I'm interested to know if anyone is familiar with a method for determining, quantitatively, a controllability index for a control valve recognizing that influence quantities such as pressure drop would be a major contributor. Qualitatively, there are "rules of thumb" such as 15 to 25% of the friction loss in a system should be available for the valve.
