How it works:

NC: When the coil is energized, the pilot spool pull, pilot hole open cavity pressure relief valve, the piston on the lower chamber medium pressure to promote, solenoid valve opens; When the coil is de-energized, the pilot valve by spring return, the pilot hole is closed, the valve chamber and the piston orifice and the return spring force booster, the electromagnetic valve is closed.

Normally open: when the coil is energized, the pilot hole is closed, the valve chamber and the piston orifice, and the return spring force booster, the solenoid valve is closed. When the coil is de-energized, the pilot valve by spring return, pilot hole opened, pressure relief valve chamber, the piston on the lower chamber medium pressure to promote, the solenoid valve opens.

Return function: inlet pressure is greater than the outlet end, the media will reverse conduction. Check valve can be installed or custom built-return valve function.
