The PTFE-lined butterfly valve features a PTFE-lined disc with a spherical sealing surface. This valve offers easy operation, tight sealing, and an exceptionally long service life. It can be used for quick shutoff or flow regulation.
It is suitable for applications requiring reliable sealing and excellent regulating characteristics.
The valve body is a split-piece design, with the seals on both ends of the valve shaft controlled by a fluororubber-coated rotating surface between the disc and seat, ensuring that the valve shaft is isolated from the fluid.
It is widely applicable for conveying liquids and gases (including steam) in various types of industrial pipelines, and for applications involving highly corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, and strong alkalis.
