A few days ago, the development department of hydraulic manifold manufacturer AAK received a financial reimbursement document for me to sign. The rework cost for a set of hydraulic manifold is over 20,000 RMB. The explanation from the development department was that the client's development time frame was quite tight. As soon as the first version of the drawings arrived, the sales department asked the development department to speed up the work. However, halfway through, the client provided the second version of the drawings, resulting in rework. But the customer does not accept this money, the reason being that the first version of the drawings did not have the signature of their engineers. Similar situations have occurred in other hydraulic manifold manufacturers before, but at no cost. The cost of rework was also compared to other hydraulic manifold manufacturers. Our sales team went ahead without customer confirmation, citing the short lead time. In order to cooperate with customers and improve their satisfaction, the result of such reckless actions was over 20,000 RMB without anyone paying for it. When I lead sales, I often demand that sales use 3 good performances to demand ourselves: first, our service should be good, second, the manufacturing quality of hydraulic manifold manufacturer AAK should be good, and third, to make customers say we are good. However, our sales blindly pursue customer satisfaction and blindly cater to it. Similar incidents may occur frequently in other hydraulic manifold manufacturers, but AAK's 3 good performances are built on the process. In fact, there are many customer demands that are fake or even incorrect. At this time, as a professional hydraulic manifold manufacturer, we must dare to correct them. If the hydraulic manifold manufacturer only follows the customer's ideas, either the service provided by the hydraulic manifold manufacturer is blindly followed, or the hydraulic manifold manufacturer itself is not professional. Essentially, hydraulic manifold manufacturers should be more professional than customers, which require us to be experts in marketing, at least half of an engineer's sales. The most basic principle for hydraulic manifold manufacturers, whether they are developing or producing standard parts, is that only after signing and confirming can the next step be implemented. If you don't follow the process and do it well, the customer may not appreciate you. If you do it poorly, no one will pay for the additional costs. Customer satisfaction refers to the actual gain of a customer divided by their expected value. Sometimes, reducing a customer's demands can actually improve their satisfaction. In the sales process, if hydraulic manifold manufacturers dare to refuse customers improper requirements, sometimes in this process, most customers are reasonable. For the development of this hydraulic manifold, the sales seem to want to provide customers with so-called value-added services, but the value-added that customers do not receive becomes a mutual consumption. Simply pursuing so-called satisfaction can lead to satisfaction. Sometimes, on the contrary, the hydraulic manifold manufacturer will do whatever the customer says and do whatever they say. Firstly, blindly doing so will not have a good effect. Secondly, the hydraulic manifold manufacturer cannot earn the respect of customers. Thirdly, customers may feel that hydraulic manifold manufacturers are not very professional. Fourthly, customers may feel that you, as a hydraulic manifold manufacturer, lack processes or rules, and may look down on you. Therefore, I often say that sales do not come from seeking, but from requirements, or customers come here in admiration of their reputation. Hydraulic manifold manufacturer AAK, restrains itself with 3 good performances, and attracts customers with professionalism.

This weekend, many parents in China are focusing on their children’s college entrance examination scores and choosing universities. In China, the students are in a rat race, and the parents are also in a rat race. Nowadays, it seems that the industry of integrated hydraulic cartridge valves is also in a rat race in China. But in my style, I need to understand why first, then start, and then move steadily, at an appropriate speed. Although the China integrated hydraulic cartridge valve manufacturers are in a rat race for price competition, I have increased material and processing costs, improved the quality of various elements of integrated hydraulic cartridge valves, extended the performance of integrated hydraulic cartridge valves, and strive to achieve higher cost-effectiveness of integrated hydraulic cartridge valves. British writer Oscar Wilde said: There are only two tragedies in life, the first one is not what I want; The second tragedy is getting what I want. How can getting something be considered a tragedy? Because after getting it, I found out there was a mistake, not what I really wanted. I see others pursuing it, and I thought I should pursue it too. After obtaining it, I realized that it wasn't what I wanted. Engaging in manufacturing is like crossing a bridge, where one can only move forward with one heart, cannot turn back, and there is no bypass. In China, it has become the obsession of this generation to have children attend a good university, even graduate school if possible. But why go to college? What is the use of taking this course? This question is rarely considered. Today, a colleague of an integrated hydraulic cartridge valve talked to me about his child's situation. His daughter is studying at a university in Shanghai, majoring in customs declaration. His meaning