Cliff is a purchaser of a hydraulic valve company in the United States. He began to contact the domestic hydraulic valve industry in China a few years ago and looked for new hydraulic valve suppliers everywhere. He didn't know much about the status of China domestic hydraulic valve industry and often ran up against a stone wall. A few months ago, he purchased a hydraulic diverter valve in Ningbo, the hometown of hydraulic valves. He encountered problems and could not guarantee the delivery date. It was a trial order of hydraulic diverter valve for their company's major customer. This customer is one of the world's top 500 enterprises. If the delivery date couldn’t be guaranteed, the boss must be mad. After the communication between his boss and the customer, the customer required that the remaining 50% of the hydraulic diverter valves must be delivered within 40 days, otherwise, the order would be cancelled and all future hydraulic valve orders will not be placed neither. Cliff took this as a chance to prove himself. He spent a week constantly looking for new hydraulic diverter valve manufacturers, sending emails and making phone calls. With the situation of his last hydraulic valve manufacturer, he found that nearly most of the hydraulic valve manufacturers had low awareness of production efficiency. No matter whether the time given by the customer is enough for production or not, they just accepted the orders first. If the customer is urgent in need of goods, nearly 90% of the hydraulic valve manufacturers will choose outsourcing processing. The same batch of shipment will come from different hydraulic valve processing places, and the quality of the hydraulic valves is uneven. Cliff's other hydraulic valve suppliers in Ningbo suggested him to see if AAK HYDRAULIC VALVE has time to catch up the delivery for these hydraulic diverter valves. After knowing about the situation, I suggested that he sent us 3 samples from the shipment of the hydraulic diverter valves, as well as the drawings, detailed information and process parameters etc, and then we can check if AAK can match the quality consistent and deliver the goods in time. The AAK technical team had formed the production process and operation instructions for each process for this hydraulic diverter valve order to clean up the mess, to ensure that the production can be completed with the time frame given to Cliff. Cliff was glad that we AAK HYDRAULIC VALVE could solve this problem, and wanted to know more about how we guaranteed the delivery date. I told him that there was an old Chinese saying that if you want a horse to run fast, you must let the horse eat well. Similarly, in the production of hydraulic valves, if you want to produce fast, you must not only have good equipment, but also special equipment. AAK HYDRAULIC VALVE has many high- precision imported CNC lathes and honing machines, as well as many small AAK designed fixtures and assembled special processing equipment. Each equipment has operation instructions. The production efficiency is 30% higher than that of its peers. Besides, AAK never cheat makes small tricks and has a correct production attitude. Our production line operates 24 hours, and the hydraulic valve technicians take two shifts off. Each process has strict operation standards, and the output of hydraulic diverter valve is 30% higher than that of its peers. Because of the importance of the delivery date of this hydraulic diverter valve order, during the production process of the hydraulic diverter valve, Cliff asked us to report the production progress by video every day after work, for fear that we would delay the shipment like the last hydraulic valve manufacturer. After 25 days, the mass production of hydraulic diverter valve was completed 10 days in advance. Cliff was happy to report to his boss. The customer was also surprised to learn that the delivery was early. Cliff finally put down his heart that had been suppressed for more than 30 days. AAK HYDRAULIC VALVE never makes small tricks, and the world's top 500 enterprises are also purchasing. Do you still have any concerns? https://www.aakindustry.com/

Osborne, from Iran, sent us a PO for 500 hydraulic cartridge relief valves today. I was not surprised by this repeat order, because at the time of inquiry, he said that as long as the quality was stable, he would repeat the order twice a year. In the second half of last year, their hydraulic pump needed hydraulic cartridge relief valve. He tried samples from 2 overseas hydraulic cartridge relief valve manufacturers, but the buffering function of the hydraulic cartridge relief valve was ordinary, which affected the operation of the equipment. Osborne contacted other cartridge valve manufacturers, but failed. I also don't know how Osborne found AAK hydraulic cartridge valve. AAK had no customers in Iran before. He left a message on the AAK website: please provide me your address, I would send you a sample to copy, and the buffering function of the hydraulic cartridge relief valve must be met. After receiving his hydraulic cartridge relief valve sample, according to his hydraulic system schematic diagram, and the video of equipment commissioning, after discussion of AAK engineers, a plan was worked out. After 45 days, AAK sent 5 samples of hydraulic cartridge relief valve. 