The structure of electric hard seal butterfly valve D941,D971 adopts the three-dimensional braided core principle design, and the valve seat adopts the multi-level structure compatible with hard and soft seal. It consists of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other major components. Due to the design of three-dimensional eccentric principle, the spatial movement trajectory of the sealing surface is idealized; there is no friction and interference between the sealing surfaces. Coupled with the proper choice of sealing materials, the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are thus reliably guaranteed.
