< German Lake brand - imported nitrogen low-temperature solenoid valve is suitable for various ultra-low temperature fluids such as: Freon, liquid carbon dioxide, refrigerant, liquid nitrogen, liquid oxygen, liquid ammonia. The ultra-low temperature liquid nitrogen solenoid valve is designed with special low-temperature resistant materials. It is compact in appearance and exquisite in appearance. The special coil is not easy to The burnt piston structure is durable and wear-resistant, with reliable quality.

-Working principle of liquid nitrogen solenoid valve:
-Normally open type: When the solenoid valve coil is energized, the pilot hole is closed and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring. The solenoid valve is closed; when the solenoid valve coil is powered off, the pilot valve core is reset by the spring, and 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.
-Normally closed type: When the solenoid valve coil is energized, the pilot valve core attracts the pilot hole to open the upper chamber of the valve, and the pressure relief piston pushes the solenoid valve open by the medium pressure in the lower chamber; when the solenoid valve coil is deenergized, the pilot valve core The upper chamber of the spring return pilot hole closing valve is closed by the piston orifice booster and the thrust solenoid valve of the return spring.
