Zbf Proof and Corrosion Solenoid Valves

ZBF Proof and corrosion solenoid valves

Parameters:
Specifications: DN0.5 ~ DN1000
Body material: Stainless steel 304, stainless steel 316, stainless steel 316L, PTFE
Temperature range: -200 ~ +350 ° C
Medium: Flammable liquid or gas protection performance: Waterproof, explosion-proof, corrosion
Control: Normally open, normally closed
Power supply voltage: DC12 ~ DC127V; AC36 ~ 380V
Connection: Thread, flange (other special interfaces or add custom adapter)
Leakage: Zero
Note: Special large diameter valves can be customized, the largest diameter can be achieved DN500 (mm)

How it works:
NC(normally close): When the coil is energized, the pilot spool pull, open the pilot hole, the pressure relief valve chamber, medium pressure piston driven by the lower chamber, the solenoid valve is opened.
When the coil power, the pilot valve by spring return, pilot hole is closed, valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve is closed.
