- Working principle of imported liquid nitrogen cryogenic solenoid valve: <
- Normally closed type: when the coil is energized, the pilot valve core attracts and closes the pilot hole to open the upper chamber of the valve and the pressure relief piston moves downward. The pressure of the cavity medium pushes the solenoid valve to open; when the coil is powered off, the pilot spool is reset by the spring, and the pilot hole is closed. The upper chamber of the valve is closed by the pressure of the piston orifice and the thrust of the return spring.
- Normally open type: When the coil is energized, the pilot hole is closed and the upper chamber of the valve is closed by the piston orifice booster and the thrust solenoid valve of the return spring. When the coil is powered off, the pilot spool is reset by the spring. The pilot hole opens the upper chamber of the valve and the pressure relief piston pushes the solenoid valve open by the medium pressure in the lower chamber.