is, "Don't worry about her now, wait for her to go abroad and pursue a master's degree after graduation, and then she must come back to inherit my integrated hydraulic cartridge valve career. I was surprised to ask: The things your daughter learned are not closely related to your integrated hydraulic cartridge valve. Even if she graduates from high school and can start taking over the integrated hydraulic cartridge valve career, why waste this time? His answer is: always look good on face! In fact, when it comes to going to school, not only should children think clearly, but parents also need to understand: if others go to college, does it mean that your children also need to go to college? A few days ago, it was reported that a courier uncle worked as a courier for 15 years, sending his child to college. Eventually, after his son graduated from college, he inherited his father's business and became a courier boy. This kind of thing cannot be considered news at all, because it is becoming more and more common in real life. In this era where master's degrees are everywhere and doctoral degrees are abundant, my personal opinion is that there is no need to exchange money and youth for a dispensable degree. It should be the style of every parent to make career plans for their children, cultivate their professional skills, and make them self-sufficient. My children, if they can go to college, will be instructed to study history or philosophy. After graduation, they will first go to the workshop to tighten screws and work at the bottom level of integrated hydraulic cartridge valves for 3 years, and then engaged on the sales of integrated hydraulic cartridge valves. If you are not as powerful, if you want to get along well in society, you should take it step by step from the bottom. The sincerity of the strong inspires admiration in people. The sincerity of the weak makes people feel like you're a fool. In the integrated hydraulic cartridge valve industry, the same applies. Only when your manufacturing quality is strong can customers have admiration for you.

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.

At the beginning of this year, CATERPILLAR received an order from African customer for excavators with a delivery time of 2 months, which means that all accessories must be in place within 1 month, including 600 hydraulic cartridge valves. The production time for the factory is a little more than 2 weeks. The purchaser Peter sent the order information of the hydraulic cartridge valve to all the hydraulic valve manufacturers he contacted before at the first time. More than 20 hydraulic valve manufacturers said that they could not complete the order of the hydraulic cartridge valve in such a short time, and it would take at least 3 - 4 weeks. His supervisor was not satisfied with this delivery time and asked him to find a new hydraulic valve manufacturer. After the email was sent, there was basically no sound. Peter was very helpless and worried. Peter asked Mark for help. Mark emailed AAK HYDRAULIC VALVE to ask if AAK could produce 600 hydraulic cartridge valves in 2 weeks and CC Peter, and joking at the end of the email that if AAK HYDRAULIC VALVE could not complete the hydraulic cartridge valve order, then there is no need to waste time on looking for a new hydraulic valve manufacturer. According to the drawings they sent, AAK technical department found that this was very close to the hydraulic cartridge valve supplied to a Russian customer last year, so the time in the early stage of the production of the hydraulic cartridge valve was saved. After the price of the hydraulic cartridge valve was approved, the process data could be configured on the computer on the same day and the production could be carried out the next day. 2 weeks later, 600 hydraulic cartridge valves were delivered on time, which was the first of all the accessories purchased by Peter to arrive at the company's warehouse. Peter didn't expect that the hydraulic cartridge valve he was most worried about was the first to be completed. Peter appreciated the advice from Mark and was also surprised that AAK could complete this in 2 weeks, while his previous hydraulic valve suppliers needed 3-4 weeks. Mark told Peter: 1.AAK is his most trusted hydraulic valve manufacturer. AAK can surprise him every time when the hydraulic valve order is urgent. 2.AAK has a large amount of data storage and clear classification. For hydraulic valves with relevant data, they can use the most advanced UG / SOLIDWORK software and finite element analysis method to configure process data in 2 hours, which is 3-6 times faster than that of other suppliers. 3.AAK is equipped with advanced machine tools imported from Swiss, coupled with their own modified fixtures, the production speed is accelerated and man-made errors are avoided at the same time. After listening to the introduction from Mark, Peter realized that only a good hydraulic valve supplier can make his purchasing smooth. CATERPILLAR successfully completed this urgent order. The boss was very happy when he heard the news. For Peter, who was the first to complete the purchasing, the boss affirmed his purchasing ability and praised him at the meeting. Mark told me privately that Peter was very happy because his boss gave him a promotion because of his excellent performance this time. AAK hydraulic cartridge valve has reliable quality and guaranteed delivery date. We are a manufacturer good at and focused on hydraulic cartridge valves only. Welcome to have a small try! https://www.aakindustry.com/

