Overview of pneumatic lined fluorine butterfly valve: The pneumatic fluorine-lined butterfly valve adopts a PTFE-lined butterfly plate with a spherical sealing surface. The valve is easy to operate, tightly sealed, and has a long service life; it can be used to quickly cut off or adjust the flow. Suitable for occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts a split type, and the sealing at both ends of the valve shaft is controlled by the rotating base surface between the butterfly plate and the valve seat and fluorine rubber to ensure that the valve shaft does not contact the fluid medium in the cavity.

10Pneumatic fluorine-lined butterfly valve
It is widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, and the use of severe corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali and other highly corrosive media .
Pneumatic fluorine-lined butterfly valve structure characteristics:
①Small size, light weight, light operation, easy to install and maintain.
②Excellent and reliable sealing performance, zero leakage, and long service life.
③The flow characteristics tend to be straight, and the regulation performance is the best.
④Simple structure, quick opening and closing, 90°rotating opening and closing.
⑤It can be used in place of various valves such as gate valve, stop valve, plug valve, hose valve and diaphragm valve.
⑥ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
⑦The lining material of replacement parts can be applied to various media.
