    Double Disc Wafer Check Valve

    We offer double disc wafer check valve products made from bronze, carbon steel, stainless steel, and other special casting alloys.
    The double disc wafer check valve features a single-piece cast valve body with no pin retainer holes on the valve body. The design minimizes potential leakage through the valve body, making it the preferred choice for applications involving highly toxic, corrosive, or hazardous gas chemical processing.

    Applications

    Double disc wafer check valves can be used in water conveyance systems, sewage treatment pipeline systems, flue gas handling systems, seawater pipeline systems and so on.
