Hello Drexl and stanier!
I see that the Fisher handbook actually defines a control valve with what we in Europe normally would call a regulating valve.
If then your question is valid for all types of control/regulating valve constructions, all sizes, all pressure classes, all fluids etc, I would go straight for staniers answer:
You will always have to select a control valve from the flow (lower, average and max), fluid type, pressure (and delta p) and necessary response time.
I could also add that for most 'common' applications you would probably find special valves adapted to regulate from 90-95% opening down to 10-5% opening, if it is suited for the flow conditions you have.
Some specialized control valves will regulate from 2-5% opening (needed to be free from the seat) and up to (almost) full opening.
Quite another thing is if you can utilize the full control range of the valve! For butterfly valves, in a typical application, often only a smaller part of the range (say 20% of the opening range) will actually be used.
My advice is like staniers: put your efforts into finding the requirements and actual flow, and regulating parameters. Quite often this is neglected or overseen or not given enough engineering thought, ending up with wrongly selected control valves, often both type and size.
With correct information, any good supplier of control valves would be able to help you.
If anything goes wrong with a control application, uneven regulation, breakdown or eccessive wear or noise, you can be 100% sure that engineering/selecting and/or installation is not done properly.
Any selection of a control valve should include full analysis of flow, delta p and cavitation curve under all actual flow conditions. (And if your supplier cannot give you this, drop the supplier and find one better!)
PS: regulating speed is very often set too fast in a regulating circuit, giving undamped swingings and killing valves and actuators.
