  • DESCRIPTION

    Applications of electric triple eccentric butterfly valve:

     

    Electric triple eccentric butterfly valve has the dual advantages of metal sealing and elastic sealing. It has excellent sealing performance no matter under low or high temperature conditions, and is also widely used in some high temperature, high pressure, strong corrosion and other fields. It is mainly used in petroleum, Chemical industry, electric power, metallurgy, steel, papermaking, medicine, food, textile, light industry and other industries.
     

    Performance characteristics of electric triple eccentric butterfly valve:

     

    1. There are electric wafer-type triple eccentric butterfly valves and electric flange triple eccentric butterfly valves, which can meet the needs of pipelines with different connection methods.

    2. The sealing performance is reliable and the service life is long. It adopts a three-dimensional eccentric structure and there is very little friction between the butterfly valve and the valve body when opening and closing.

    3. Using different valve body materials and sealing rings, it can be applied to various media such as different temperatures, pressure levels, and corrosion resistance;

    4. The triple eccentric structure has a sealing function that becomes tighter as it is closed, and is flexible in operation and is not affected by high or low pressure of the medium.
    5. The electric triple-eccentric butterfly valve can adjust the butterfly plate sealing ring to move closer to the valve seat, restoring the original sealing performance and greatly improving the service life.