2 weeks later, Osborne sent us an email to inform that the buffer function of AAK hydraulic cartridge relief valve met their equipment requirements. The first order of 500 hydraulic cartridge relief valves was also attached. After confirming the delivery date, the full payment was made the next day. The Iranian customer was so refreshing and efficient, which is out of my expectation. The two-stage buffer of AAK hydraulic cartridge relief valve can eliminate the pressure pulse of the hydraulic system and improve the service life of the equipment by at least 20%. The optimized hydraulic cartridge relief valve, when the pressure at the oil inlet reaches the first or second pressure, the two buffer pistons can act successively to realize the opening or closing of the hydraulic cartridge relief valve, absorb the pressure pulse at the oil inlet, and eliminate the system pressure impact. Here is the structure innovation of the hydraulic cartridge relief valve that AAK works out: 1. A sliding valve spool is arranged in the valve body cavity of the hydraulic cartridge relief valve. The left end of the valve rod is sleeved with a two- stage buffer piston, and the valve rod is equipped with a compression spring. One end of the compression spring is matched with the valve spool, and the other end is connected with the secondary buffer piston, and the sliding rod of the secondary buffer piston is set with the primary buffer piston. 2. The left port of the valve body is equipped with a plug, which forms a two- stage buffer cavity between the plug and the two-stage buffer piston. The two- stage buffer cavity is connected with the oil inlet through the two-stage buffer orifice and the valve spool orifice. 3. The outer peripheral surface of the valve spool head and the peripheral surface of the valve stem cavity are in sliding coordination. The front end is equipped with a cone sealing head. The valve body oil drain port is connected with the sealing cavity where the compression spring is located, and the oil outlet is connected with the cavity where the cone sealing head is located. AAK hydraulic cartridge relief valve made in China, 2-stage buffering function, equipment life increased by 20%, you can also try it! https://www.aakindustry.com/info-detail/ca , rtridge-relief-valves-aak516

Cleveland is from a hydraulic equipment company in Mexico. He has purchased hydraulic valves in Ningbo for 3 years. We have communications for two times. He is confident, but the hydraulic cartridge relief valves he purchased last time stumped him. At the end of last year, their customer customized a hydraulic paper cutter, which requires the use of a hydraulic cartridge relief valve. The engineer asked Cleveland to purchase SUN hydraulic cartridge relief valve standard parts, and the equipment commissioning was smooth. The customer was satisfied and placed the first batch of orders. Cleveland placed the order with a hydraulic cartridge valve manufacturer in Ningbo. 6 months after the equipment was sold, the customer complained that the stability of the equipment was not as good as the prototype. After checking, it was found that the hydraulic cartridge relief valve was leaking, and the standard deviation of valve hole accuracy was only 70% of SUN's. Cleveland contacted SUN, but SUN did not have enough inventory and needed a long lead time for production. The boss was not satisfied and requested to purchase the hydraulic cartridge relief valves that benchmarking SUN. Cleveland was worried. Cleveland contacted me and told me the dilemma he encountered in purchasing hydraulic cartridge relief valves. He knew that SUN was a loyal customer of AAK Hydraulic Valves for 3 consecutive years and needed my help. My engineer told me that as long as the heat treatment of steel is in place, the standard deviation of AAK processing accuracy can completely benchmark SUN, so that I have a good idea. No comparison, no harm. I deliberately told Cleveland that AAK was only 80% confident. In order not to delay after-sales service, it was recommended for him to find another two hydraulic relief valve manufacturers that he most recognized, that is, three manufacturers made samples at the same time. If AAK sample fails, the sample cost will be returned. 