閥的額定壓力是通過調(diào)節(jié)彈簧力實現(xiàn)，當P口壓力達到設定壓力后，閥被打開，P到T開始溢流;反方向，從T到P可以很低的壓力打開。該閥反應靈敏、內(nèi)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.
