In chemical processes, it is often necessary to adjust the valve opening in order to control the pressure before the valve; for example, this is used for controlling tower pressure. So how can this be achieved in Pro2? Can a feedback controller be used for this purpose?

Using CONTROLLER for logical control yields the same result. HYSYS is better in terms of dynamic control

It is not possible to control the valve opening degree in pro11.
