    Product Description

    1. Concentric Fluoroplastic Lined Resilient Seated Flange Type Butterfly Valve comes with integral flanges and fluoroplastic lining inside valve body.

    2. Concentric disc presses against fluoroplastic lining to achieve bidirectional resilient sealing for strongly corrosive chemical media.

    3. Flanged connection bears pipeline load, suitable for pressure fluctuation and vibration working conditions.

    4. Applied in strongly corrosive process pipelines for chemical, pharmaceutical and pickling industries.

    Features & Benefits

    1. Integral flanges independently bear pipeline load, installation and removal do not depend on pipes on both sides.

    2. PFA/PTFE fluoroplastic lining resists strong acid, strong alkali and strong oxidants.

    3. Bidirectional zero leakage resilient sealing.

    4. Short face to face dimension saves installation space.

    5. Concentric design delivers moderate operating torque compatible with various actuators.

    6. Medium only contacts fluoroplastic layer, offering better chemical resistance than ordinary rubber lined butterfly valves.

    7. Suitable for on off and slight modulating service.
