  • 5651-225 OBSOLETE

  • Expansion Valve 3/8" X 3/8"

The Bard 5651-225 expansion valve is an OEM thermal expansion valve used in Bard wall-mounted air conditioners and heat pump systems to meter refrigerant into the evaporator at the correct rate as load conditions change. A properly functioning TXV helps maintain stable suction superheat, prevents evaporator flooding or starving, and supports efficient cooling performance, especially during varying outdoor temperatures and indoor humidity levels. This 5651-225 valve is specified with 3/8 in x 3/8 in connections, making it a direct-fit replacement when your service literature calls for this exact part number; always confirm the model and serial number match and replace the bulb and insulation exactly as originally installed for reliable operation.
