Bard 5651-082BX - R22 TXV expansion valve

The Bard 5651-082BX is an OEM thermostatic expansion valve (TXV) used in Bard wall-mount and other compatible Bard air conditioning equipment to meter refrigerant flow into the evaporator and maintain proper superheat for stable cooling performance. This boxed valve is specified for R22 systems and is commonly identified as an SVE-4-N style expansion valve with 1/2 inch by 7/8 inch ODF connections, making correct matching critical for both fit and refrigerant control. Use Bard part number 5651-082BX when replacing a restricted, leaking, or improperly feeding metering device, and confirm compatibility by model and serial number before ordering since TXV selection can vary by unit and refrigerant circuit.

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.
