技术参数 Specifications |
|
当P口压力达到设定压力后，先导阀芯首先被打开，由此产生的 压差使得主阀芯打开，P到T实现溢流。该类型的阀反向可以承受 一定的背压,启闭率较高，适用于高压力、大流量的液压系统 When the pressure at "P" reaches the valve setting ,the pilotspool starts to open , Next the main spool opening because of the pressure drop between inside and outside of main spool,Realize overflow from P to T.This type of valve can withstand a certain amount of back pressure,has high opening and closing rate Suitable for the hydraulic system of high pressure and large flow.
