Bard 5651-229BX - Thermal expansion valve
Bard 5651-229BX is an OEM thermal expansion valve used in Bard wall mount and package air conditioning equipment to meter refrigerant into the evaporator and maintain stable superheat under changing load conditions. With 3/8 in by 3/8 in line connections, this valve helps restore proper cooling performance when a system is starving or flooding the coil due to a sticking or restricted metering device. Because refrigerant type, tonnage, and valve charge must match the specific unit, confirm fitment by model and serial number before ordering, and have installation performed by a licensed HVAC technician following proper evacuation and charging procedures.

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.
