brass miniature solenoid valve direct acting normally open NO half inch 1 / 2 " AC220V 110V 230V
working principle: NC: When the coil is energized, the pilot spool pull the pilot hole is open, the pressure relief valve chamber, the piston on the lower chamber medium pressure to promote the solenoid valve is opened; When the coil power, the pilot valve by spring return, pilot hole is closed, valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed. Normally open: When the coil is energized, the pilot hole is closed, valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed. When the coil power, the pilot valve by spring return, pilot hole is open, pressure relief valve chamber, the piston on the lower chamber medium pressure to promote the solenoid valve is opened.
