Bard 5651-224 - Expansion Valve 3/8 x 3/8

Bard part 5651-224 is an OEM thermal expansion valve with 3/8 inch by 3/8 inch connections, used in Bard wall mount and packaged HVAC systems to meter refrigerant into the evaporator coil and maintain proper superheat for stable cooling performance. Replacing a restricted or malfunctioning TXV can help correct symptoms like poor capacity, coil icing, or erratic suction pressure, and using the correct Bard valve helps ensure the unit matches factory flow characteristics and controls. Confirm the unit model and refrigerant type requirements in the Bard parts list before ordering, and plan on standard refrigeration best practices such as proper brazing procedures, evacuation, and a full system charge check after installation.
