广泛应用于液压系统、矿山机械、压缩机、空分设备、
高压泵站、
清洗设备、实验装备、测试设备、CNG设备、燃气设备、机器制造等自动化控制。
工作原理：
常闭：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，阀腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
常开：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。

working principle:
NC: When the coil is energized, the pilot spool pull the pilot hole is open, the pressure relief valve chamber, the piston on the lower chamber medium pressure to promote the solenoid valve is opened; When the coil power, the pilot valve by the spring return
Bit pilot hole closed and the valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed.
Normally open: When the coil is energized, the pilot hole is closed, valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed. When the coil power, the pilot valve by the spring return, pilot hole
Open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the solenoid valve is opened.
