Fluorine lined butterfly valve pneumatic fluorine lined butterfly valve principle:

The pneumatic fluorine lined butterfly valve adopts PTFE lined butterfly plate with spherical sealing surface. The valve is easy to operate, with tight sealing performance and long service life; It can be used to quickly cut off or regulate the flow. Pneumatic valves are suitable for applications requiring reliable sealing and good regulating characteristics. The valve body is of split type, and the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat; Ensure that the valve shaft does not contact with the fluid medium in the cavity. It is widely applicable to the transportation of liquids and gases in various types of industrial pipelines and the use of highly corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
