The main structural features of this series of butterfly valves are wafer type and flange type triple eccentric sealing. The valve seat sealing ring adopts two structures: elastic sealing and soft and hard compatible multi-level sealing. Its sealing performance is reliable and ensures that When opening, the disc does not contact the sealing seat, which eliminates the uneven load of the sealing seat, prolongs the service life, ensures reliable sealing performance, and has the advantages of high temperature resistance, wear resistance and corrosion resistance.
