Bard 5651-199BX - Expansion valve 3/8 x 3/8
The Bard 5651-199BX expansion valve is an OEM refrigerant metering component used in Bard wall-mounted and packaged HVAC equipment to regulate refrigerant flow into the evaporator for stable coil performance and proper superheat. This boxed valve is specified with 3/8 inch by 3/8 inch connections, making it a common service replacement when a system shows symptoms like hunting, poor capacity, or inconsistent suction conditions tied to metering issues. Because TXV selection and installation details can vary by unit and refrigerant application, confirm the exact model and serial of your Bard unit and match connection style and sizing before ordering 5651-199BX to ensure correct fit and reliable operation.

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.
