阀的额定压力是通过调节弹簧力实现，当P口压力达到设定

压力后，阀被打开，P到T开始溢流;反方向，从T到P可以很

低的压力打开。该阀反应灵敏、内泄漏小

The rated pressure of the valve is achieved by adjusting

the spring force and allows free flow from P to T while

the pressure at P reaches the valve setting;In the opposite 

direction free flow from T to P at very low pressure. The 

valve offers quick response and low internal leakage.
