Emerson Flow Control (Alco) 046474 Power Assembly R502 5'Capillary SAE EE

The Emerson Flow Control (Alco) 046474 Power Assembly is an internal part of some models of Alco Thermal Expansion Valves (TXVs) for R-502 refrigerant. This power assembly which consists of a 5-foot capillary tube is used to drive the internal mechanism of the TXV. It efficiently transcribe electrical or other types of energy into mechanical movement so that the TXV can accurately regulate the flow of the refrigerant into the evaporator. Through proper flow of refrigerant, the power assembly plays a crucial role in increasing the efficiency of the HVAC systems, minimizing energy utilization, and increasing the efficiency of the systems.
