5651-151 OBSOLETE
- Expansion Valve 3/8" X 3/8"
Bard part number 5651-151 is an OEM thermal expansion valve with 3/8 inch by 3/8 inch connections that meters refrigerant into the evaporator to maintain proper superheat and stable cooling performance. When an expansion valve sticks, hunts, or becomes restricted, you can see symptoms like poor capacity, coil icing, or erratic suction pressure, and replacing it with the correct Bard valve helps restore the unit’s designed refrigerant control and reliability. Because this is a refrigerant circuit component, confirm the exact model and serial range compatibility before ordering, and have installation handled by a qualified HVAC technician following proper recovery and brazing practices.
