Problem Statement
Is it possible to specify the "Cv" value and determine the pressure drop across the control valve?
Solution
If you are able to obtain or estimate the Cv of the meter then you can specify this Cv value in a control valve in HYSYS from the Rating/Sizing tab.
In the valve Design/Parameters page there is a check box - "Use sizing methods to calculate Delta P". The valve can calculate pressure drop with specified Cv even in the steady state simulation. This will be an approximation for the pressure drop calculations.
