• CHECK VALVE 3/8" BALL TYPE

Bard part number 5651-006 is an OEM 3/8 inch ball type check valve used in Bard wall mounted HVAC refrigerant piping to promote one way flow and help prevent backflow during system operation and off cycles. A properly sealing check valve supports stable pressures and reliable refrigerant management, which can reduce nuisance issues tied to reverse flow in certain circuit conditions. When replacing this component, confirm the valve size and flow direction match your unit’s refrigeration layout and install it using proper refrigeration practices to protect the sealed system and maintain Bard factory performance.
