Product Use

The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with a rotation angle between 0° and 90°. When rotated to 90°, the valve is fully open. This type of valve should generally be installed horizontally in the pipeline. Soft seal butterfly valves can be divided into flanged soft seal butterfly valves and wafer-type soft seal butterfly valves according to their connection methods.

Butterfly valve

The disc of a soft-sealed butterfly valve is installed in the diameter direction of the pipe. Within the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around its axis, with a rotation angle between 0° and 90°. When rotated to 90°, the valve is fully open. This type of valve should generally be installed horizontally in the pipeline.
