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 valvesetting ,the pilotspool startsto open , Next themain spool opening because ofthe pressure dropbetweeninside and outside of main spool,Realizeoverflow from P to T.This typeof valve canwithstanda certain amount of back pressure,has high openingand closingrate Suitable for thehydraulic system of high pressure and largeflow.
