Bard 5651-137BX - Expansion Valve 3/8 x 3/8
The Bard 5651-137BX is an OEM thermal expansion valve used in Bard wall-mount air conditioners to meter refrigerant into the evaporator coil and maintain proper system superheat under changing load conditions. With 3/8 inch x 3/8 inch connections, this valve is a direct-fit replacement intended to restore stable cooling performance and help prevent common issues tied to incorrect refrigerant feeding, such as poor capacity, coil icing, or compressor stress. Because expansion valves can vary by unit model, refrigerant type, and application, confirm the exact Bard model and serial details before ordering to ensure the correct match.

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.
