    D671X Pneumatic Wafer Type Soft Seal Butterfly Valve
    D671X Pneumatic Wafer Type Soft Seal Butterfly Valve

    Product Overview of D671X Pneumatic Wafer Type Soft Seal Butterfly Valve
    Wafer soft-sealed butterfly valve developed by our company has compact structure, easy 90 ° rotary switch, reliable seal and long service life. It is widely used in water supply and drainage of water plants, power plants, steel plants, papermaking, chemical, catering and other systems. And deadline use.
    Features of D671X Pneumatic Wafer Type Soft Seal Butterfly Valve
    1. The valve adopts the center line structure, which has a tighter sealing function as it closes, and the sealing performance is reliable.
    2. The sealing sub-material is made of stainless steel and nitrile oil-resistant rubber, which has a long service life.
    3. The rubber sealing ring can be located on the valve body or on the butterfly plate. It can be used for different characteristics of the media for users to choose.
    4. The butterfly board adopts a frame structure, which has high strength, large flow area and small flow resistance.
    5. The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing valve seat sealing material is replaced.
    6. The valve has a two-way sealing function. It is not controlled by the flow direction of the medium and is not affected by the space position during installation. It can be installed in any direction.
    7. The valve is unique in structure, flexible in operation, labor-saving and convenient.