Caltha is from Mexico and has been purchasing hydraulic valve blocks in Ningbo China for 5 years. AAK is also one of his suppliers of hydraulic valve blocks. At the beginning of this year, their old buyer left the company and Caltha began to be responsible for the procurement of hydraulic valve blocks. The first inquiry I received from Caltha was for hydraulic valve blocks. A week later, Caltha informed AAK that the price was 17% higher and she chose another hydraulic valve block manufacturer in China. Upon seeing this big price difference, I had to give up. 2 months later, Caltha emailed me asking if the hydraulic valve blocks quoted at the beginning of the year could be completed for 5 samples within 25 days. I felt Caltha's anxiety, and after communication, I learned that the hole accuracy of the hydraulic valve block produced by the original manufacturer was not up to standard. However, the manufacturer blamed some valve hole accuracy deviations on being normal, and using electric sealant could solve the leakage. Caltha didn't want to take any risks and came back to AAK I can understand Caltha's emotions, after all, their company is a loyal customer of AAK. Our technical team started to decompose the hydraulic valve block drawings immediately. Within 25 days, AAK sent 5 hydraulic valve block samples. 2 weeks later, Caltha informed AAK that their hydraulic manifold had been tested successfully. She asked me to wait for the batch order of hydraulic valve blocks. The processing of hydraulic valve block valve holes that the original manufacturer cannot handle mainly depends on the selection of equipment and the control of accuracy. The processing of this AAK hydraulic valve block adopts the Taikan Group Processing Center, which has 3 major advantages: 1. The machining is stable, and its spindle structure adopts high-quality mihanna cast iron, with stable movement. For the same batch of hydraulic valve blocks, using the same tool and processing program, the motion trajectory of the tool is the same, and its CNC program achieves computer control, which can avoid human error. Most hydraulic valve block manufacturers do not choose this equipment. 2. High precision. The valve hole accuracy is within 0.005mm, and the repeated positioning accuracy can reach 0.003mm, and precision correction and compensation can be carried out simultaneously using CNC software. 3. High production efficiency. The spindle speed can reach 24000 RPM, and it also has functions such as automatic speed change, automatic tool change, and other auxiliary operation automation. Compared to ordinary machine tools, the production efficiency is 3-4 times higher. AAK hydraulic valve block, fast processing, and guaranteed accuracy, you can also give it a try!

Bryson is a hydraulic customer from the UK. Recently, a batch of hydraulic cartridge valves he temporarily purchased were in trouble. Because the parameters from customer were not complete, he used the same model product recommended by the hydraulic valve manufacturer instead. During testing, the flow parameters were not equal. The rated flow of the hydraulic cartridge valve was smaller than the working flow and could not be used normally, which wasted more than 10 days and the delivery time was urgent. He contacted with more than 10 hydraulic valve manufacturers. For hydraulic cartridge valves of the same model, their rated flow setting is either smaller than the working flow or close to the working flow of the system. Bryson was very distressed that no hydraulic cartridge valve has a rated flow setting greater than the working flow. Bryson found AAK HYDRAULIC VALVE. From AAK website, he felt that AAK HYDRAULIC VALVE was a little different from other hydraulic valve manufacturers. With a try attitude, Bryson actively contacted us and sent us the product picture and product model of this hydraulic cartridge valve. He just emphasized that the rated flow must be greater than the working flow and asked us to recommend the hydraulic cartridge valve of the same model, there was no any parameter information. After careful comparison, AAK engineers sent pictures and drawings of a hydraulic cartridge valve of the same model. Bryson asked us to send the hydraulic cartridge valve samples as soon as possible. On the 3rd day after receiving the hydraulic cartridge valve sample, Bryson emailed to inform that the rated flow of AAK hydraulic cartridge valve can really meet the normal operation of their current hydraulic system. Bryson expressed his curiosity that the hydraulic cartridge valve model recommended by AAK is consistent with that recommended by other manufacturers. How can there be such a big difference in the rated flow setting? For the selection of flow specifications of hydraulic valves, the settings of each factory are different. If the rated flow of the valve is close to the working flow of the system, this situation is the most economical and cost- effective, and it is also the first choice of nearly 90% of hydraulic valve manufacturers. But there may be a problem, once the working flow in the hydraulic system exceeds the rated flow, it will cause hydraulic clamping and affect the hydraulic power. It will also have an adverse impact on the hydraulic system of the valve. To be safe, when all cartridge valves are produced, AAK will give priority to the maximum flow that may pass through the circuit where the hydraulic valve is located, and the setting of rated flow is greater than the maximum flow of operation, so as to ensure the normal operation of whole system, which is also the reason why most customers prefer AAK. After knowing this information, Bryson is more convinced that AAK HYDRAULIC VALVE is different from other hydraulic valve manufacturers. It has been more than 3 months since we shipped the last goods to Bryson. Today, 200 hydraulic cartridge valves are re-ordered. Bryson told me that since AAK hydraulic cartridge valve was used, there was no hydraulic clamping problem in the hydraulic system. Their sales increased by 30% compared with the same period. The boss was very satisfied with his procurement work. The rated flow setting of AAK hydraulic valve meets the flow requirements of each system. Welcome to try an order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-valves-aak130

