5651-219 OBSOLETE
- Check Valve 1/2 X 1/2
Bard part number 5651-219 is an OEM 1/2 in x 1/2 in check valve used in the refrigerant circuit on select Bard wall-mounted packaged heat pump units, including dehumidification configurations where one-way flow control is critical to proper operation. This valve helps maintain correct refrigerant direction through the system during specific operating modes, which supports stable capacity and protects other components from reverse-flow conditions. For a trouble-free replacement, confirm the exact model and revision of your Bard unit and match the connection size before ordering, since check valve placement and quantity can vary by unit configuration.
