Pneumatic fluorine lined butterfly valve 9 features:

    1, small and light, easy to disassemble and repair, and can be installed in any position.

    2, simple structure, compact, small operating torque, 90° rotation open quickly.

    3, the flow characteristics tend to be straight, good adjustment performance.

    4, the connection between the butterfly plate and the valve stem adopts a pin-free structure to overcome the possible internal leakage point.

    5, the butterfly plate can be sprayed according to user requirements, such as nylon or polytetrafluoroides.

    6, the valve can be designed to flange connection and clamp connection.

    7, the driving mode can be selected manual, electric or pneumatic.

    8, the seal can be replaced, and the sealing is reliable to achieve two-way sealing.

    9, the outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and extends the service life of the valve, and maintains zero leakage with pressure opening and closing more than 50,000 times.

    At present, pneumatic butterfly valves are used more and more in low pressure medium and large diameter pipelines. Pneumatic butterfly valve can be divided into: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve and so on.

Pneumatic fluorine lined butterfly valve uses and features:

    Butterfly valve with spherical sealing surface lined with polytetrafluoroethylene butterfly plate, the valve is easy to operate, tight sealing performance, long service life; Can be used to quickly cut off or adjust the flow. Suitable for applications requiring reliable sealing and good conditioning characteristics. The valve body adopts split type, and the sealing at both ends of the valve shaft is controlled by fluorinated rubber on the rotating base between the butterfly plate and the valve seat. Ensure that the valve shaft is not in contact with the fluid medium in the cavity. It is widely used for the transportation of liquids and gases (including vapors) in various types of industrial pipelines, and for the use of severely corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia and other highly corrosive media. Its main features are:

    1, novel design, reasonable, unique structure, light weight, fast opening and closing.

    2, small torque, easy to operate, labor-saving dexterity.

    3, can be installed in any position, easy maintenance.

    4, the seal can be replaced, the sealing performance is reliable to achieve bi-directional sealing zero leakage.

    5, sealing material aging resistance, corrosion resistance, long service life and other characteristics.
