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，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

阀体材质	不绣钢								铸铁
适用压力	0.01～6.4MPa								0.01～1.6MPa

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀或订制自带止回功能的阀。Applications: 
It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, industrial furnaces, boilers, plumbing, heating and air conditioning, fire fighting equipment, drying equipment, food and medical equipment, cleaning equipment, landscape irrigation, water and other piping systems. p> p>Features:
Pilot structure, the spool is stainless steel piston, piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve mounting direction unlimited; authoritarian coil and difficult to burn; long restart action to stop the action as sensitive; leakage is zero; life of up to 100 million times.Main technical parameters:

Specifications:	DN6 ~ DN1000
Body material:	Steel body, stainless steel (steel body can not be used in corrosive fluid on)
Pressure range	0.01 ~ 6.4MPa; 0.01 ~ 1.6MPa
Medium:	Water, gas, oil, steam, gas, corrosive fluids
Temperature range:	-200 ~ +300 ℃
Media Viscosity:	Less than 50C St (greater than the time to be customized)
Protection performance:	Waterproof, explosion-proof (Exd IICT5), anti-corrosion
Wiring:	Terminal Block Type; lead type, male
Control:	Normally open, normally closed
Power supply voltage:	DC12 ~ 127V; AC36 ~ 380V
Connection:	Thread, flange (male and special interfaces or add custom adapter)

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