KOSO valve positioner (DN) and pipe diameter size table
It is well known that the size of the valve has an inevitable connection with the size of the pipeline. Generally, how large the pipe diameter (outer diameter) is equipped with a same valve. The valve size needs to be calculated based on the actual parameters. Generally speaking, the pipeline will be larger. The valve is actually relatively small. It mainly depends on the amount of flow that the valve location needs to be controlled, and the size of the pipeline only needs enough circulation capacity.
