ZSHOF pneumatic fluorine lined ball valve is composed of pneumatic actuator and fluorine lined ball valve. The valve is lined with fluoroplastic and equipped with a new rod ball structure. In addition, its unique elastic lip seal seat structure gives it the advantages of ordinary ball valves, which can have high sealing performance and low operating torque in large pressure and temperature difference ranges. Pneumatic fluorine lined ball valves can be used as switches or regulators. Corrosion resistant pneumatic ball valves are suitable for the transportation of liquids and gases (including steam) in various industrial pipelines, and can work well in strong corrosive media such as acids, alkalis, salts, etc. The full bore pneumatic fluorine lined ball valve provides a large flow rate and can be used for cleaning or isolating pipelines during transportation.
Corrosion resistant pneumatic ball valves are widely used for the transportation of liquids and gases (including vapors) in various types of industrial pipelines, especially in applications with highly corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, and other highly corrosive media.
