AAK Hydraulic Cartridge Pressure Relieving Valve has 2 advantages， Antonio has n

Antonio, from Mexico, began purchasing hydraulic cartridge valves from China 3 years ago. Last September, Antonio customized a hydraulic pilot operated pressure relieving valve in Ningbo for use in their newly developed hydraulic power unit. During equipment commissioning, it was found that the internal leakage of the hydraulic pilot operated pressure relieving valve was not up to standard and the opening and closing performance was not satisfactory. The original hydraulic pressure relieving valve manufacturer has revised the samples 3 times, but none of them can satisfy their engineers. Antonio was very upset.

Antonio saw the customer case of the hydraulic pressure relieving valve released by AAK in B2B, and left a message.

1. What is the minimum internal leakage of AAK hydraulic pilot operated pressure relieving valve?
2. What is the sealing effect of AAK hydraulic pilot operated pressure relieving valve?
3. What is the opening and closing performance of AAK hydraulic pilot operated pressure relieving valve?

I suspected that he was unsuccessful in testing hydraulic pressure relieving valve from other hydraulic cartridge valve manufacturer. After communication, it was learned that the original manufacturer had failed 3 times, which touched me. Perhaps the direction of optimization was wrong. According to the equipment abnormality video sent by him, combined with the hydraulic system and the original sample, AAK engineers found the problem and were 90% confident that the sample would be successful. After 45 days, AAK sent 8 samples of hydraulic pilot operated pressure relieving valves.

Last week, Antonio said that after installing AAK hydraulic pilot operated pressure relieving valve into their hydraulic unit, the operational lag was resolved. AAK hydraulic pilot operated pressure relieving valve has two major advantages: small internal leakage, good opening and closing characteristics, and the original hydraulic cartridge valve manufacturer can only be amazed.

1. The valve sleeve of the hydraulic pressure relieving valve has an outwardly inverted triangular clamp head at one end, and the adjusting sleeve catches the clamp head. The valve sleeve and the adjusting sleeve are fixedly connected together. There is a steel ball between the valve seat and the pilot valve spool, and there is a circular hole on the valve seat that communicates with the radial hole and can accommodate the steel ball. There is a blind hole on the pilot valve spool to accommodate the steel ball.
