从China供应商批量进口Relief Valve Resistant To High Pressure

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.
