Emerson Alco 052957 Power Assembly

The Emerson Alco 052957 Power Assembly (model XC-726FC2B) is a field-replaceable component engineered for high-performance thermal expansion valves used in R12 refrigerant systems. This XC series power assembly features a 1/4" SAE flare equalizer connection, ensuring accurate pressure sensing for precise superheat control across varying load conditions. Designed for a medium-to-low temperature range of -20°F to +40°F, it utilizes a 10ft capillary tube to provide installation flexibility in complex evaporator configurations. The assembly includes required capscrews, facilitating a secure seal and direct replacement during HVACR system maintenance. Professionals rely on the stainless steel diaphragm construction to resist corrosion and prevent fatigue failure, maintaining consistent valve modulation in commercial refrigeration applications. Integrating this Alco power element ensures the expansion valve responds correctly to evaporator outlet temperatures, maximizing system efficiency and protecting compressors from liquid slugging.
