I find this pdf to be very helpful. I printed it and put it into my binder.
https://www.cedengineering.com/userfiles/Control Valves Basics - Sizing & Selection.pdf

Types of questions you might get:
1. Calculating Cv for a certain system 
2. Selecting a valve for a particular application using Cv
3. Something about the difference between quick opening, linear, and equal percentage valves (Selecting a particular type from the Cv% - Valve opening % chart for given flow characteristics)
4. Calculating a valve rangeability
5. Identifying a certain valve from a PID diagram

Are you asking for basic control valve sizing literature?  If so, just google "Fisher Control Valve Sourcebook".

You could check out Crane TP-410.

Yes.  Crane tp-410 is a very good reference to have after the exam too.
