Bard 5651-131BX - 3/8 x 3/8 ODF Expansion Valve
The Bard 5651-131BX is an OEM thermostatic expansion valve with 3/8 x 3/8 ODF connections, designed to meter refrigerant into the evaporator coil so your Bard wall-mounted air conditioner can maintain stable superheat and consistent cooling. When a TXV sticks, hunts, or restricts flow, it can lead to poor capacity, coil icing, or erratic pressures, so replacing it with the correct Bard factory part helps restore proper refrigerant control and protects compressor reliability. Verify the valve size and match it to your unit and service literature before installation, since refrigerant circuit components must be selected for the specific model and application.

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.
