Ventilation Butterfly Valve

Triple Eccentric butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0 ° ~ 90 °, and when the rotation reaches 90 °, the valve is fully open. Features of the new high life stainless steel butterfly valve and problems with the butterfly valve during use. widely used in metallurgy, electric power, petrochemical, water supply and drainage and municipal construction and other industrial pipelines with medium temperature ≤ 425 °C for regulating flow and cutting off fluids.

Features

  1. The butterfly valve adopts three eccentric hard seal structure, seat and plate are almost wear-free
  2. The dual advantages of metal hard seal and elastic seal, have excellent sealing performance in low temperature and high temperature, corrosion resistance, long service life and other characteristics.
  3. Valve disc overlays HF, which is wear-resistant and has a long service life
