5651-163 OBSOLETE
- Expansion Valve 3/8 X 3/8
Bard part 5651-163 is an OEM thermostatic expansion valve with 3/8 in x 3/8 in connections that meters refrigerant into the evaporator coil on compatible Bard wall-mount and packaged HVAC units. A properly operating TXV helps maintain stable superheat and protects system efficiency by feeding the coil correctly across changing loads. This is the right choice when troubleshooting issues like improper refrigerant feeding, icing, or poor cooling tied to a restricted or malfunctioning metering device. Confirm fit by matching the part number to your Bard unit model and serial, since valve selection can vary by system configuration and refrigerant application.
