Abstract: The present invention relates to an actuator (3) for regulating a valve (1) in a fluid system, wherein the actuator (3) is adapted to operate according to a characteristic curve (4) containing information correlating a valve opening with a flow through the valve (1) and to a flow rate measured by a flow measuring device (5), characterized in that, the regulation of the valve (1) is based on a modified characteristic curve (4M) that is based on a basic characteristic curve (4B) and the measured flow rate by the flow measuring device (5) compared to a design flow rate. The present invention further relates to the method of controlling the valve.
