Working Principle:
Normally Closed: when the coil is energized, the pilot valve plug, the pilot hole open, the valve chamber pressure relief, the piston by the lower chamber pressure to promote the solenoid valve open; when the coil powered off, the pilot valve spring reset, The pilot hole is closed, the valve chamber is pressurized by the piston orifice and the thrust of the return spring, the solenoid valve is closed. | |
