Product overview of Q641F pneumatic lined fluorine regulating ball valve
The Q641F pneumatic fluorine-lined regulating ball valve is composed of a pneumatic actuator and a fluorine-lined ball valve. The valve is lined with fluorine plastic, and is equipped with a new type of ball structure with rod, plus its unique elastic lip seal seat structure. It has the advantages of ordinary ball valves, and can have high sealing performance and low operating torque within a large pressure difference and a large temperature difference range. Pneumatic fluorine-lined ball valve can be used for switching or adjustment. Corrosion-resistant pneumatic ball valve is suitable for the transportation of liquid and gas (including steam) in various industrial pipelines. It can be used in various acids, alkalis, salts and other strong corrosive media. Works well. The full-bore pneumatic fluorine-lined ball valve provides the largest flow rate and can be used for line sweeping cleaning or isolating pipelines.
Corrosion-resistant pneumatic ball valves are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of severely corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, Strong corrosive media such as aqua regia.
