Bard 5651-184 - Thermal Expansion Valve (TXV)

Bard part number 5651-184 is an OEM thermal expansion valve (TXV) used in Bard wall-mounted air conditioners and heat pump systems to meter refrigerant into the evaporator based on load, helping maintain proper superheat and stable capacity. This valve is specified as a 3/8 inch by 3/8 inch connection and is commonly listed for R-410A applications, making it a critical refrigerant circuit component when correcting symptoms like poor cooling, coil icing, or erratic suction pressure that can be traced to a restricted or failing TXV. For best results, confirm the exact Bard model and serial number match and follow proper refrigeration service practices for evacuation, dehydration, and leak checking after installation.
