Bard 5651-223BX - Expansion Valve 3/8 x 3/8
Bard part 5651-223BX is an OEM thermal expansion valve (TXV) used in Bard wall mount air conditioning systems to meter refrigerant into the evaporator and maintain proper superheat across changing loads. With 3/8 inch by 3/8 inch connections and boxed for protection, this valve is a common replacement when a system shows symptoms like unstable suction pressure, poor cooling, or icing related to a restricted or malfunctioning metering device. Using the correct Bard OEM valve helps keep refrigerant flow matched to the coil design so the unit can return to normal capacity and efficiency after service.

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.
