Working Principle:
Normally Closed Type: When the coil is energized, the pilot valve core is attracted, the pilot port opens, the upper chamber of the valve depressurizes, and the piston is pushed by the medium pressure in the lower chamber, opening the solenoid valve. When the coil is de-energized, the pilot valve core resets via the spring, the pilot port closes, and the upper chamber of the valve is pressurized through the piston throttle orifice and the reset spring's force, closing the solenoid valve.
    Normally Open Type: When the coil is energized, the pilot port closes, and the upper chamber of the valve is pressurized through the piston throttle orifice and the reset spring's force, closing the solenoid valve. When the coil is de-energized, the pilot valve core resets via the spring, the pilot port opens, the upper chamber of the valve depressurizes, and the piston is pushed by the medium pressure in the lower chamber, opening the solenoid valve.
Note: If the outlet pressure exceeds the inlet pressure, the medium may flow in reverse. A check valve can be installed, or a valve with built-in check functionality can be customized.