2 months later, Cleveland sent an email and advised that the standard deviation of the valve hole accuracy of the 3 hydraulic relief valve manufacturers was out. The test data showed that only the standard deviation of AAK was benchmarked with SUN hydraulic cartridge relief valves. I replied that the essence of manufacturing quality is standard deviation. This is why SUN has selected AAK hydraulic valves for 3 consecutive years, and they focus on the standard deviation. Cleveland's trust in AAK was thus opened. His boss was very satisfied with the price of AAK hydraulic cartridge relief valve, which was 30% cheaper than SUN. AAK hydraulic cartridge relief valve, the standard deviation of valve hole accuracy, benchmarked with SUN, is the result of comparison and also a fact. 1. In terms of material, the valve spool of this hydraulic cartridge relief valve is made of German 20CrNi2MoV bearing steel, and the heat treatment process of "secondary quenching+cryogenic treatment+low temperature tempering" is adopted. The micro hardness is 237-247 HV, and the wear resistance is more than 3 times that of similar steel. 2. On the equipment, the valve hole of hydraulic cartridge relief valve is finished with Swiss high-precision honing machine, equipped with diamond oilstone, which is completely ground without trace. The valve hole accuracy can be within 2μm, the surface roughness is Ra0.2-0.3. 3. In terms of detection, German Diatest small micropore diameter measuring instrument is used, the minimum measurement accuracy can reach 0.1μm, and the valves are 100% full inspected. AAK hydraulic cartridge relief valve, benchmarking SUN, and saving cost for 30%, you can also try a small order! https://www.aakindustry.com/info-det , ail/hydraulic-cartridge-relief-valves- aak385

At the beginning of September this year, an IP from Brazil left a message on the website of hydraulic cartridge valve manufacturer AAK: Can you deliver 300 pcs of hydraulic cartridge valves equivalent to HydraForce RV10-22 in 25 days? I checked our inventory and there are still 110 pcs of RV10-22 in stock. Based on this calculation, there is still time. But the CITIZEN Cincom lathe from Japan is still busy in production and cannot be used to produce hydraulic cartridge valve RV10-22. I replied to Rikard: Time is a bit tight for us. We suggest that you can check with other hydraulic cartridge valve manufacturers first. 3 days later, Rikard's email arrived again: Can AAK deliver the RV10-22 hydraulic cartridge valve within 30 days? After communication, we learned that Rikard had checked with more than 10 hydraulic cartridge valve manufacturers, all of which needs more than 40 days. Currently, most hydraulic cartridge valve manufacturers are in peak production season. Without some inventory and efficient equipment, hydraulic cartridge valve manufacturers would not dare to take on this order. I felt Rikard's urgency.   The workshop master told me that RV10-22 can be processed on the CITIZEN CINCOM lathe in 3 days. If there are no other old customers who urgently need RV10-22, it should be possible to complete the delivery of 300 pcs of RV10-22 hydraulic cartridge valves within 25 days. I replied to Rikard that there should be no problem to finish within 30 days. If everything goes smoothly, perhaps we can deliver it a few days earlier. 25 days later, hydraulic cartridge valve manufacturer AAK successfully shipped 300 pcs of RV10-22, and Rikard is very grateful. I told Rikard that the RV10-22 provided by hydraulic cartridge valve manufacturer AAK not only has a short delivery time, but also has stable manufacturing quality.   The automatic CNC lathe is the most basic equipment for every hydraulic cartridge valve manufacturer, but most hydraulic cartridge valve manufacturers use the ones made in China or Taiwan. The CITIZEN CNC lathe from Japan was mainly used for precision machining of military equipment in the early stage, with advantages in processing efficiency and accuracy. It uses dual axis arranged cutting tools, which can be equipped with 14 knives at the same time, and can complete all composite processing such as turning, milling, boring, and so on at once. AAK has also upgraded its online detection function, which enables in situ detection and accuracy control of key data during the machining process. Especially the clamping process was deeply loved by the experienced technicians of hydraulic cartridge valve manufacturer AAK. We also equipped an automatic feeding device to achieve fully automated production of a single machine tool, avoiding human error. Reducing the number of clamping times, improving production efficiency, and ensuring accuracy, there is no hydraulic cartridge valve manufacturer that does not like it. Hydraulic cartridge valve manufacturer AAK, has advantages in production efficiency compared to other hydraulic cartridge valve manufacturers in China: 1. AAK adopts equipment from the Japanese military industry and also upgrades local functions. I don't know which other hydraulic cartridge valve manufacturers in Ningbo have these actions. 2. The manufacturing quality of hydraulic cartridge valve manufacturer AAK is equivalent to HydraForce and stable. AAK dares to purchase various raw materials in bulk. 3. The fully automated production of a single machine tool has a processing efficiency 40% higher than most hydraulic cartridge valve manufacturers in China. Hydraulic cartridge valve manufacturer AAK, with fast production and 3 major guarantees, you can also try it out!