Kadin is from Brazil. I know that he has purchased hydraulic cartridge valves from Ningbo for at least 2 years. The peers joked that his bargain just like cutting vegetables. But a batch of hydraulic pressure control cartridge valves made him suffer. The reason may be that the price was too low. In the second half of last year, they received feedback from customer that the excavator they sold, the stick and boom will fall a short distance after stop working. Their engineers judged that the load holding function of the hydraulic pressure control cartridge valve in the system was abnormal. The original manufacturer of the hydraulic pressure control cartridge valve said that it is too difficult to optimize the function due to its price. Kadin contacted other cartridge valve manufacturers and asked that the load holding function should be 100% guaranteed, and there was no result after a week. In this way, the original manufacturer did not care about the function of the hydraulic pressure control cartridge valve supplied, and the new manufacturers also ignored him. Kadin was in a hurry. Kadin sent me an email: Can AAK 100% ensure that the hydraulic pressure control cartridge valve can maintain its load? After several rounds of communication, I learned that he had trouble in purchasing hydraulic pressure control cartridge valves. According to the video of equipment abnormalities complained by his customer and the production drawings of hydraulic pressure control cartridge valve, I fed back AAK's plan. Kadin asked for samples. After 45 days, AAK sent 24 samples of hydraulic pressure control cartridge valves. 3 months later, Kadin emailed me that it was nearly 3 months since AAK hydraulic pressure control cartridge valve was used, the customer did not find that the stick and boom were falling. His boss planned to replace the original manufacturer's hydraulic pressure control cartridge valves with AAK’s. AAK 100% ensures that the hydraulic pressure control cartridge valve has load holding function, which depends on the structural innovation. During the load holding process, the conical valve spool and valve sleeve form a conical sealing structure under the pre-compression force of the return spring. This can effectively reduce the clearance leakage through the pilot spool spool and reduce the boom drift. 1. The hydraulic pressure control cartridge valve is equipped with a pilot sliding cone valve spool and a pilot oil passage. The valve body, valve sleeve and pilot spool valve spool cooperate with each other to form 6 chambers from left to right. There is a load oil circuit in the sixth chamber, which is connected with the fifth chamber through the first orifice and the second orifice. The fifth chamber is connected with the second chamber with the main valve body through the oil inlet hole. 2. The main valve body of the hydraulic pressure control cartridge valve has a one-way valve spool and a one-way valve spool spring chamber. The third chamber is connected with the spring chamber of the one-way valve spool through the throttling groove, and the spring chamber is connected with the second oil drain hole and oil drain passage. 3. The pilot control part provides the hydraulic pressure control cartridge valve with load holding relief pressure oil through the pilot oil passage, and the fourth chamber is connected with the oil drain passage through the first and second oil drain holes. When the load is maintained, a conical sealing structure is formed between the one-way valve spool and the main valve body. AAK hydraulic pressure control cartridge valve, 100% load holding function, is not only safe, you can also try it! https://www.aakindustry.com/info-detail , /pressure-control-cartridge-valves- aak523

When I opened the mailbox this morning, I saw a reorder for 500 pilot hydraulic relief valves from Jimmy. He mentioned that the pilot hydraulic relief valve designed by AAK had been used for 2 years and without any complaints. Jimmy is a purchaser of American company Vickers, responsible for the purchasing of hydraulic parts. 2 years ago, his company encountered a complaint from customer for a hydraulic pump. The customer complained that it screamed after being used for a period of time. After dissecting, their engineer found that there was a problem with the hydraulic relief valve in the hydraulic pump. The boss asked Jimmy to solve the problem as soon as possible. Jimmy sent the hydraulic relief valve back to the original supplier, but the supplier replied that the inspection result was good. Maybe the problem happened during installation. Jimmy’s engineers tested the samples by themselves and found that there was no problem with the hydraulic relief valve, but there was also no problem with the installation method and operation. Now Jimmy is depressed. The boss is pushing for status, but he has no clue. He contacted with several local hydraulic valve manufacturers in the United States, and they all replied that there was no problem on the hydraulic relief valve. One day, after browsing AAK website (www.aakindustry.com) in Google, Jimmy sent an email asking if AAK