Normally open stainless steel solenoid valve application:
Normally open stainless steel solenoid valve is suitable for neutral pure gas or liquid, especially air, water, hot water, gas, natural gas, diesel and other pipeline control system; Military, aerospace, shipbuilding heavy industry, nuclear industry, petrochemical, electric power, chemical, light industry, machinery, scientific research, industrial kiln, drying equipment, boiler, water supply and drainage, air conditioning, fire, food medical, cleaning equipment, pipeline medium automation control and other fields.
Normally open stainless steel solenoid valve Product features:
Precision casting, exquisite appearance; 
Pilot piston structure, stable performance; 
Good sealing, quick switching; 
Autocratic coil, not easy to burn; 
Service life as long as five million times.

Normally open stainless steel solenoid valve Working principle:
Normally open type: when the coil is energized, the pilot hole is closed, the valve chamber is pressurized by the piston throttle hole and the thrust of the reset spring, the solenoid valve is closed. When the coil power, the pilot spool 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.

Check function: the outlet end is greater than the inlet end pressure, the medium will be anti - guide through. Check valves can be installed or customized with check function.

Manual control:
Normally closed - when the solenoid coil is not energized or burned out, the valve can be opened manually. However, the valve cannot be controlled automatically when it is manually opened.
Normally open - when the solenoid coil is not energized or burned out, the valve can be closed manually. But manual in the off state can not automatically control and coil power and power, the valve can not play
