Emerson Flow Control (Alco) 063644 Power Head 5FT Capillary SAE XB1019RW35

Emerson Flow Control (Alco) 063644 Power Head is an internal part of some models of Alco Thermal Expansion Valves (TXVs). This power head with a 5-foot capillary tube is identified as XB1019RW35 and serves as the driving force for the internal components of the TXV. This efficiently transcribes electrical or other forms of energy into mechanical energy to allow the TXV to regulate the flow of refrigerant into the evaporator. The power head plays an essential role in the right circulation of refrigerant which leads to an increase in efficiency, decreased energy consumption, and therefore increased HVAC systems performance.
