Pilot Operated Solenoid Valve

Pilot Operated Solenoid Valve is suitable for all refrigerants except ammonia. This valve is applicable for CFC & HCFC as a supplementary device to thermostatic expansion valves. It is used in place of capacity solenoid valves for positive shut-off of liquid lines. The Solenoid Pilot Control does not directly close the liquid line, but acts on the thermostatic expansion valve causing the expansion valve to close. This is installed in the external equalizer line of the thermostatic expansion valve, and has a third 1/4 "connection from the liquid line.
