overview the
at pneumatic float ball valve can be used for switching or adjustment. the full bore pneumatic float ball valve provides maximum flow and can be used for sweeping or isolating the conveying pipe. it is widely used in a variety of different the transport of liquids and gases (including steam) in industrial pipelines, especially those with severe corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, and aqua regia, etc.
i. pneumatic float ball valve product overview
pneumatic float ball valve is composed of double (single) acting pneumatic piston actuator and fluorine ball valve. it is powered by compressed air, and the valve stem drives the valve core to rotate 90° in the valve body. the valve adopts fluoroplastic as the inner lining, and is matched with a new type of rod-ball structure, coupled with its unique elastic lip seal seat structure, which has the advantages of common fluorine-filled ball valve, and can be used in large pressure differentials and high sealing performance and low operating torque over a wide temperature variation range.
pneumatic-lined ball valve can be used for switching or regulating. full-diameter pneumatic-lined fluorine ball valve can provide maximum flow, and can be used to sweep or isolate pipelines. it is widely used in liquid and gas of various types of industrial pipelines. (including steam) transportation, especially for occasions with severe corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
