D641F4 D641F4-10 D641F4-10C D641F4-10P Pneumatic lined butterfly valve

Overview of D641F4 D641F4-10 D641F4-10C D641F4-10P Pneumatic lined butterfly valve

D641F4 D641F4-10 D641F4-10C D641F4-10P Pneumatic lined butterfly valve adopts PTFE lined butterfly plate with spherical sealing surface. The valve has light operation, tight sealing performance and long service life; It can be used to quickly cut off or adjust the flow. It 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 fluororubber on the rotating base surface between the butterfly plate and the valve seat; The valve shaft is not in contact with the fluid medium in the cavity. It is widely applicable to the transportation of liquid and gas (including steam) in various types of industrial pipelines and the use of severely corrosive media, such as sulfuric acid, phosphoric acid, strong alkali, aqua regia and other highly corrosive media.
