Water solenoid valve normally closed Working principle:
Normally closed type: when the coil is energized, the pilot spool pulls, the pilot hole opens, the valve chamber pressure relief, the piston on the lower chamber medium pressure to promote, the solenoid valve open; When the coil power, the pilot spool by the spring return, pilot hole closed, the valve chamber by the piston throttle hole pressurized and reset the thrust of the spring, the solenoid valve is closed.
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
