D671f pneumatic butterfly valveUsing PTFE lined butterfly plates with spherical sealing surfaces, the valve is easy to operate, has tight sealing performance, and has a long service life; Can be used to quickly cut off or adjust flow. Pneumatic valves are suitable for applications that require reliable sealing and good regulating characteristics. The valve body adopts a split type design, and the sealing at both ends of the valve shaft is controlled by adding fluororubber to the rotating base surface between the butterfly plate and the valve seat; Ensure that the valve shaft does not come into contact with the fluid medium inside the chamber.

D671f pneumatic butterfly valveWidely applicable to the transportation of liquids and gases in various types of industrial pipelines, and in applications with severe corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, etc.

D671f pneumatic butterfly valveThe main features are:
