When the DPCV is applied across a balance valve (BV), the flow through the balance valve remains constant even if the pressure difference across the BV-DPCV combination changes. This might be useful in specfic situations in which the hydraulic system balance must be assured in partial load working conditions.
If the differential pressure across a control valve is maintained constant by means of a DPCV, the control valves authority is theoretically 1 and completely insensitive to hydraulic interactivity. This way the control performance
of the respective control loop might be increased.
