Bard part 5651-188 is an OEM thermal expansion valve used in Bard wall-mounted air conditioners and similar packaged equipment to meter refrigerant into the evaporator coil based on load. When a TXV is sticking, restricted, or misfeeding, you can see symptoms like poor cooling, coil freeze-up, high superheat, or unstable suction pressure, and replacing the valve can help restore proper refrigerant control and system performance. Because TXVs are application-specific for refrigerant, tonnage, and connection style, confirm 5651-188 against your unit model and serial number in the Bard parts list or service manual before ordering, and have a qualified technician handle refrigerant recovery and brazing during installation.
