operational principle

Manual butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to open, close, and regulate the fluid channel. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the sanitary 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.
