Bard 5651-239BX - Thermal expansion valve
Bard part number 5651-239BX is an OEM thermal expansion valve (TXV) supplied boxed with 3/8 inch by 3/8 inch connections, used as the refrigerant metering device that feeds the evaporator coil in many Bard wall mount and packaged HVAC units. A properly matched TXV helps maintain correct superheat and stable suction pressure, which supports consistent cooling performance and helps protect the compressor from liquid floodback. This is a fit-critical refrigerant component, so confirm the exact Bard model and serial compatibility before ordering, and follow standard refrigerant handling practices during replacement including evacuation and leak checking.

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.
