5651-170 OBSOLETE
- Expansion Valve
The Bard 5651-170 expansion valve is an OEM refrigerant metering component designed to regulate refrigerant flow into the evaporator coil so your Bard wall mounted air conditioner or heat pump can maintain proper superheat, stable suction pressure, and consistent cooling performance. A worn or sticking valve can lead to poor capacity, evaporator flooding or starving, and nuisance operating issues, so replacing it with the correct Bard factory part helps restore the unit’s intended refrigerant control and reliability. Because TXV selection depends on the specific model, refrigerant, and piping configuration, match Bard 5651-170 to your unit’s part list before ordering and have installation handled by a licensed HVAC technician to ensure correct system evacuation and charging.
