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) 直 动 式 带 逆流单向 阀 的顺序 阀 将在 进 口 （口1）压力超 过 阀的设定 之 后向次 级 油 路 供 油。此外 ， 此类阀 内 部集 成 单 向阀， 可 以提供 从 口2（顺序 口 ）到 口1（进口 ） 逆向液 流 。顺序 阀 的设定 将 控制与 外 泄口（ 口3） 压 力相 关 的 口1压 力。 Direct-acting sequence Valve with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these Valve incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequenc
