Pneumatic Operated Wafer Type Fluorine Lined Butterfly Valve with worm gear

It is suitable for occasions requiring reliable sealing and good regulation characteristics. The valve body adopts the split type, and the sealing at the present end of the valve shaft is controlled by adding fluoro rubber to the rotating base surface between the butterfly plate and the valve seat, so as to achieve compact product structure, beautiful appearance, reasonable process and reliable performance. To ensure that the valve shaft does not contact with the fluid medium in the cavity, it is very convenient to replace the valve shaft, and the valve can be completed without detaching the pipeline. The products are widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, especially in the use of corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus, acid, chlorine, strong alkali, aqua regia and other media with strong corrosion
