Bard 5651-158BX - Thermostatic Expansion Valve
Bard part number 5651-158BX is an OEM thermostatic expansion valve (TXV) used in Bard wall-mounted air conditioners to meter refrigerant into the evaporator and maintain stable cooling performance under changing loads. This boxed valve is specified with 3/8 inch by 3/8 inch connections, making it a common service replacement when a system shows symptoms like improper superheat control, icing, or inconsistent suction pressure. Because TXVs are application-specific, confirm the part number and connection size against your Bard unit model and service literature before ordering to ensure proper fit and correct refrigerant control.

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.
