Zusammenfassung:	A suction valve of a multiple-compressor heating ventilation and air conditioning (HVAC) system includes a valve housing including a valve inlet conduit to direct a flow of refrigerant from a heat absorption heat exchanger of the HVAC system into the suction valve, and a plurality of valve outlet conduits. Each valve outlet conduit of the plurality of valve outlet conduits is configured to direct the flow of refrigerant from the suction valve to a different compressor of the HVAC system. A valve seat is located in the valve housing. The valve seat has a plurality of valve passages extending therethrough. The valve seat is one or more of movable along a valve axis and rotatable about the valve axis to selectably direct the flow of refrigerant to one or more compressors of the HVAC system depending on a position of the valve seat in the valve housing.
