pneumatic fluorine ball valve ZSHOF is the use of pneumatic actuators and fluorine ball valve, valve with fluorine plastic as the inner lining, and matched with rod sphere structure model, its unique elastic lip seal seat structure plus, it has the advantages of an ordinary ball valve, high sealing performance and low operating torque at high pressure and high temperature range. Pneumatic fluorine ball valve can be used for switching or adjustment, conveying corrosion pneumatic ball valve is suitable for liquid and gas pipeline in various industrial (including steam), can work well in all kinds of acid, alkali, salt and other corrosive media. Full bore pneumatic fluorine ball valve to provide maximum flow, and can be used for pipeline purging, cleaning or quarantine transmission.
Corrosion resistance of pneumatic ball valve is widely used in various types of industrial liquid and gas pipeline (including steam) delivery, especially with severe corrosive media occasions, such as: sulfuric acid, hydrofluoric acid, phosphoric acid medium, chlorine, alkali, aqua regia and other strong corrosive.
