Bard part number 5651-094BX is an OEM thermal expansion valve with 3/8 inch by 3/8 inch connections, used to meter refrigerant flow into the evaporator so the system can maintain proper superheat and stable cooling performance. A failing or restricted TXV can lead to poor capacity, coil icing, or erratic suction pressure, so replacing it with the correct Bard-specified valve helps restore the intended refrigerant control and protects the compressor. This 5651-094BX valve is commonly referenced as an R-22, 1 ton TXV, so confirm refrigerant type and tonnage match your specific Bard unit before ordering to ensure proper fit and operation.
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.
