5651-189 OBSOLETE
- Expansion Valve
Bard 5651-189 is an OEM thermostatic expansion valve (TXV) used in Bard wall mounted air conditioning equipment to meter refrigerant into the evaporator coil and maintain proper superheat for stable cooling and compressor protection. When a TXV sticks, hunts, or loses charge, you can see poor capacity, icing, or erratic suction pressure, so replacing it with the correct Bard part is important for fit and system performance. Bard lists 5651-242 as the factory replacement for 5651-189, and some applications may require minor piping alignment changes during installation, so confirm your unit model and the connection details before ordering.
