Wafer type metal hard sealing butterfly valve

Wafer type metal hard sealing butterfly valve

This product is composed of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure adopts the three-dimensional eccentric principle design, and the new processing technology compatible with the elastic seal and the hard and soft multi-layer seal makes the butterfly valve reduce its torque during operation and achieve the function of labor saving and energy saving. So as to ensure the overall corrosion resistance. High temperature resistance. Damage -resistant reliability.

Main performance characteristics

  1. Reasonable structure, small and lightweight, flexible operation, labor-saving and convenient;
  2. Reliable sealing, which can achieve air sealing without leakage;
  3. Flow characteristics tend to be linear and have good adjustment The best;
  4. The principle of triple eccentricity is adopted, so that the sealing surface is nearly zero and the service life of the valve is prolonged;
  5. The application range is wide. Such as: can be used for water, steam , oil, air, gas and other media.
  6. It is suitable for various medium pipelines such as different temperatures and pressure levels below 6.4MPa, corrosion resistance and so on.

Application of electric flange type hard sealing butterfly valve

This butterfly valve is suitable for food, medicine, petrochemical, power plants, steel mills, industrial environmental protection water treatment and high-rise buildings, water supply and drainage pipelines as devices for regulating flow and shutting off fluids.
