Working Principle:
Normally Closed Type: When the coil is energized, the pilot valve core is attracted, the pilot hole opens, the upper chamber of the valve depressurizes, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens; when the coil is de-energized, the pilot valve core resets by the spring, the pilot hole closes, the upper chamber of the valve is pressurized by the piston throttle hole and the reset spring's thrust, and the solenoid valve closes.
Normally Open Type: When the coil is energized, the pilot hole closes, the upper chamber of the valve is pressurized by the piston throttle hole and the reset spring's thrust, and the solenoid valve closes; when the coil is de-energized, the pilot valve core resets by the spring, the pilot hole opens, the upper chamber of the valve depressurizes, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens.
Note:1. If the outlet end pressure is greater than the inlet end pressure, the medium will reverse conduct. A check valve can be installed or a valve with built-in check function can be customized.
2. External dimensions are determined based on the connection method, special requirements can be customized.
