Bard 5651-128 - Expansion Valve

The Bard 5651-128 expansion valve is an OEM refrigerant metering component used to regulate liquid refrigerant flow into the evaporator coil, helping your Bard wall-mounted air conditioner maintain correct superheat and stable cooling performance. A properly operating expansion valve supports efficient heat transfer and can help address symptoms like poor capacity, evaporator icing, or inconsistent suction pressure when the rest of the refrigeration circuit is in good condition. Because fit and calibration vary by model and refrigerant application, confirm 5651-128 against your unit model and serial number or the correct Bard parts manual before ordering, and plan on standard refrigeration best practices during replacement, including brazing procedures, filter drier evaluation, proper evacuation, and charge verification.
