Typical design institutes and control valve manufacturers have calculation software; manual calculations are very cumbersome.

The process systems team specifies the operating parameters, while the instrumentation team calculates the Cv value based on these parameters (or the manufacturer carries out this calculation), and then selects a valve with the appropriate diameter using this CV value.
