Bard 905-0633BX - Expansion Valve Assembly

The Bard 905-0633BX Expansion Valve Assy (boxed) is an OEM refrigerant metering component used in Bard wall-mount air conditioners and heat pumps to regulate refrigerant flow into the evaporator coil for stable superheat control and efficient capacity. If your unit is icing up, running with poor cooling, or showing symptoms consistent with a restricted or stuck valve, replacing the expansion valve assembly can restore proper refrigerant feed and help protect the compressor from floodback or starvation. Because TXV selection is system-specific, confirm this part number against your Bard unit model and serial tag or the correct Bard parts list before ordering.

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.
