    所屬類別:Butterfly Series

    Summary
    Electric high performance control, cut off valve is long life, energy saving type butterfly valve multi-level seal. The structure of the principle of three-dimensional design, seat with hierarchical structure, soft and hard sealing compatible processing skills, advanced technology. This product is composed of a valve body, a butterfly plate, valve seat, stem, multi-level transmission mechanism and other main components. So it is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas pipelines and water supply and drainage and other corrosive medium..
    Characteristic
    This series of butterfly valve uses is the design principle of three-dimensional eccentric, make the space motion of the sealing surface of the ideal, no friction between the sealing surface, no interference, and sealing materials are selected properly, so that the valve sealing performance, corrosion resistance, high temperature resistance and wear resistance has been a reliable guarantee. Its main features are as follows:
    1, the opening torque is small, flexible and convenient, labor-saving and energy-saving.
    2, three-dimensional woven structure, make the disc more closed more tightly, and the sealing performance is reliable, can achieve no leakage.
    3, high pressure resistance, corrosion resistance, abrasion resistance, long service life etc..
