During valve sizing from all calculation you got flow
coefficient CV 12,than what it means? like for selecting
pressure transmitter if your MAWP is 12 bar than you select
a capsule of max. 20 bar which cover your mawp 12 in same
way for selecting control valve If CV is 12 than how we use
it in selecting valve??????

Go to the valve manufacturer's manual and select a valve
with the next bigger cv that the one you calculated.
Good luck
