5651-168 OBSOLETE
- Expansion Valve
The Bard 5651-168 expansion valve is an OEM refrigerant metering component used in Bard wall mounted air conditioners and heat pump style systems to regulate refrigerant flow into the evaporator based on system load, helping maintain proper superheat and stable cooling performance. When a TXV sticks, leaks, or loses charge, you can see symptoms like poor capacity, coil icing, or erratic pressures, so replacing it with the correct Bard factory part helps restore the designed refrigerant control and protects the compressor from floodback or starvation. Because expansion valves are application-specific by refrigerant and tonnage, confirm the exact unit model and serial before ordering, and plan on proper evacuation and charging procedures after installation.
