RE: control valve size
By avoiding rules of thumb and applying more mental energy than pumping energy it is often possible to get away with less than 30% across the valve. And in many applications in the industries where I work the control valves are being eliminated completely and are being replaced by variable speed drives on the motors. In the end everything is driven by economics, and the economics have changed over the last 40 years - and continue to change.

RE: control valve size
Rconner is correct in terms of reduced port ball valves and gate valves / plug valves, but nearly all control valves are not piggable regardless of the size.
