3 Advantages of AAK hydraulic cartridge relief valve, , a hydraulic customer from Bolivia, failed to purchase hydraulic cartridge relief valves from for the first time. has purchased hydraulic components from local hydraulic cartridge valve manufacturers in Bolivia for 3 years. He heard from his peers that the cost performance of purchasing from is better than that of Bolivian hydraulic valve manufacturers, so he began his overseas procurement trip. A hydraulic cartridge relief valve with rated pressure exceeding 30MPa, and the fit clearance between valve body and valve spool is required to be 0.006~0.01mm. successively tried samples with 3 hydraulic cartridge relief valve manufacturers in 70 days. The hydraulic cartridge relief valve samples had either internal and external leakage, blocked oil circuit, or even stuck. 3 times of proofing failed, which made helpless and even suspected that he was misled by his domestic peers. Richard noticed AAK on the B2B website and saw some tweets and customer cases to solve the problems of hydraulic cartridge valves, especially some big brands such as HydraForce and SUN Hydraulics, are also loyal customers of AAK for many years. He seemed to see hope and left a message to us: How much MPa can the rated pressure of the hydraulic cartridge relief valve with a clearance of 0.006~0.01mm between the valve body and the valve spool be? When I saw this message, I subconsciously felt that he had stumbled in the accuracy when purchasing this hydraulic cartridge relief valve, and he was inexperienced in choosing the hydraulic cartridge valve manufacturer. According to the problems of his hydraulic cartridge relief valve samples, AAK technical team determined that the problem was caused by burrs inside the hydraulic cartridge relief valve. However, the specific problem still depends on the sample analysis. I suggested Richard making samples directly to see the manufacturing quality of AAK hydraulic relief valves. Maybe that will change his view on China hydraulic cartridge valve manufacturers. After 30 days, AAK sent 10 samples of hydraulic cartridge relief valve. 6 months later, Richard emailed us that AAK hydraulic cartridge relief valves did not have the problems of "internal and external leakage, or blockage of the oil path or stagnation" that occurred in other hydraulic cartridge valve manufacturers, which also strengthened his confidence in purchasing from China hydraulic cartridge valve manufacturers. How to effectively avoid burrs of hydraulic cartridge relief valves? It is also a "thorn" that AAK has to remove since it was engaged in the R&D and manufacturing of hydraulic components. With 13 years of manufacturing experience, AAK can be sensitive to find problems and solve them. In the processing of hydraulic cartridge relief valves,

Some time ago, , from a Hydraulic Valve Company in UK, fell in a batch of hydraulic directional valves purchased in Ningbo. There had some email communication between HYDRAULIC VALVE and , but maybe the fate has not yet arrived, we did not cooperate until last month this year. Steven regained his confidence because he had suffered a waterloo and got back a key game here in . At the beginning of this year, a batch of hydraulic directional valves purchased by Steven in Ningbo were stuck and failed during the test run, resulting in the failure of the whole batch of equipment to start up and run. His customer asked UK company to solve it within 30 days, otherwise there will be a big claim. Steven informed the original hydraulic valve manufacturer of these conditions, but the manufacturer prevaricated that it was a problem caused during the assembly process and had no direct relationship with them. Steven also consulted other hydraulic valve manufacturers. They either replied that the hydraulic valve was not produced by them and could not give the corresponding strategy, or there was no reply. Steven received serious rebuff here and there, and feel stressed. When contacted HYDRAULIC VALVE, we were willing to cooperate with him to solve this problem because we felt his trust in HYDRAULIC VALVE. Through his email description, we were still not sure what the problem is, and asked him to send us samples. After HYDRAULIC VALVE received the hydraulic directional valve samples from Steven, we felt that the relative sliding between the middle valve column and the valve body was not smooth. When the whole hydraulic directional valve is disassembled, there are slight scratches on the column surface, the valve body hole has a negative tolerance, and the valve body column hole has plastic distortion. Further microscopic examination showed that the surface of the material was etched badly. It is certain that the original hydraulic valve manufacturer has problems in material selection and heat treatment of alloy steel. Then we informed Steven of the result in a report and attached our suggestions for this style of hydraulic directional valve. After receiving the report, Steven seemed to see hope and asked us to make 5 hydraulic directional valve samples for his customer to run successfully first. After knowing the working conditions of this hydraulic directional valve, we adjusted the material selection of alloy steel, and increased the overall hardness of the hydraulic directional valve by 30% on the original basis. week after Steven received the samples, he informed HYDRAULIC VALVE by e-mail that the hydraulic directional valve samples made by were started up smoothly as soon as they were tested on the machine. When the new delivery date and order quantity were confirmed by his customers, he was finally relieved.

