Butterfly Valve

  • Flanged / Wafer Type Triple Eccentric Butterfly Valve for sour and alkaline medium

    Flanged / Wafer Type Triple Eccentric Butterfly Valve for sour and alkaline medium

    Triple eccentric butterfly valve, the valve stem shaft center deviates from the center of the plate and the body center, and the seat rotation axis has an angle from the axis of the body channel. When the valve is fully open, the plate sealing surface will completely deviate from the seat sealing surface. When the plate opens from 0 to 90 degrees, the plate sealing surface gradually leaves the seat sealing surface, and the valve opens. When the plate opens from 90 to 0 degrees, the plate sealing surface gradually approaches the seat sealing surface, and then press and the valve closes.

  • Soft Seal Bi-direction Butterfly Valve

    Soft Seal Bi-direction Butterfly Valve

    Butterfly valve is one of obstructing valves to connect or block the medium in the pipeline, it can also adjust the flow of medium in the pipeline. Its closing element (disc) is in the shape of disc that can revolve the axis itself to block the medium in the pipeline or adjust the flow.

  • Metal Seated Bi-directional Butterfly Valve

    Metal Seated Bi-directional Butterfly Valve

    Metal seated bi-direction butterfly valve adopts double eccentric structure, the structure of double eccentricity greatly eliminates the unnecessary excessive extrusion and scraping phenomenon of the plate and the valve seat. The large reduction of scraping makes the butterfly valve with the metal valve seat improve the performance.

  • Central Line Wafer Butterfly Valve

    Central Line Wafer Butterfly Valve

    Central line wafer butterfly valves are used cut-off or connect the medium in the line. The steering center of the butterfly plate is on the center line of the valve body and the butterfly plate seal area. When the valve is closed, the circumscribed sealing surface of the butterfly plate will squeeze out the synthetic rubber valve seat and produce elastic deformation on the valve to ensure the sealing of the butterfly valve.
