1. High strength of valve body. Large safety coefficient, able to resist very large pipeline pressure. High strength of valve body. High safety coefficient, able to resist great pipeline pressure.
2. The valve seat adopts the structural form of overall vulcanisation on the valve body and extends to the outer edge of the valve body, which eliminates the use of flange gasket, and the seat of sulphur is strong and reliable, eliminating leakage paths and corrosion gaps.
3. Soft sealing centreline double flange butterfly valve can achieve 100% bidirectional switching function. It can be used in various fields of industry, especially in shipbuilding, embankment, petrochemical, heavy industry, seawater, tap water, sewage and other large pipe networks. -
