product description
Wafer-type fluorine-lined butterfly valve adopts PTFE-lined butterfly plate with spherical sealing surface and silicone rubber gasket at the base of valve seat to adjust the sealing performance of the valve; The fluorine-lined butterfly valve has light operation, tight sealing performance and long service life; It can be used to cut off or adjust the flow quickly. Fluorine-lined butterfly valve is suitable for occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts split type, and the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base between the butterfly plate and the valve seat; Thereby achieving compact product structure, beautiful appearance, reasonable process and reliable performance. Ensure that the valve shaft does not contact with the fluid medium in the cavity, and it is very convenient to replace the valve shaft, and the valve can be completed without detaching the pipeline. Fluorine-lined butterfly valves are widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, especially in the use occasions with severe corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
