Description
The Copeland 054778 is a medium temperature, externally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in commercial and residential HVAC/R systems. Designed for use with R-22 and R-407C refrigerants, this valve delivers precise superheat control across a wide range of operating conditions, making it an ideal drop-in solution for both new installations and retrofit applications.
With a 5-1/2 ton capacity rating and a 5-foot capillary tube, the 054778 provides the flexibility needed to position the sensing bulb accurately on the suction line. The 1/2″ x 5/8″ ODF sweat connections ensure compatibility with standard copper line sets and simplify field installation.
