Bard 5651-197 - Expansion Valve

The Bard 5651-197 expansion valve is an OEM refrigerant metering component used in Bard wall mounted HVAC equipment to regulate refrigerant flow into the evaporator coil based on system load, helping maintain proper superheat and stable cooling performance. A properly matched Bard valve is critical for correct coil feed and compressor protection, so this part is a good fit when you are correcting symptoms like erratic suction pressure, poor capacity, or a valve that will not respond to load changes. Because application details like refrigerant type, tonnage, and connection style can vary by model and revision, confirm compatibility using your unit data plate and the Bard parts list before ordering and follow standard refrigerant handling and evacuation practices during installation.
