Erik compared more than 20 hydraulic pilot pressure control valve factories. No manufacturer can do the hydraulic pilot operated pressure control valves which can be used under high pressure above 450bar for more than one year. AAK hydraulic pilot operated pressure control valve passes the test at one time, and there is no abnormality after one year of use.
Erik is from a German hydraulic equipment manufacturer. In the first half of last year, the company needed to purchase a special hydraulic pilot operated pressure control valve with a working pressure of more than 450 bar, a service life of more than one year and a durability of more than 2 million times. The boss realized that it was some difficult to purchase the hydraulic pilot operated pressure control valve this time, and asked Erik and his colleague to purchase at the same time. Whoever successfully purchased the hydraulic pilot operated pressure control valve first will be promoted and raised. Erik is full of energy and keeps looking for hydraulic pilot operated pressure control valve factories online and offline. He contacted more than 20 new suppliers, including AAK hydraulic valve.
Most of the hydraulic pilot operated pressure control valve manufacturers replied that they need to be customized from the beginning of materials, and it takes 25 days to sample this special hydraulic pilot operated pressure control valve. Erik chose two factories to test the samples. A month later, Erik received the samples and asked the engineer to test them. The results failed, but the hydraulic pilot operated pressure control valve obtained by his colleague passed the first test, which made Erik very depressed. Fortunately, this is just in the test stage, the final effect depends on the test results of the hydraulic pilot operated pressure control valve one year later. Erik contacted AAK for the second time. He clearly informed that the samples of hydraulic pilot operated pressure control valves he selected in the first round failed. For the first time, he did not choose AAK because AAK needed 35 days. This time, he only asked AAK to make samples. Whether he can win or not, he can only count on AAK. Because the material selection and internal test of hydraulic pilot operated pressure control valves need time, Erik also understands the difficulties of making the samples. After 35 days, AAK sent 6 samples of hydraulic pilot operated pressure control valves.
Last week, almost a year after the hydraulic pilot operated pressure control valve samples were sent, Erik sent an email to inform that AAK hydraulic pilot operated pressure control valve was the only sample that passed 2 million tests, and there was no abnormality after one year of use. Although his colleague's sample passed the early test, it could not withstand the high pressure above 450 bar for enough time, it leaked in less than a year.
