Working Principles

未标题-1

The butterfly disk is installed in the diameter direction of the pipeline. When the butterfly valve in the pipeline, the disk rotates around the axis line, and the rotation angle range is between 0-90 degree. When the valve does not rotate at 0 degree, the valve disk is closed. When the valve rotates to 90 degree, the valve disk is opened absolutely.
