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口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 toT while the pressure at P reaches thevalve setting;In the opposite direction free flowfrom T to P at very low pressure. The valveoffers quick response and low internal leakage.
