Bard 5651-231BX - Expansion Valve
Bard part number 5651-231BX is an OEM expansion valve supplied boxed, used as the refrigerant metering device that regulates liquid refrigerant flow into the evaporator to maintain proper system operation and help protect the compressor from floodback. When an expansion valve sticks, hunts, or loses control, you can see symptoms like poor cooling, unstable suction pressure, coil icing, or reduced capacity, and replacing it with the correct Bard valve is the best way to restore the designed refrigerant feed and overall performance. As with any refrigerant circuit repair, confirm the exact unit model and refrigerant type match, replace the filter drier if required by your service procedure, and follow proper evacuation and charging practices to ensure a clean, reliable repair.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
