    Product Description

    1. Concentric Rubber Lined Resilient Seated Flange Type Butterfly Valve comes with integral flanges and does not rely on pipeline flanges for clamping.

    2. The valve body cavity is fully rubber lined, and concentric disc presses against lining to achieve bidirectional resilient sealing.

    3. Flanged connection offers high strength, suitable for working conditions with vibration and large pressure fluctuation.

    4. Widely applied in pump stations, water supply and drainage, sewage treatment and general chemical fixed pipelines.

    Features & Benefits

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

    2. Bidirectional zero leakage resilient sealing.

    3. Rubber lining resists moderate acid and alkali corrosion.

    4. Concentric structure provides low torque for easy operation.

    5. Flanged connection has high reliability, suitable for buried or vibrating pipelines.

    6. Available for on off and modulating service.