Last week, on a business trip to Shanghai, a customer of integrated hydraulic cartridge valves invited me to discuss the development of an integrated hydraulic cartridge valve. They had established an office in Shanghai for 6 years. A very strange customer of integrated hydraulic cartridge valves, they never came to AAK integrated hydraulic cartridge valve factory. Every time when necessary, they asked me to go to their Shanghai office. Although it only takes 3.5 hours to drive from Ningbo to his Shanghai office, I still enjoy taking the high-speed rail. It's not only easy, but I can also meet different people in the carriage and encounter some interesting things. As soon as I sat down, I saw the passengers in the front two rows struggling to put their luggage on the rack. I could understand his difficulties and awkwardness and was willing to help. Although none of the passengers around him helped him, I quickly got up and walked over, and we put his luggage together. After returning to my seat, the word 'empathy' came to my mind. Empathy not only includes being able to understand someone else's emotions, but also the desire to help them alleviate their pain. In other words, even if you don't help in the end, your thoughts should be 'I sympathize with you and hope to help'. But if you only understand his difficulties and don't want to care, then it's not empathy. In fact, in the business of integrated hydraulic cartridge valves, empathy is also indispensable. When you encounter a sympathetic customer or supplier of integrated hydraulic cartridge valves, it is easy to reach a consensus, not only saving time, but also taking care of emotions. A few days ago, while pondering a book on brain science, it mentioned that the ability of human empathy is generated by the cooperation of ten different brain regions, collectively known as the "empathy circuit". This circuit determines physiologically how much empathy each of us can generate. The reason why a person behaves cruelly is because the empathy circuit has malfunctioned. Overall, those with strong empathy have a higher frequency of connecting with the world, and human life is not just about "surviving oneself". Everyone has their own special values for people and things, and there is a deep connection between people. This cannot be separated from our "empathy". Those who are called villains, or those who are difficult to understand, are in this state where their empathy is relatively weak. What does it mean without empathy? It means that one cannot imagine how the other person feels, what one has done, what impression they have left, or even how to communicate with others. Not only that, they never even thought that others have their own perspective on problems. In this situation, they will completely ignore the thoughts and feelings of others, only care about what they want to do, and firmly believe that their ideas are 100% correct; If someone disagrees with them, they will think that the other person is either wrong or stupid. I am most afraid of working with people without empathy. Some integrated hydraulic valve customers, without empathy, always believe that having orders is God. Integrated hydraulic cartridge valve engineers, without empathy, always think that the other party is stupid. Integrated hydraulic cartridge valve suppliers, without empathy, always think that the customer does not understand. In life, regardless of whether the people around me are willing to help those in need, I can understand their emotions and the desire to help them alleviate their pain. In work, regardless of whether the colleagues of integrated hydraulic cartridge valves have empathy or not, AAK can understand customers' emotions and have the desire to help them not waste time or step into pitfalls. AAK HYDRAULIC VALVES (603) 2023-06-11 https://www.aakindustry.com/info , -detail/hydraulic-cartridge-valve-supplier- aak , 603

Nearly 90% of the hydraulic cartridge valve manufacturers in Ningbo can not achieve the filtration accuracy as high as 10 Microns. But AAK is 1 of the less than 10% hydraulic cartridge valve manufacturers with a filtering accuracy up to 10 Microns. Dylan came to AAK HYDRAULIC VALVE with a very special two position two-way hydraulic cartridge valve. I knew he should have encountered a problem. For this special hydraulic cartridge valve, the filtration accuracy of 10 Microns was the minimum requirement. Dylan consulted the existing cooperated hydraulic cartridge valve manufacturers, but none of them could meet the requirement. Most hydraulic cartridge valve manufacturers said that the filtering accuracy of 25 Microns is 100% no problem. Only 1 hydraulic cartridge valve manufacturer gave feedback and