples. Last week, Kaka placed a PO for 360 cartridge solenoid valves, which indicates that AAK hydraulic cartridge solenoid valve has passed the test with a service life of over 1 year. After confirming the delivery time for the first order, he told me that the customer is very satisfied with AAK cartridge solenoid valve, which is not only wear-resistant, but also leak free, and has no abnormalities within 1 year. We have chosen high-strength alloy steel instead of the industry's 40Cr alloy steel to produce the body of this cartridge solenoid valve. The surface treatment of steel adopts electromagnetic induction heating, and the surface oxidation and decarburization of the workpiece are relatively light. The surface hardening layer is easy to control, and the hardness and toughness are high, increased by more than 30% compared to conventional heat treatment processes. Especially during induction heating surface quenching, the workpiece generates internal stress and improves its fatigue resistance. Therefore, the wear resistance of high-strength alloy steel treated in this way is 8-10 times that of the original 40Cr alloy steel. In the wear-resistant aspect, AAK cartridge solenoid valve can be used for 3 years without any trouble. AAK hydraulic cartridge solenoid valve, wear-resistant for 3 years without any trouble, you can also give it a try!
