當(dāng)P口壓力上升到一定水平，由于閥芯內(nèi)外的面積差使得該閥芯相當(dāng)于閥座被打開，P到T開始溢流。該類型的閥反應(yīng)靈敏，內(nèi)泄漏小，相對(duì)于標(biāo)準(zhǔn)直動(dòng)式溢流閥壓降比較小，適用于較大流量場(chǎng)合

When the pressure at”p”rises a certain level.Due to the area difference between the inside and outside of the spool.It is opened relative to the valve seat, Starting to overflow from p to T.This type of valve have fast response and low internal leakage,Have a lower pressure drop than the standard directing acting relief valves, Suitable for the larger flow situations.
