Description
The Copeland XC-726SW402B (SKU 063127) is a thermostatic expansion valve (TXV) power assembly engineered for reliable refrigerant metering in low-temperature R404A refrigeration systems. Supplied complete with capscrews for straightforward field installation, this power assembly is a direct-replacement solution for commercial refrigeration applications requiring precise superheat control.
Key Features
- Designed for use with R404A refrigerant
- 1/4″ SAE flare connection with equalizer-type fitting for accurate pressure sensing
- 10-foot capillary tube length for flexible bulb placement and routing
- Application temperature range: -50°F to +10°F — ideal for low-temperature and frozen food cases
- Maximum Operating Pressure (MOP): 40 PSI — protects the compressor from high suction pressure during pull-down
- Capscrews included for complete, ready-to-install assembly

Application
This power assembly is suited for low-temperature commercial refrigeration systems such as reach-in freezers, walk-in coolers, and display cases operating in the -50°F to +10°F range. The 40 PSI MOP rating limits suction pressure during warm pull-down conditions, safeguarding the compressor from overload. The equalizer-type flare connection ensures accurate pressure equalization across the valve for consistent superheat control throughout varying load conditions.
