Bard 5651-102BX - 3/8 x 3/8 thermostatic expansion valve
The Bard 5651-102BX is an OEM thermostatic expansion valve (TXV) with 3/8 in x 3/8 in solder connections, used to meter refrigerant flow into the evaporator coil so your Bard wall-mounted air conditioner can maintain proper superheat and stable cooling under changing loads. When a TXV sticks, hunts, or restricts flow, it can lead to poor capacity, icing, or abnormal pressures, so replacing it with the correct Bard-specified valve helps restore the system’s designed refrigerant control and overall reliability. Since this component is part of the sealed refrigerant circuit, confirm compatibility by model and serial number and have installation performed by a qualified HVAC technician using proper brazing and evacuation 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.
