• Expansion Valve

Bard part 5651-179 is an OEM expansion valve used in Bard wall-mount air conditioners and related equipment to meter refrigerant into the evaporator so the system can maintain stable cooling and proper superheat. When an expansion valve sticks, plugs, or loses charge, you can see symptoms like poor capacity, coil icing, or erratic suction pressure, and replacing it with the correct Bard OEM valve helps restore factory performance and reliability. Because expansion valves are matched to specific refrigerant circuits and capacity ranges, confirm your full model and serial number and compare the connection sizes and application in the Bard parts list or service manual before ordering 5651-179.
