Bard part 5651-175 is an OEM thermostatic expansion valve (TXV) used in Bard wall-mounted air conditioners and heat pumps to meter refrigerant into the evaporator coil and maintain proper superheat for stable, efficient cooling. A correctly matched TXV helps prevent coil flooding or starved operation that can lead to poor capacity, nuisance trips, or compressor stress. Because TXVs can vary by refrigerant type, tonnage, and connection details, confirm 5651-175 is the exact part number listed for your specific Bard model and serial before ordering, then install using standard refrigeration best practices including system evacuation, proper charging, and leak checks.
