INTRODUCTIN:

The rubber-lined butterfly valve uses a PTFE-lined butterfly plate with a spherical sealing surface. The valve is easy to operate, tightly sealed, and has a long service life. It can be used to quickly cut off or adjust the flow rate. 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 the rotating base surface between the butterfly plate and the valve seat with fluorine rubber; ensure that the valve shaft does not contact the fluid medium in the cavity. Widely applicable to the transportation of liquids and gases (including steam) in various types of industrial pipelines, and the use of severely corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, etc. have strong corrosion Sexual medium.
