Working principle of cryogenic solenoid valve
Normally open type When the coil is energized, the pilot hole is closed, and the upper chamber of the valve is throttled by the piston The hole is pressurized and the thrust of the return spring causes the solenoid valve to close. When the coil is powered off, the pilot valve core returns by the spring, the pilot hole opens, the upper chamber of the valve relieves pressure, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens.
Normally closed type: When the coil is energized, the pilot spool is closed, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened. When the coil is deenergized, the pilot spool is pressed against the spring. When reset, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed.
Installation matters for imported cryogenic solenoid valves

Before installing the solenoid valve, read the instruction manual of the product in detail and check whether the parameters meet your industrial and mining requirements.
Before installing the solenoid valve, flush the pipeline with high-pressure water. If the medium is unclean or contains impurities, a filter should be installed to prevent impurities from affecting the normal opening of the solenoid valve.
After the solenoid valve has been out of use for a long time, the condensation should be removed, and then the solenoid valve should be opened for cleaning. During cleaning, the parts should be placed in order so that they can be quickly reinstalled and put into use.
