Germany KSB Wafer soft seal butterfly valve, KSB BOAX-B manual butterfly with a simple structure, flow resistance coefficient, linear flow characteristics tend not stuck debris. And light weight, easy installation, the drive torque is small advantages. This valve is used only for cutting the media, but also for regulating the flow of media use. Driving device according to user requirements, respectively, can be manual, electric, pneumatic and other means. Selection of parts of different materials, equipped with seals of different materials can be adapted to different media, working conditions, so that the cost and performance to achieve the best results. BOAX-B soft seal butterfly valve for temperature ≤120 ℃ Nominal ≤1.6MPa drainage, sewage, food, heating, gas, shipbuilding, water and electricity, metallurgy, energy systems, and textile and other industries, especially for bi-directional sealing and body easily corroded occasions, for regulating the flow and the closure media. BOAX-B butterfly valve using synthetic rubber, for a variety of industrial applications. Turbine with a handle or manual, pneumatic or electric actuators. Semi-ear style body (T2), full-ear type body (T4) with convex flange, pressure PN 10/16.