was 70% sure that the filtering accuracy could reach 10 Microns. Dylan directly asked me, is it really difficult for these hydraulic cartridge valve manufacturers in Ningbo to achieve the filtering accuracy of 10 microns? How can so many hydraulic cartridge valve manufacturers have said that they can only achieve the filtering accuracy of 25 Microns? I could understand his helplessness and confusion. This is because that the conventional hydraulic cartridge valve manufacturers produce hydraulic valves according to domestic hydraulic standards in China. Not only 1 or 2, but nearly 90% of hydraulic cartridge valve manufacturers, can only able to get the filter element aperture reaches 25μm. We AAK HYDRAULIC VALVE also used conventional filters at the beginning, and the filtration accuracy was also based on domestic standards. 3 years ago, a German hydraulic valve customer requested the accuracy requirement of 10 Microns, which was not only a stimulus but also a challenge for us. After more than 2 months of adjusting, we improved the process on the small sample, and adjusted the equipment parameters until it was configured to a high-precision filter and cooperated with AAK special hydraulic oil, so that the filtration accuracy of particles in the hydraulic oil could be controlled to 10μm. 1 year later, some hydraulic cartridge valve manufacturers learned that AAK had upgraded with high-precision filters and followed suit. However, due to technical constraints, many hydraulic cartridge valve manufacturers still failed to meet the standard. Under the same working conditions, if the hydraulic cartridge valves from these hydraulic cartridge valve manufacturers have a service life of 2 years, the service life of AAK hydraulic cartridge valves can be extended to 3-4 years. Dylan was surprised that we had mass produced hydraulic cartridge valves with filtration accuracy up to 10 Microns 3 years ago, but only 1 of his current hydraulic cartridge valve manufacturers could do it, and with only 70% sure. Dylan took out the drawings and asked us to send samples of this special hydraulic cartridge valve within 20 days. AAK HYDRAULIC VALVE, always has high requirements on precision. If you need to find a high-precision hydraulic cartridge valve manufacturer, click AAK HYDRAULIC VALVE website: www.aakindustry.com. AAK is your trusted hydraulic cartridge valve manufacturer. You can also try a small order. https://www.aakindustry.com/

The hydraulic directional valves produced by AAK adopts its own proprietary quenching and tempering heat treatment process, which can greatly improve the strength of the hydraulic directional valve, avoid deformation and wear of the hydraulic directional valve in the long-term use process, and significantly increase the service life. Perhaps there is no second comparable manufacturer in Ningbo like this. At most, 10% of the domestic hydraulic valve peers can compete. In order to win orders, 50% of the hydraulic valve manufacturers do not do any heat treatment to the materials for the hydraulic parts. Although some hydraulic valve manufacturers insist on heat treatment, they can only be outsourced processing due to without equipment. There are also 20% of hydraulic valve manufacturers, who do not have a fixed outsourced processing place, so it is impossible to ensure the heat treatment quality, not to mention the stability. Due to these common problems in the hydraulic valve industry, the hydraulic valve will show many problems after being used for a period of time, such as product deformation and wear. Once the hydraulic valve is deformed, it will easily to be blocked and the service life of the hydraulic valve will be greatly shorten. 5 months ago, Mike, a hydraulic valve customer in the United States, came to me. He had been confused, since 2019, there have been continuous customer complaints about the hydraulic directional valve he purchased. All the complaints are that after the hydraulic directional valve has been used for a period of time, some hydraulic directional valves are deformed and some hydraulic directional valves are worn quickly. Obviously, there is a problem with the heat treatment of the materials used in the hydraulic directional valve. Since 2019, due to the environmental protection policy, the domestic heat treatment plants have been vigorously rectified, and there are much fewer processing places. 50% of the hydraulic valve manufacturers do not have a place to do heat treatment to the raw materials. Even if heat treatment is done, 20% of the hydraulic valve manufacturers have to change the processing places for each external processing. I sent him several samples of AAK hydraulic directional valve and told him that the material hardness of our hydraulic directional valve has not changed, which always can reach about 50-55HRC or higher, and there is no problem with the special requirement of 65HRC. He didn't know that the service life of hydraulic valve is our hard index. 3 months ago, Mike issued a test order for the hydraulic directional valve. Each different part of the hydraulic directional valve is marked with different hardness requirements. He also wants to know how AAK ensures the service life of the hydraulic directional valve. To get a long service life of hydraulic directional valve, heat treatment is the first and most critical step. In order to do a good job in heat treatment, AAK has held a heat treatment factory for 10 years. The quenching and tempering heat treatment of hydraulic valve materials is sensitive to temperature. If the temperature is too low, hardness is not enough and easy to deform. On the contrary, it will lead to cracking. Only our proprietary heat treatment process can accurately grasp the appropriate temperature under the operation of a master with more than 6 years of experience. AAK can also select the corresponding heat treatment process and determine the temperature range according to the different working conditions of the hydraulic valve to ensure the service life of the hydraulic valve. AAK hydraulic directional valve has a service life of more than 90% of its peers, you can also have a small try. https://www.aakindustry.com/

Uberto is from a hydraulic equipment company in Mexico and has been engaged in the procurement of hydraulic components for 2 years. At the end of last year, their customer customized a hydraulic power unit, and the hydraulic manifold of it was made by a local hydraulic manifold manufacturer. The commissioning of the equipment was smooth, and the customer was also satisfied, but the price of the equipment was more than 15% higher than that of similar products in the market. The company requested to optimize the hydraulic manifold to reduce the cost, but the original hydraulic manifold manufacturer has no idea. Uberto found AAK website on google. According to the background trace, he stayed for more than 10 minutes and left us a message: Can AAK optimize hydraulic manifold to reduce costs? After communication, we learned that the customer disliked the high price of their equipment. According to the schematic diagram of the hydraulic system provided by him and the original hydraulic manifold drawing, after discussion, AAK technical team proposed an optimization scheme, which is to form a combined hydraulic manifold, reduce the installation difficulty and cost. When Uberto's engineers learned that AAK had an optimized hydraulic manifold scheme, and that the cost would be reduced by 30%, they expressed doubts, then there was no further news. 2 weeks later, Uberto suddenly requested AAK to make samples for the hydraulic manifold and paid the development cost. After 50 days, AAK sent 3 hydraulic manifold samples. Last week, Ubertor emailed that the hydraulic power unit with AAK hydraulic manifold had been installed on the equipment and had been tracked for 4 weeks. The function and stability of the hydraulic power unit is the same as the original hydraulic manifold. Their customer decided to purchase their hydraulic power units. The boss was very satisfied and their engineers were also impressed. The combined hydraulic manifold optimized by AAK is a modular, configurable and open hydraulic manifold. It abandons the traditional mode of using "single element" combined circuit, avoids overlapping functions and structures, and reduces control valves, which is the key to significantly reduce costs. 1. The four-way hydraulic manifold control system is composed of pilot control valve group, 4 two-way cartridge valve control components, manifold blocks and connectors. It has 4 main channels, several pilot control channels, and 2 external mounting surfaces, which greatly reduces components. This is a technical activity. 2. The top of the hydraulic manifold is provided with a boss, which is a boss type step surface composed of the boss and 2 parallel finishing planes. The mounting surface of the convex part of the boss is installed with 2 groups of pilot control valve groups, and the mounting surface of the plane parallel to the boss plane is installed with a two-way cartridge valve. 3. The left and right sides of the hydraulic manifold are used to connect the high pressure input port and low pressure output port of the main channel as well as the pilot control channel, and the rear side is used as the connection port of the high pressure output port of the main channel. The installation of components is convenient and fast.
