(高温)进口导热油，蒸汽电磁阀 主要性能 Main performance

常闭 Normally closed:

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 RETZ When the coil is energized, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened

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  RETZ When the coil is powered off, the pilot valve element is returned by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed

常开 Normally open:

当线圈通电时，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 When the coil is energized, the pilot valve element is returned by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed

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 When the coil is powered off, the pilot valve element is reset by the spring, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened

自保持式 Self holding

A：当电磁阀2号线圈瞬间通电后断电，电磁阀打开 When the No. 2 coil of the solenoid valve is momentarily energized, the power is cut off and the solenoid valve opens

B：当电磁阀1号线圈瞬间通电后断电，电磁阀关闭 When the No. 1 coil of the solenoid valve is momentarily energized, the power is cut off and the solenoid valve is closed

信号反馈 Signal feedback：

当电磁阀打开时，信号公共线和开信号线接通  When the solenoid valve is opened, the signal common line and the on signal line are connected

当电磁阀关闭时，信号公共线和关信号线接通  When the solenoid valve is closed, the signal common line and the off signal line are connected

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀

Note: if the pressure at the outlet end is greater than that at the inlet end, the medium will conduct reversely. Check valve can be installed
