Joakim, from Greece, got stuck when he purchased the hydraulic cartridge relief valve for the first time from China. One of their hydraulic motors needs a hydraulic cartridge relief valve. Joakim purchased it from a cartridge valve manufacturer in Ningbo. However, during the test run, the motor was damaged due to the abnormal pressure buffering function of the hydraulic cartridge relief valve, which was also blamed by the engineer. The original manufacturer was not confident to improve the pressure buffering function of the hydraulic cartridge relief valve. Joakim contacted me. I sent two customer cases of how AAK optimized the buffering function of the hydraulic cartridge relief valve to Joakim. On the second day, he asked AAK to make samples. After 30 days, AAK sent 8 samples of hydraulic cartridge relief valve. 2 weeks later, Joakim told me that the customer approved their motor, especially their engineer was very satisfied with the pressure buffer function of AAK hydraulic cartridge relief valve. In contrast, 2 advantages come out: the hydraulic system is stable and the motor performance is improved. AAK hydraulic cartridge relief valve, no impact trouble. The optimized hydraulic cartridge relief valve pushes the buffer spring at a constant speed, so that the time for the overflow pressure to rise from low pressure to high pressure remains constant. When the opening pressure is low, it gradually rises to the rated pressure, effectively reducing the impact of the moment when the motor rotates and starts. 1. AAK hydraulic cartridge relief valve is equipped with a differential valve spool with an orifice, and the annular bulge on the outer surface is used to connect the spring. 2. The buffer valve sleeve is inserted into the cavity of the differential valve spool. There is a buffer valve spool and an oil pipeline inside. There is a buffer valve spool throttle hole between the oil pipeline and the buffer valve spool. The two oil pipes inside the buffer valve sleeve are connected by two throttle holes. 3. The buffer valve sleeve and the buffer valve spool are sealed by the screw plug, and the two ends of the buffer spring are fixed in the buffer valve spool and the screw plug respectively. At the same time, the spring stiffness coefficient on the differential valve spool is greater than that of the buffer spring. AAK hydraulic cartridge relief valve, no impact, 2 advantages, you can also try it! https://www.aakindustry.com/info-de , tail/cartridge-relief-valves-aak524

Charles is a purchaser of a hydraulic pump company in the United States. He has done very well and occasionally inquires about the price with AAK HYDRAULIC VALVE. For the hydraulic check valves purchased some time ago, the production director found that 20% of the hydraulic check valves have parameters that do not meet the standard, so they must get new qualified ones to the workshop within 20 days, otherwise the delivery of customer order would be delayed. Charles asked the original manufacturer of the hydraulic check valve to complete the replacement within 2 weeks. The manufacturer is willing to replenish, but the production can be started only after 15 days, that is to say, it will take 30 days to replenish. Charles tried to find other suppliers of hydraulic check valves, and all replied that it could not be completed in such a short time. Charles realized that something was going to happen and began to look for a new hydraulic valve manufacturer, contacting factories one by one. Charles thought that AAK had also participated in the quotation of this hydraulic check valve, and the samples provided also met the requirements, but it was not considered because the quotation of AAK was slightly higher than that of other hydraulic valve manufacturers by 7%. Charles sent us an e-mail to ask whether the quotation of hydraulic check valve offered 6 months ago can be maintained, and if we can finish an urgent order of 100 hydraulic check valves in 10-12 days. I felt that this should be an order for hydraulic check valve encountered with problem. Charles told us the truth. About 20% of the hydraulic check valves produced by the original factory were unqualified and rejected by their production director. Now he must replenish them as soon as possible. General hydraulic valve manufacturers are unwilling to make such aftercare orders, but AAK HYDRAULIC VALVE don't think so, because AAK, as a production factory, has the same goal as the importer, that is to serve users well, so AAK is more willing to help customers and solve complaints from users together. Fortunately, the corresponding materials are in stock. Combined with the 24- hour production line, our production director conservatively estimates that it can be completed in 12 days. Charles asked us to start blanking now and the hydraulic check valve order will be issued tomorrow. After 10 days, 100 hydraulic check valves were successfully finished. Charles was very happy and quickly air freighted these hydraulic check valves to the United States. Thanks to the God, 100 hydraulic check valves finally arrived at their workshop in 20 days. Charles informed us by email that their engineers installed, debugged and tested AAK hydraulic check valves, which were all normal. The 7% higher price was also agreed by his boss. The boss was very amazed that AAK can deliver so quickly and the quality was better than that of the original manufacturer. AAK uses 1144 steel imported from the United States for this hydraulic check valve, which can be directly quenched. After heating to 850 ℃, it can be insulated for more than 10 hour, up to 58HRC. Usually, the ordinary factory can not control the heat treatment of this steel. The quenched 1144 steel is easy to cut, with fast cutting speed and little damage to the tool. Compared with 45 steel adopted by the original manufacturer, the production efficiency can be improved by 30%, and the strength and hardness are also stronger than 45 steel, but the cost is some high, and it is not easy to heat treat. Most hydraulic valve manufacturers dare not use this material, so most hydraulic valve manufacturers can not guarantee to complete the urgent order of this hydraulic check valve in 2 weeks. AAK hydraulic check valve, although 7% more expensive, not only has fast delivery time, but also satisfy you on the quality. You are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valve-aak131

