Principle of Operation - SR
Open stroke/打开动作: 1) Pump starts. Bypass valve opens to allow oil to tank while motor starts. 液压泵启动时，旁通电磁阀打开， 油直接进入油箱。 2) Bypass and Close solenoid valves close forcing oil into cylinder.旁通和关电磁 阀关闭时，油进入液压缸。 3) Bypass valve opens to stop actuator, then pump stops after run-on time. 旁通电磁阀打开，执行机构停止， 泵在运行时间以后停止动作。 Close stroke/关闭动作: 1) Close solenoid de-energized, allows oil to flow to tank.关电磁阀失电，油直 接泄放到油箱。
