    Wafer Type Butterfly Valve


     Hebei Metals supplies Wafer Type Butterfly Valves.

     The wafer type butterfly valve is designed to maintain a seal against

     bi-directional pressure differential to prevent backflow in piping system 

     designed for unidirectional flow. It accomplishes this with a tightly

     fitting seal, i.e. gaket, and O-ring.
