Selection of cut-off valves

I would like to ask: when selecting a cut-off valve, what is the purpose of entering the parameter related to the medium flow rate? In other words, why is it necessary to have this parameter? Because the flow rate in the pipeline where the valve is located is already fixed, and when selecting a shut-off valve, there is no need to consider factors such as diameter reduction like with control valves.

It’s used to calculate the pressure difference ratio before and after the valve, right?

Choose the type of valve based on the flow capacity and volume of flow
