How much ZCH corrosion corrosion solenoid valve solenoid valve Shanghai?

The main technical parameters: Specifications: DN1 ~ DN500 Body material: stainless steel, PTFE, PVC Medium: corrosive fluid gas medium temperature: 0 ℃ ~ + 250 ℃ Medium viscosity: to be customized less than 50CSt (greater than 50 ) Applicable pressure: 0.01MPa ~ 0.6MPa 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 works: NC: When the coil is energized , the pilot spool pull open the pilot hole, the pressure relief valve chamber, the piston on the lower chamber medium pressure to promote 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.
