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 Preaches 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.
