This series valve is available as a pressure differential pilot actuated valve as
well as an Actuator driven valve
In the NORMAL POSITION the C and NC ports are open through the valve and the NC port is closed off inside the valve. Discharge pressure must be supplied to the 1/4″ flare on the side of the valve. The 1/4″ flare fitting at the pilot (below the coil) must be piped to the suction side of the compressor. In the ENERGIZED POSITION the C and NC ports are open through the valve and the NO port is closed off inside the valve. This diagram is a typical hot gas defrost configuration.
