  • Product Description
  • Detailed parameters
  • Sediment-proof flanged butterfly valve is a new product developed by our company on the basis of double eccentric flanged butterfly valve, which is aimed at the pipeline system with large sediment, the valve axial seal is easy to fail and the service life is short.

    Features:

    1. The butterfly valve has the advantages of double eccentric flange butterfly valve.

    2, the use of anti-sediment sealing structure, to ensure that the axial leakage, stainless corrosion, not stuck dead and other phenomena, to extend the service life of the valve.

    Sediment type flange butterfly valve use: in petrochemical, food, medicine, textile, papermaking, water and electricity, ships, water supply and drainage and other corrosive, non-corrosive medium pipeline, as a cut-off and throttling, more suitable for high sediment content in the Yellow River Basin irrigation station pipeline.

    ① The unique design of the three-way eccentric makes the friction-free transmission between the sealing surfaces and prolongs the service life of the valve.

    ② The elastic seal is generated by the torque.

    The ingenious wedge design so that the valve has the more closed the more tight automatic sealing function, the sealing surface between the compensation, zero leakage.

    ④ small size, light weight, light operation, easy to install.

    ⑤ pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

    The replacement parts material can be applied to a variety of media, and can be lining anti-corrosion (lining F46, GXPP, PO, etc.).

    ⑦ Continuous structure diversification: on-clamp, flange, butt welding.

    The butterfly plate of the anti-sediment flanged butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 °-90 °. When rotating to 90 °, the valve is fully open.
