Fully-Weld 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.
