DN Fluorine-butterfly butterfly valve

Main Uses
Fluorine-lined butterfly valves are suitable for many different types of pipelines, such as: petroleum, chemical, metallurgy, hydropower and many other fields. Especially for the occasions with highly corrosive media, such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia and other highly corrosive media.

Features
1. Fluorine-lined butterfly valve adopts the butterfly plate which rotates together as the opening and closing parts to realize the opening, closing and adjustment of the valve.
2. The valve body of the fluorine-lined butterfly valve adopts a split combination, which is convenient for assembly and sealing adjustment. When the valve is working, only the perfluoroplastic seat and the fluorine-lined plastic butterfly plate are in contact with the medium. The medium contact surface is completely isolated with PTFE, which can prevent metal parts from being corroded.
3. The inner surface of the valve body passage is smooth, and the service life of the valve is longer.