These days, the epidemic has led to more fever cases. In a brewery in Brazil, its hydraulic station also "ran a fever”. AAK hydraulic cartridge relief valve was tailored to the case, with 3 tricks, helping Ledger's hydraulic system to be transformed successfully.   Ledger is from Brazil. Some time ago, the hydraulic system in their workshop continued to heat up, and the hydraulic cartridge relief valve of the system could not unload normally, so the pressure regulation failed. Their engineer needed to upgrade the hydraulic system and optimize the original hydraulic cartridge relief valve. The original manufacturer of the hydraulic cartridge relief valve said that it would take 2 months. The system upgrade was imminent. Ledger had to look for other hydraulic relief valve manufacturers. Ledger found me through the introduction of a local industrial product enterprise MRO. AAK is the supplier of the MRO, which purchase SUN hydraulic cartridge valves standard parts from AAK every month.   According to the drawings of Ledger's original hydraulic cartridge relief valve and the existing conditions of the hydraulic system, we were not sure about the root cause, so we asked Ledger to send us the original samples of the hydraulic cartridge relief valve. A week later, we found that the root cause of the system pressure failure was the spool of the hydraulic cartridge relief valve.   1. The accuracy of the valve spool is not enough. There is a 5% form and position tolerance and a taper, causing radial clamping. 2. The damping hole on the main valve spool is blocked, which causes that the oil pressure cannot be transmitted to the upper chamber of the main valve and the front chamber of the pilot valve, and the pressure adjustment of the main valve is lost.   I replied to Ledger that AAK had a plan to optimize the original hydraulic cartridge relief valve, and it would take 4 weeks. 2 weeks after AAK sent the optimized hydraulic cartridge relief valves, Ledger informed that after AAK hydraulic cartridge relief valve was used, the pressure of the system returned to the original 2MPa, the heating phenomenon disappeared, and various parameters met the system upgrading requirements.  AAK had a good idea. For this hydraulic cartridge relief valve, our scheme is as follows:   1. The valve spool adopts a tapered shoulder, and the small end of the shoulder faces the high-pressure area, which is conducive to the alignment of the valve spool in the inner diameter of the valve hole, ensuring the form and position tolerance, and avoiding the taper phenomenon.   2. Three pressure equalizing grooves with proper positions shall be opened on the surface of the valve spool. The depth of the annular pressure equalizing groove shall be the same, and the pressure equalizing groove shall be concentric with the outer circle of the valve spool. This process is difficult and most hydraulic cartridge valve manufacturers cannot afford it. AAK hydraulic cartridge relief valve, with this trick, solves the sticking of valve spool caused by radial imbalance force.   3. At the inlet section of the hydraulic cartridge relief valve, a welded integral high-strength filter screen and local turbulence self-cleaning function are set to reduce the impact of oil pollution on the normal operation of the hydraulic cartridge valve, and 100% eliminate the blockage of the damping hole.   AAK hydraulic cartridge relief valve, with tricks on processing, and the performance is also stable, welcome to try! https://www.aakindustry.com/info-detai , l/relief-valves-aak449

During Power transmission and control technology exhibition in Shanghai last year (PTC Asia), Italian ATOS company asked Richard to find a qualified hydraulic valve block supplier from Chinese hydraulic valve block manufacturers through the exhibition and supply for the branch in Malaysia. He spent a whole day at the exhibition. He went into almost every booth of Chinese hydraulic valve block manufacturers and selected more than 20 Chinese hydraulic valve block manufacturers. He communicated with us AAK for more than half an hour, and took some data with him. When he left, he said that AAK was the Chinese hydraulic valve block manufacturer he spent the most time today. After the exhibition, he would test samples of AAK hydraulic valve block. He would select 6 hydraulic valve block manufacturers from the more than 20 Chinese hydraulic valve block manufacturers he found. 1 week later, Richard sent us the sample drawings and working condition requirements of the hydraulic valve block. This hydraulic pump of ATOS should not only meet the international standards of ISO6020 and 6022, but also have a peak pressure of 450bar. At the same time, it has accuracy requirements for all surfaces of the hydraulic valve block. 