In Google, enter the types of hydraulic valves, and you can get a series of information about the types of hydraulic valves. It looks like that each description about the types of hydraulic valves are all right. This makes Berge a very big headache. He transferred from the quality control department to the import department. He is a very studious buyer. Every time, when domestic hydraulic valve manufacturers in China receive his design drawings, they ask a lot of questions about the types of hydraulic valves. Berge asked me how to clearly understand the types of hydraulic valves expressed by hydraulic valve manufacturers and how AAK classifies the types of hydraulic valves. I gave him an example. If there are a pile of stools there with various shapes and materials, how should we classify them? Firstly divide the same kind of materials together, and then classify them for the second time to put different shapes together. This simple dichotomy is also suitable for the types of hydraulic valves. What is a hydraulic valve? It is a hydraulic element used to control liquid pressure, flow and direction in hydraulic transmission. Letâ??s classify the types of hydraulic valves for the first step: A. The types of hydraulic valves are divided into 3 categories according to their functions: directional control valve (such as one-way valve, reversing valve etc.), pressure control valve (such as relief valve, sequence valve, pressure reducing valve etc.), flow control valve (such as throttle valve, speed regulating valve etc.). B. According to the operation, the types of hydraulic valves are divided into manual valve, motorized valve, electric valve, hydraulic valve etc.. C. According to the control, the types of hydraulic valves are divided into Control valve, Cartridge valve and sandwich plate valve. D. According to the installation, the types of hydraulic valves are divided into threaded connection valve, plate connection valve, integrated connection valve, Superposition valve and cartridge valve Then, let is classify the types of hydraulic valves for the second step. From above A category, if according to the installation, you will get the sub-category of the types of hydraulic valves, for example, the threaded hydraulic pressure valve. Berge understood the dichotomy of the type of hydraulic valves immediately, especially dividing them by using stools as example, which is very practical. As soon as you listen and compare, you will understand, and can well understand the various questions about the types of hydraulic valves from different hydraulic valve manufacturers. In this way, the types of hydraulic valves are summarized from different angles. Combined with the dichotomy of the types of hydraulic valves, the types of hydraulic cartridge valves are basically clear, and they are interconnected and integrated. AAK HYDRAULIC VALVE can express any complex question about hydraulic valve to you with "analogy".

Kaden, a hydraulic valve purchaser from the United States, has been successfully purchasing hydraulic valves from China in recent years, and his boss also attaches great importance to him. Last month, at the original hydraulic valve manufacturer, he placed an order for a hydraulic valve block with multi-stage valve spool hole. The manufacturer confirmed that there was no problem and submitted the PPS of hydraulic valve block for 3 times, but the accuracy of valve spool hole was not approved every time. This made his customer very unhappy and thought it was a waste of his time. If the 4th hydraulic valve block sample still could not be approved, the order would have to be cancelled. The boss was also surprised and asked him to solve it within a time limit. Kaden felt unprecedented pressure. Kaden realized that the current hydraulic valve manufacturer must be replaced and contacted with no less than 10 hydraulic valve manufacturers. No factory has the ability to accept the order of this hydraulic valve block. Because the valve spool hole of this hydraulic valve block had a multi-stage structure, the accuracy was difficult to be controlled, the diameter tolerance of the valve spool hole of the hydraulic valve block was small, and there were many accuracy requirements such as coaxiality. Kaden was a little frustrated and seemed to have to give up. A hydraulic valve manufacturer in Ningbo told Kaden that the multi-stage valve spool hole must be processed with URMA reaming technology, and AAK hydraulic valve had this technology and could have a try. Kaden contacted us AAK hydraulic valve, directly indicating that he was introduced to us by a hydraulic valve factory, now he was in trouble with a special hydraulic valve block. He sent us the drawings and parameter requirements of the hydraulic valve block, and asked whether we were sure to be able to produce this hydraulic valve block. After analyzing the drawings, the technical team of AAK hydraulic valve told him that we would send the samples of hydraulic valve block directly to him for testing after 12 days. If the accuracy of hydraulic valve block met the requirements, we could produce it. Kaden requested that the PPS of the hydraulic valve block must be good so as not to completely disappoint his customer. On the 5th day after receiving the sample, he was very happy to inform us by email that after two tests by his company and his customer, AAK's hydraulic valve block met the requirements. He asked us to prepare materials and production can be started once other details are determined. AAK hydraulic valve URMA reaming technology adopts guide bar support to ensure correct tool position and rigorous cooling to ensure tool lubrication. Especially for multi-stage valve spool hole, or valve spool hole with small diameter, we have our own processing experience. This is rare in Ningbo hydraulic valve manufacturers.

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 owner 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 ~ 0.2�¼m. The surface roughness Ra value of the outer circle of the valve spool is 0.1m. The Ra value of the inner circular surface of the valve hole is 0.2m. Some parameters are even higher than those of his original American manufacturer, including 100% burr removal.
