Flange Fluorine-lined Butterfly Valve
Product use
Flange fluorine lined butterfly valve is widely used for the transportation of liquid and gas (including steam) in various types of industrial pipelines, especially for the application of severely corrosive media, such as hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
Product features
1. Small volume and convenient installation
2. The center line butterfly valve is concentric (center line) between the whole butterfly plate and the valve seat within the circumference of 360 ℃, with two-way sealing function, and the pressure and flow can be adjusted freely;
3. Four stage loading elastic seal absolutely ensures zero leakage inside and outside the valve.
