The Bard 905-0632BX TXV Assembly (boxed) is an OEM thermostatic expansion valve assembly used in Bard wall-mounted air conditioners and heat pumps to meter refrigerant into the evaporator coil and maintain proper superheat under changing load conditions. Replacing a restricted, sticking, or leaking TXV can help correct symptoms like poor cooling capacity, evaporator icing, or unstable suction pressure by restoring accurate refrigerant control the way Bard engineered the system. Because TXV selection depends on the exact model, refrigerant type, and system configuration, confirm the unit model and match the full Bard part number 905-0632BX before ordering to ensure proper fit and performance.
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.
