These valves are servo operated main valves with screwed-on pilot solenoid valves.
These valves use an external pressure source for opening (which means that no differential pressure across the valve is required in order to maintain open state)
This makes the valve especially suitable for low-pressure suction lines.
This valve can be used in all types of refrigeration systems.
Within their specified pressure and temperature range These valves can be used for fluorinated refrigerants (R22,R134A,R404A,R12,R502 and Ammonia (R717)
These pilot operated solenoid valves can be installed in.
