The turbine flange soft seal butterfly valve has the advantages of simple structure, small flow resistance coefficient, linear flow characteristics, no debris retention, light weight, convenient installation and small driving torque. The valve can be used not only to cut off the medium, but also to adjust the flow of the medium. Parts of different materials and sealing rings of different materials can adapt to different media and working conditions to achieve the best cost and performance. Turbine flange soft sealing butterfly valve is widely used in water supply and drainage, sewage, food, heating, gas, shipping, hydropower, metallurgy, energy system, light textile and other industries with temperature ≤ 120 ℃ and nominal pressure ≤ 1.6Mpa, It is especially suitable for two-way sealing and occasions where the valve body is easy to rust. It can be used as flow regulating and intercepting medium.
