Bard 5651-139 - Expansion Valve 3/8 x 3/8

The Bard 5651-139 expansion valve is an OEM refrigerant metering component used in Bard wall-mounted air conditioners to regulate refrigerant flow into the evaporator coil for stable superheat and reliable cooling performance. With 3/8 inch by 3/8 inch connections, this valve helps correct symptoms tied to improper refrigerant feeding such as coil icing, poor capacity, and erratic suction pressure when the rest of the sealed system is in good condition. Because application can vary by model and refrigerant type, match Bard 5651-139 to your unit model and serial number parts list before ordering, and install using proper refrigeration practices including evacuation and weigh-in charging per the unit specifications.