2 weeks later, Richard received hydraulic valve block samples from 6 Chinese hydraulic valve block manufacturers. In general, there will be news within 2 weeks after the sample is sent. We asked Richard for feedback but just got reply of waiting for results. We thought it to be no results any more. 1 month later, Richard emailed that the chief engineer of the Malaysian branch advised that 3 of the 6 Chinese hydraulic valve block manufacturers met the requirements, but the accuracy of AAK hydraulic valve block was much higher than that of the other 2 Chinese hydraulic valve block manufacturers. AAK reassured them. The surface roughness of AAK hydraulic valve block flange reached Ra0 3, which is 30% more accurate than the other 2 Chinese hydraulic valve block manufacturers. At the same time, the perpendicularity between the screw hole of the pipe joint and its external fitting surface is Grade 8. The roughness of the mounting hole is Ra0 5, which is also 30% more accurate than the other 2 Chinese hydraulic valve block manufacturers. The surface roughness of O-ring groove is Ra1 5, while the other Chinese hydraulic valve block manufacturers are Ra5.0-6.5. These data of AAK have been benchmarked with their old hydraulic valve block suppliers in Germany. Richard quickly made a report to the boss according to AAK quotation and production time. The accuracy of the hydraulic valve block is comparable with that of the original supplier, but the price is 20% cheaper, and the lead time is 30-40% shorter. Richard wondered why among so many Chinese hydraulic valve block manufacturers, only AAK benchmarked the German factory? Before processing, AAK uses German COMET flaw detector to detect the blank of hydraulic valve block to ensure that the internal structure of the hydraulic valve block is dense and free of interlayer, trachoma and other defects. This step is generally ignored by other manufacturers. Then select the composite tool for processing, and combine two or more similar or different hole processing tools into one special tool. One tool can process the threaded bottom hole, 45°, 15°, R0.1 chamfering and external counterbore at the same time, and it can complete multiple processes such as drilling, expanding, reaming, spot facing and boring in the process of one machining. We don't know whether there is a second manufacturer mastering these technical essentials, maybe, maybe not. The boss was surprised that Richard found such a Chinese hydraulic valve block manufacturer and asked him to test an order for 500 hydraulic valve blocks. Richard asked AAK to guarantee on time delivery. The boss said that if it went well, he would be given a promotion and a raise. AAK is a trusted hydraulic valve block manufacturer in China. Welcome to contact us for cooperation. https://www.aakindustry.com/

It's almost the end of the year, and some hydraulic manifold manufacturers are lamenting that they can't make money because they are too honest. What I want to say is that any hydraulic manifold manufacturer who wants to make money must first have an honest heart, and then have a business acumen. But what's even more heart wrenching is that an honest heart and a business mind are two dimensions of things. Hydraulic manifold manufacturer AAK made a small profit with honesty. Because of honesty, it reduces the transaction costs for customers. I remember the first time I went to Frankfurt, Germany 13 years ago, at the subway station, I saw a somewhat special automatic ticket vending machine. I entered the "validity period" of my subway ticket by myself, and after purchasing it, I walked through the crowded crowd. However, I vaguely felt that I had forgotten something, until I took several subway stops before suddenly realizing that I had forgotten to check my ticket. Why did I come in without checking your ticket? In China, every subway has to check tickets and enter the station through a gate. However, there are no turnstiles here and no ticket inspectors have been seen. At the destination station, there are still no turnstiles or ticket inspectors. All passengers are heading out without any obstacles. Later on, I found out that subway stations in Germany are fully open. There are no gates, no electronic ticket check gates, and no manual ticket checks. In the bustling subway stations, there is not even a fence. The reason for doing this is because we believe in the goodwill of everyone and believe that you will consciously and truthfully purchase tickets. By relying on this method of "believing in the goodwill of the public and randomly checking the malice of the niche", the cost of public transportation is reduced. Behind the adherence to "rules" lies the spirit of contract, the essence of this story, which is to use honesty to reduce transaction costs. Both transactions between customers and hydraulic manifold manufacturers, as well as transactions between hydraulic manifold manufacturers, require overcoming the costs of "information asymmetry" and "lack of credit transmission". If you want to make money, you need to first help customers save money. Assuming a subway station spends 100,000 yuan annually on turnstiles and ticket inspectors. Assuming that hydraulic manifold manufacturer AAK can complete the "ticket inspection" at a cost of only 50,000 yuan. So AAK can say: just 60,000 yuan, I'll take care of it. The extra 10,000 yuan is the money that can be earned. The missing 40,000 yuan is the money saved for the customer. Of course, the reality will be much more complex than this simple math problem. However, hydraulic manifold manufacturers must have this logic, as long as you can reduce transaction costs, you will almost certainly make money from it. In China's manufacturing industry, whether you are a hydraulic manifold manufacturer or not, the era of good people making money is coming. This good person refers to an honest person. More and more stories are proving to us that people who are honest, trustworthy, abide by contracts, and adhere to their values can survive, and even live well. If there is any dividend in today's business world, I think it must be a value dividend. Hydraulic manifold manufacturer AAK has been constantly strengthening its business brain and adhering to an honest heart. Hydraulic manifold manufacturer AAK, with brain, heart, and integrity.
