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 byadjusting the spring force and allows free flowfrom P to T while the pressure at P reaches thevalve setting; In the opposite direction free flowfrom T to P at verylow pressure. The valveoffers quick response and low internal leakage.
