5651-012 OBSOLETE
- EXPANSION VALVE
Bard part number 5651-012 is an OEM expansion valve used in Bard wall-mounted air conditioners and heat pumps to meter refrigerant into the evaporator coil and maintain proper superheat under changing load conditions. Replacing a restricted or failing valve can help correct symptoms like coil frosting, poor cooling, erratic suction pressure, and unstable capacity. Because expansion valves are system-specific by tonnage, refrigerant, and connection style, match 5651-012 to your exact Bard model and serial number before ordering, and have installation performed by a qualified technician due to refrigerant handling and brazing requirements.
