This series valve is available as a pressure differential pilot actuated valve as
well as an Actuator driven valve
In the NORMAL POSITION, the discharge gas goes straight through the valve causing almost no pressure drop. The Reheat/Defrost coil is closed off inside the valve. In the ENERGIZED POSITION the discharge gas turns 90 degrees through the valve going out to the Reheat/Defrost coil. The out port is closed off inside the valve. Discharge pressure is piped to the small port opposite the Reheat/Defrost port so this valve can be used to shift suction pressure. This diagram is a typical compressor unloading configuration.
