With O-ring that does not fall out of groove and wear, AAK Hydraulic check valve
:
Last week Logan said that he needs to order 1,000 hydraulic check valves at one time and asked me to hurry up to prepare materials. After reading this email, I felt very good. Logan comes from a Canadian hydraulic equipment company. Two years ago, he found AAK Hydraulic Valve on the Internet. The hydraulic elevator to be developed by their company needed to use special hydraulic check valves. He asked AAK to make 20 hydraulic check valve samples urgently according to his drawings, and promptly paid the development cost. According to the drawing, the O-ring of the hydraulic check valve is a little special, and each component needs to be customized. It took more than 2 months for AAK to successfully finish and send 20 hydraulic check valves. Strangely, after samples were sent, there was no news in 9 months until Logan's email last week.
Logan also frankly told us why we did not receive the feedback until now. It turned out that their company had selected 3 factories to test the samples of this hydraulic check valve. In the first test, the samples from all the 3 factories reached the standard, so they chose the cheapest one to place an order. Six months later, they knew the trouble was coming. The customer reported that the lift was unable to rise. After checking, it was found that the hydraulic check valve leaked and did not maintain pressure. The reason for the leakage was that the O-ring of the hydraulic check valve was out of the groove and worn.
Logan contacted the original hydraulic check valve manufacturer, and the manufacturer replied that the O-ring was a quick-wear part. If the customer used it frequently, the quick-were part needs to be replaced every 6 months, and the O-ring replacements can be provided free of charge. However, in such frequent after-sales, the sealing ring is a small amount of money, but the after-sales cost is the big trouble. Moreover, the customer may not accept it.
Logan checked the original archived samples again to verify the reliability of the O-ring of the hydraulic check valve, and found that the O-ring of AAK was different from that of other manufacturers. He also remembered that AAK was the latest one to deliver samples at that time. Their engineers compared and tested the O-ring of the hydraulic check valves again, and found that the O-ring of AAK was not only different in material, but also different in structure.
