Model SV solenoid valve is a once open-type or twice open-type solenoid valve to be suitable to one-way flow.
· Model SV solenoid valve is used on the liquid, air suction and hot vapor pipes of the refrigeration, cold storage and air conditioning facilities.
· Model SV solenoid valve has perfect sealing on its valve seat and sealing part.
· The coil of varies voltages is available for Model SV solenoid valve with a universal valve body.
· Model SV solenoid valve could be supplied in whole or in split, that means the valve body and coil could be supplied separately.

1) Kv value: When the pressure differential is 100 KPa, the flowrate at m³h of water in density 1 t/m³ flows the solenoid valve.
2) The MOPD of gaseous medium is about 1 bar higher than that of liquid.
