Bard 5651-151BX - Thermal Expansion Valve

Bard part 5651-151BX is an OEM thermal expansion valve supplied boxed with 3/8 in x 3/8 in connections, designed to meter refrigerant into the evaporator so your Bard wall mount air conditioner can maintain proper superheat and stable cooling performance. A properly matched TXV is critical for preventing coil floodback or starvation that can show up as poor capacity, icing, or erratic suction pressure, so this factory Bard valve is the right choice when you are restoring the refrigerant metering device during a sealed system repair. Confirm the exact model and serial number application before ordering, and replace the filter drier and evacuate and weigh in the charge per Bard procedures whenever the system is opened.

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.
