Relief Valve Resistant To High Pressure Suppliers and Manufacturers

AAK hydraulic relief valve is resistant to high pressure and is not stuck. Ernst doesn't want to change the supplier any more Ernst is from a German hydraulic equipment company. He has been doing well in recent years, and his boss is optimistic about him. The hydraulic relief valves purchased this time has suffered a big setback. In the second half of last year, the hydraulic power unit sold by their company for less than 3 months was complained by customers. When the pressure of the hydraulic relief valve was adjusted to 450bar, the equipment idled. The engineer thought that it could be solved by changing the motor. As a result, after the equipment started for a while, the same situation happened again. The engineer checked each component, and it turned out that the spool of the hydraulic relief valve was stuck. After the boss knew about it, he asked Ernst to request the original hydraulic relief valve manufacturer to solve the problem and bear the motor cost twice. Per the manufacturer, the price of the hydraulic relief valve is too low this time. Under the high pressure of 450bar, it is difficult to avoid a few stuck occasionally, then there is no further news. Ernst had no choice but to find new hydraulic relief valve suppliers. Ernst contacted more than 10 factories and requested that the hydraulic relief valve be 100% free of jamming within 1 year under the high pressure of 450bar. Only two factories were willing to cooperate with the samples, and other manufacturers gave up directly. Ernst still seemed worried about wasting time. With the introduction of his friend Steven, who is our old customer, he contacted AAK hydraulic valve. Ernst asked us to make samples directly according to his hydraulic relief valve drawings and working conditions. The key of this hydraulic relief valve is how long the service life of the hydraulic relief valve is under 450bar high pressure? Actually, AAK has already mass produced hydraulic valves with similar requirements. Nine months later, Ernst informed by e-mail that the hydraulic relief valve from one factory had been on strike because of its stuck, and the other factory's, although still working, it was estimated to be less than 12 months. After 9 months of use, the parameters of AAK hydraulic relief valves are still stable and function normally. Ernst said that compared with more than 10 factories, AAK high-pressure hydraulic relief valve has the most stable performance and longest service life among all the manufacturers he knows. Ernst estimated that he would not need to change the hydraulic relief valve suppliers any more. AAK hydraulic relief valve has 3 advantages and has already surpassed its domestic counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and its own upgraded and refitted independent fixture, which eliminates human errors. The high-precision control of component processing is the key point to prevent jamming.

Description: To ensure safety, the drilling pump is equipped with safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope. The high pressure safety valve is forged by high quality structural alloy steel. As a kind of protection device and human safety device, it is generally installed on cementing devices, fracturing pump, high pressure operation piping, pressure vessel and devices under high pressure and high flow capacity. It controls elastic force of the valve seat by adjusting the nut on the top. Once the pumping pressure or piping pressure exceeds pre-established pressure value, safety valve opens automatically to release the pressure. When the pressure value reaches the normal value, valve rod will recover the position by spring and close the valve.

Jone is a hydraulic customer from the United States. His company has recently developed a hydraulic relief valve suitable for machines with high impact and high load. Because of the high requirements of working conditions, the steel used for the hydraulic relief valve has not been approved yet. They have been testing in the local hydraulic relief valve manufacturers in the United States for several weeks. Due to the high cost of proofing in the United States, they want to turn to Chinese hydraulic relief valve manufacturers for sampling and testing. Jone compared more than 10 hydraulic relief valve manufacturers and selected 3 to make samples. After receiving and testing the samples of hydraulic relief valves, none of them can meet the requirements of service conditions, and the test results are much worse than those of local manufacturers in the United States. Although these 3 hydraulic relief valve manufacturers changed the materials and improved the parameters, the toughness and plasticity of the steel still did not meet the working conditions, and Jone and his team were at a loss what to do. His friend Tom recommended him to contact AAK hydraulic valve for a try. Jone sent us an email with a try attitude. According to his hydraulic relief valve drawings and the working conditions with large impact force and high load, our engineers were not 100% sure, but were 90% sure, giving 2-3 weeks. Two weeks later, AAK successfully sent 6 hydraulic relief valve samples. On the 3rd day after Jone received the hydraulic relief valve samples, we received an email that the samples of hydraulic relief valve passed the performance test. AAK spent 2 weeks to try over 10 kinds of steels, and finally determined to replace 40Cr with 35CrMo steel. The high toughness and plasticity parameters of 35CrMo well match the working conditions of this hydraulic relief valve. At the same time, 35CrMo has high static strength, impact toughness and high fatigue limit, and the long-term working temperature can reach 500 . Jone was surprised that the samples of more than 10 hydraulic relief valve manufacturers in China were not successful. Even if the local manufacturers in the United States spent 4 weeks but still failed, how can AAK succeed in 2 weeks one time? The reason why AAK hydraulic relief valves can do what the domestic factories in the United States failed to do, because: 1. AAK has full-time material engineer who is specially responsible for material screening, comparison, testing and docking with the materials research institute. 2. Good materials also need good processing. The heat treatment method adopted by AAK for 35CrMo alloy steel is 845 annealing, 860 quenching (oil quenching) and 200 low-temperature tempering. After this special heat treatment, its hardness and wear resistance are increased by at least 50%.
