Alco Controls XB1019FW Thermal Expansion Valve Power Assembly

Alco Controls XB1019FW Thermal Expansion Valve Power Assembly is a replaceable power element for Alco’s Thermo Expansion Valve family, designed to drive the XB1019 valve body in refrigeration equipment. The FW variant, specified for evaporating temperatures from -40°F to 50°F, fits low-to-moderate evaporator conditions and pairs with take-apart Thermo Expansion Valves to provide electrical actuation that positions the valve in response to control signals. As part of the XB-series power elements, XB1019FW configurations appear in distributor literature (for example XB1019FW1B), confirming compatibility with multiple XB-series valve bodies. When servicing or upgrading an XB1019-based system, selecting the matching XB1019FW power assembly ensures the correct opening range and responsive control without replacing the entire valve assembly.
