Bard 5651-221BX - Expansion Valve
Bard 5651-221BX is an OEM thermal expansion valve used in Bard wall mounted air conditioners to meter refrigerant flow into the evaporator coil and maintain stable superheat for proper cooling and compressor protection. When an expansion valve sticks, hunts, or won’t regulate correctly, the system can show symptoms like poor capacity, coil icing, or abnormal suction pressure. Replacing with the correct Bard valve helps restore designed refrigerant control and reliable performance, and this boxed OEM part is intended to match the fit and function required for Bard equipment, including models that use 3/8 inch inlet and outlet connections.

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.
