Butterfly valve size and pipe size comparison table

As we all know, there is an inevitable connection between the diameter of the butterfly valve and the size of the pipeline. Generally speaking, the diameter (outer diameter) matches the butterfly valve. Butterfly valve diameter needs to be calculated according to the actual parameters. Generally speaking, the pipeline will be larger, but the actual valve will be smaller, which mainly depends on the flow rate to be controlled by the valve position, while the pipeline size only needs to have enough circulation capacity.
