Emerson Flow Control (Alco) 061948 Power Assembly 10' Capillary XB1019SZ-2

The Emerson Flow Control (Alco) 061948 Power Assembly is an internal assembly of certain models of Alco Thermal Expansion Valves (TXVs). This power assembly with a 10-foot capillary tube marked as XB1019SZ-2 serves as the motive force for the internal workings of the TXV. It efficiently transcribes electrical or other kinds of energy into mechanical movement to allow the TXV to regulate the flow of refrigerant into the evaporator properly. Through proper flow of refrigerant, the power assembly plays a vital role in increasing system efficiency, minimizing energy consumption, and increasing the performance of HVAC systems.
