Manual fluorine-lined butterfly valve

Overview:

Manual fluorine-lined butterfly valves are available in flange and wafer connection methods, which can be selected according to the on-site working conditions. They are mainly used in corrosive media and can serve as switches or pneumatic actuators with positioners to regulate the pressure and flow of the medium. The pneumatic fluorine-lined butterfly valve is lined with thick high-molecular materials on the flow-through components, valve body, butterfly plate and valve stem by lining technology. It has excellent anti-corrosion performance and can be applied to any concentration of concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, alternating acid and alkali and other corrosive media.
