• Expansion Valve 3/8" X 3/8"

Bard part 5651-234 is an OEM expansion valve with 3/8 in x 3/8 in connections used to meter refrigerant into the evaporator coil on Bard wall-mounted air conditioners. When the correct valve is installed and properly sealed, it helps maintain stable superheat and keeps the system operating efficiently by delivering the right refrigerant feed under changing load conditions. This component is a fit-critical refrigeration part, so confirm the exact Bard model and serial number application before ordering and plan on having a licensed HVAC technician handle refrigerant recovery, brazing, evacuation, and final charging to Bard specifications.
