    What is a metal seat wafer butterfly valve?

    Stainless steel hard seal wafer butterfly valve is a simple structure of the regulator, and it can also be used for switch control of low pressure pipeline medium. It refers to the closing part for the disc, which revolves around the valve shaft to achieve the opening and closing of a valve. It mainly plays a cutting and throttling role in the pipeline. The opening and closing component is a disc that rotates around its own axis in the body to achieve the purpose of opening and closing or adjusting.

    Advantages of the metal seat wafer butterfly valve:

    1.Labor saving in operation
    When the sealing surface of the disc is closed, the force is uniform and the bearing capacity is high. In the opening process of the disc, each point of the sealing surface completes the action of disconnecting from the sealing surface of the seat at the same time, no squeezing phenomenon, basically no friction, and minimal opening torque.
    2.Good corrosion resistance
    The sealing ring is made of stainless steel, with double advantages of metal hard seal and elastic seal. In the case of low and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics.
    3.Large size disc
    Large size disc adopts truss structure. It has the advantages of high strength, large flow area and small flow resistance.
    4.0 leakage
    The sealing parts can be replaced, the sealing is reliable to achieve bidirectional sealing, and the gas test leakage is zero.
