5651-181 OBSOLETE
- Expansion Valve
Bard part number 5651-181 is an OEM expansion valve used to meter refrigerant into the evaporator coil at the correct rate so your Bard wall-mount air conditioner or heat pump can maintain stable superheat, protect the compressor, and deliver consistent cooling. When a system shows symptoms like poor cooling, frosting at the coil, or erratic suction pressure, a worn or restricted valve can be a common root cause, and replacing it with the correct Bard OEM valve helps restore factory performance and fit. Because expansion valves are application-specific by refrigerant and capacity, confirm compatibility by matching the unit model and serial number to the Bard parts list before ordering, and follow proper brazing and evacuation practices during installation.
