【工作原理 Working principle】

常闭式：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开；当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

Normally closed:when the coil is energized,the pilot spool pull,open the pilot hole,cavity pressure relief valve,the piston on the lower chamber medium pressure to promote,the electromagnetic valve is opened;when the coil power, the pilot valve by the reset spring,the pilot hole is closed,valve chamber by the piston orifice booster and a reset spring thrust,the electromagnetic valve closed.

常开式：当线圈通电时，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

Normally open: when the coil is energized,the pilot hole is closed,the valve is closed by the piston throttle orifice and the thrust of the spring. When the coil power,the pilot valve by the spring reset,the pilot hole to open,the valve on the chamber pressure,the piston is driven by the pressure of the cavity media,solenoid valve open.

【应用范围 Scope of application】

军工、航天、船舶重工、核工业、石化、电力、化学、轻工、机械、科研、给排水等领域，最适用于阀出口会产生比进口压力大、不需反向流通的管道系统。

the mi,itary,aerospace,shipbuilding,nuclear industry,petrochemical,power,chemical,lighlindustry,machinery,scientific research,such as water supply and drainage areas,the most applicable to the valve outlet will produce than the inlet pressure,without reverse circulation pipeline system.

【注解 Note】

流体中若含有杂质，电磁阀进端必须安装过滤器。

If the fluid contains impurities, the solenoid valve into the end must be installed in the filter.