could help analyze the reason. We replied that it would be better for engineers to have video communication on site Jimmy decided to ask Vickers engineers to make a video with AAK engineers the next morning. After more than half an hour of observation, AAK engineers found that once the pressure oil at the inlet, outlet and control port of the hydraulic relief valve fluctuated, it would produce a scream. We got their original samples and drawings, as well as the working parameters of the hydraulic pump. After 15 days, AAK sent a sample of the pilot hydraulic relief valve. A week later, Jimmy e-mailed us that AAK hydraulic relief valve was installed and tested on site for 24 hours, and there was no scream. Jimmy wondered why there was no scream when AAK hydraulic relief valve was used. AAK engineers analyze the cause from the hydraulic impact. After the hydraulic pressure impacts the main valve spool in the hydraulic relief valve, the pressure oil converges through the check valve, resulting in fluid impact and fluctuation, causing the hydraulic relief valve to oscillate, resulting in the instability of the pressure oil at the outlet of the hydraulic pump. Because the pressure oil output by the pump itself has pulsation, the pressure oil output by the pump will fluctuate strongly and arouse the vibration of the hydraulic relief valve. For the natural frequencies of the two hydraulic relief valves are the same, it causes the resonance of the relief valve and the scream occurs. AAK engineers changed the design to replace the two hydraulic relief valves with the same pilot hydraulic relief valves, and set the corresponding overflow value according to the working conditions. The sample was made based on this process idea. After solving the problem that bothered Jimmy for half a year, he can finally confidently report to his boss. After listening, his boss also praised AAK hydraulic valves and hoped that AAK can produce 50 pilot hydraulic relief valves as soon as possible to solve the complaints from users first. With AAK unique designed pilot hydraulic relief valve, there has been no complaint about scream for two years. Jimmy doesn't want to find a second supplier anymore. AAK pilot hydraulic relief valve, the unique design of the remedy to the case, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak129

Most hydraulic manifold manufacturers in China do not produce hydraulic cartridge valves, and some even purchase manifold blocks externally. Recently, a listed company in China (with multiple types of hydraulic equipment) left a message on the website of hydraulic manifold manufacturer AAK: Can you produce 300 hydraulic manifolds within 30 days? I didn't reply as soon as I saw it was from the domestic market. The next day, the other party called directly. I replied to him: Sorry, AAK only focuses on foreign markets, and hung up the phone. Surprisingly, on the third day, the other party came to AAK factory directly. After communication, it was learned that a hydraulic manifold manufacturer in Ningbo recommended AAK to him. It turned out that the hydraulic manifold blocks he purchased from the original hydraulic manifold manufacturer had hidden problems, and more than half of them needed to be re produced. This batch of equipment was for Russian market, and ship date could not be delayed. He also knows that the hydraulic manifold manufacturer AAK is focused on the foreign market, and their equipment is also exported to the foreign market. He hopes that AAK can produce this order. Producing 300 hydraulic manifold blocks in 30 days, in addition to redraw work drawings, according to the conventional production layout, time will definitely not be enough. Moreover, the processing difficulty of this manifold is high, and the oil circuit is complex. There should be less than 3 hydraulic manifold manufacturers in Ningbo China that can handle this order. After 2 hours of communication, the other party said that within 30 days, the hydraulic manifold manufacturer AAK can produce as much as possible. Actually, it's not because AAK is conservative or not, but because AAK's vision is in the international market. Our efficient equipment serves our old customers in the international market. It's not too difficult to produce 300 hydraulic manifold blocks with over 20 days of full load production, as long as there is equipment that can process multiple hydraulic manifold blocks at the same time. Most hydraulic manifold manufacturers process manifold blocks one by one. But hydraulic manifold manufacturer AAK has a CNC from Taiwan that can process 8 manifold blocks simultaneously. Simply put, one equipment of AAK is equivalent to 8 equipment of other hydraulic manifold manufacturers. This video has been briefly filmed before, but the fixture of this equipment has flaws, and AAK is currently undergoing personalized customization and upgrading. The advantages of this CNC are high accuracy, a movement speed of up to 48 meters per minute, and equipped with 24 water jet drills. While cooling the cutting tools, it can also wash away chips and avoid residues. The ability to process 8 manifold blocks at the same time is the main reason why we bought this equipment. With one program debugging, we can complete the same surface processing of 8 hydraulic manifold blocks. Eight hydraulic manifold blocks are placed in the fixture and manually tightened, which poses a potential problem and requires experienced technicians to operate. Most operators are still unable to handle this manual process. Hydraulic manifold manufacturer AAK in Ningbo China, has a high production capacity of 1 day equals to 8 days of peers in the industry.

Martin, a purchaser of American company PowerTeam, sent an email last week saying that he saw on the Internet that AAK was a hydraulic valve supplier of some European hydraulic pump companies. He wanted to know whether the quality of AAK could match the quality of the hydraulic valve produced in the United States he was currently using. I directly answered that the quality of hydraulic valves in the United States should also be in different levels, you can have a small try and compare them with your hydraulic valves purchased in the United States. Martin frankly told about his current purchasing status. He needed to re- purchase a batch of hydraulic sequence valves for hydraulic pumps. After placing an order with the original manufacturer in the United States, the manufacturer told him that there were not enough labor for mass production at this moment. He had to wait for 3 months at least. The boss was not satisfied with his purchasing arrangement and asked him to find a new supplier of hydraulic sequence valve and complete production within 2 months. Martin is a little embarrassed because this hydraulic sequence valve has particularly high requirements for various accuracy. In the early stage of development 3 years ago, he contacted more than 20 hydraulic valve manufacturers, compared and tested the hydraulic sequence valves from them, and only the samples from the local hydraulic valve manufacturer in the United States met the requirements. Martin saw the information of AAK to found that it was actually the supplier of hydraulic pumps in Europe. After browsing AAK website (www.aakindustry.com), he felt that AAK hydraulic valve might become his supplier. According to the drawings and working conditions of his hydraulic sequence valve, we found that it does have high requirements for the accuracy of the hydraulic sequence valve. I told Martin that we need 15 days to make and test samples. After the samples of the hydraulic sequence valve pass the test, we will discuss the order at that time. 10 days after the hydraulic sequence valve sample was sent, Martin emailed AAK that the hydraulic sequence valve fully met the production requirements of the existing hydraulic pump. At the same time, the engineers of PowerTeam also applauded every detail of AAK hydraulic sequence valve sample, which was no worse than that of the American company. In particular, some core parameters, such as the matching surface roughness of AAK hydraulic sequence valve spool and valve hole, can reach Ra value of 0.1 ~ 0.2μm. The surface roughness Ra value of the outer circle of the valve spool is 0.1μm. The Ra value of the inner circular surface of the valve hole is 0.2μm. Some parameters are even higher than those of his original American manufacturer, including 100% burr removal. Martin was surprised how AAK hydraulic sequence valve achieve these? AAK hydraulic valve has two absolute advantages and has already surpassed its domestic counterparts. It is uncertain whether it has surpassed its American counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and independent fixtures upgraded and refitted by itself, eliminating human errors. 2.The independent professional R & D team cooperates with the unique R & D technology to realize the personalized customization demand of hydraulic valve accuracy, which can not be achieved by 95% of domestic peers. When Martin got the quotation of AAK hydraulic sequence valve, it was 23% cheaper than that produced locally in the United States, but the quality was no worse than that produced locally. AAK needed a lead time of 35 days for production, and the whole time was also in line with Martin's re-purchasing time schedule. After finalizing the whole order, Martin reported to the boss. The boss was very happy that AAK hydraulic sequence valve benchmarked the American quality, and also saved the purchasing cost. Martin told me that his boss asked him to send samples of previously purchased hydraulic valves to AAK for quotation. AAK hydraulic sequence valve keeps pace with American manufacturers. Not only the hydraulic sequence valve, our quality of hydraulic flow control valve also convinced a Germany customer.
