当P口压力上升到一定水平，由于阀芯内外的面积差使得该阀芯相当于阀座被打开，P到T开始溢流。该类型的阀反应灵敏，内泄漏小，相对于标准直动式溢流阀压降比较小，适用于较大流量场合

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.
