If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction ·口3处的压力直接以1:1的比例增加到阀的设定值上，口3处的压力不 能超出5000 psi(350 bar) Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar) 压力降 PRESSURE DROP psi(bar) 压力-流量性能曲 线 Performance Curve Pressure Drop vs.Flow Direct-acting sequence Valve will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exc
