5651-101 OBSOLETE
- Expansion Valve 7/8X1/2X1/4ODF
Bard part number 5651-101 is an OEM refrigerant metering expansion valve used in Bard wall mounted air conditioners and packaged HVAC equipment to regulate refrigerant flow into the evaporator, helping maintain correct superheat and stable cooling performance. This valve is commonly referenced as an ODF connection style expansion valve with 7/8 x 1/2 x 1/4 ODF (also listed by some sources as 3/8 x 1/2 x 1/4 ODF), so confirming the connection sizes against your unit model and service literature before ordering is important. When an expansion valve sticks, plugs, or loses control, symptoms can include poor cooling, coil icing, or unstable suction pressure, and replacing with the correct Bard OEM valve helps restore proper system operation and fit.
