(高溫)進口導熱油，蒸汽電磁閥 主要性能 Main performance

常閉 Normally closed:

當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開 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

當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉  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

常開 Normally open:

當線圈通電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉 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

當線圈斷電時，先導閥芯靠彈簧復位，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開 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：當電磁閥2號線圈瞬間通電后斷電，電磁閥打開 When the No. 2 coil of the solenoid valve is momentarily energized, the power is cut off and the solenoid valve opens

B：當電磁閥1號線圈瞬間通電后斷電，電磁閥關閉 When the No. 1 coil of the solenoid valve is momentarily energized, the power is cut off and the solenoid valve is closed

信號反饋 Signal feedback：

當電磁閥打開時，信號公共線和開信號線接通  When the solenoid valve is opened, the signal common line and the on signal line are connected

當電磁閥關閉時，信號公共線和關信號線接通  When the solenoid valve is closed, the signal common line and the off signal line are connected

注：出口端壓力大于進口端壓力，介質會反向導通?？砂惭b止回閥

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
