The fluorine-lined plug valve is a valve that uses a plug body with a through hole as the opening and closing part, and the plug body rotates with the valve stem to realize the opening and closing action. The plug valve opens and closes quickly and has low fluid resistance. Since the movement between the sealing surfaces of the plug valve has a wiping effect, and it can completely prevent contact with the flowing medium when fully open, it can usually be used for media with suspended particles. In recent years, as one of the earliest valves adopted by people in history, it has not only not been replaced by valves such as lined ball valves, but has become more and more popular in the market. Plug valves are mostly used to cut off the flow of media, and can also be used for media distribution (three-way plug valve). This product is widely used in any corrosive media except "molten alkali metals and elemental fluorine", and is widely used in chemical, petroleum, medicine, food, steel smelting, papermaking, hydropower, environmental assurance and other industries.
