ZCW2 cryogenic solenoid valve solenoid valve Shanghai brand suppliers

The main technical parameters: Specifications: DN1 ~ DN200 Body material: stainless steel Medium: nitrogen, carbon dioxide, Freon medium temperature: -200 ℃ Medium viscosity: less than 50CSt (greater than 50 to be customized) protection performance: waterproof, explosion-proof (Exd IICT5 ), corrosion Spool Material: Stainless steel were Wiring: Terminal Block type, lead type, male Control: Normally open, normally closed Supply voltage: DC24 ~ 127V; AC36 ~ 380V Connection: thread, flange, ( male and special interfaces or add custom adapter) Leakage: Zero Note: Special type can be customized cryogenic solenoid valve works: NC: When the coil is energized, the pilot spool pull open the pilot hole, the valve chamber and unloading pressure piston driven by medium pressure chamber, the solenoid valve is opened. When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed. Normally open: When the coil is energized, the pilot valve by the spring return, pilot hole closed, valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote the solenoid valve is opened. Note: The outlet pressure is greater than the inlet end of the pressure, the media will reverse pass. Check valve can be installed.
