    Overview of D343H hard seal three eccentric butterfly valve:

    D343W hard seal triple eccentric butterfly valve series is a long-life and energy-saving butterfly valve. The structure adopts the three-dimensional eccentric principle design, and the elastic seal and soft and hard multi-layer seal are compatible with the new processing technology, so that the torque force of the butterfly valve can be reduced during operation, so as to save labor and energy. So as to ensure the overall corrosion resistance, high temperature resistance and damage resistance. It is suitable for food, medicine, petrochemical industry, power plant, steel plant, industrial environment, water treatment and high-rise buildings. It is used to regulate flow and intercept fluid water supply and drainage pipelines.

    D343H hard seal three eccentric butterfly valve features:

    1. The flange type metal hard seal butterfly valve adopts a three eccentric sealing structure, with almost no wear between the valve seat and the butterfly plate, and has the sealing function of closing more and more tightly

    2. The sealing ring of butterfly valve is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life under low and high temperature

    3. The sealing surface of butterfly plate adopts surfacing cobalt based cemented carbide, which is wear-resistant and has long service life

    4. Large size butterfly plate adopts quilted frame structure, with high strength, large overflow area and small flow resistance

    5. The metal hard sealing butterfly valve has the function of two-way sealing. It can be installed in any direction without the restriction of medium flow direction and the influence of space position

    6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °), which is convenient for users.
