Maximum differential pressure Higher differential pressures across the valve are compensated for automatical- ly by this. Motion of the closing element in the direction of the closing point causes an increase in the pressure drop across the valve. This ensures a cons- tant water quantity. The permitted maximum differential pressure is specified in the data sheet.Sizing with missing hydronic dataIf no hydronic data are available, then the same valve DN can be selected as the nominal diameter of the heat exchanger.Flow characteristicsIn the case of an electronic pressure-independent characterised control valve, the actuation signal requirement corresponds directly to a flow value. Alterna- tively, the control functions power control and position control are available.Settings
