Abstract
An arrangement for operating a hydraulic consumer including a hydraulic control valve having a main slide valve defining a hydraulic volume flow in the direction of hydraulic connections provided for operation of the hydraulic consumer, a pressure compensation valve and an orifice, the pressure compensation valve controlled on the basis of a pressure difference that drops at the orifice when the volume flow passes through, such that the pressure compensation valve adopts an at least partially closing control position when the hydraulic pressure upstream of the orifice in the direction of the volume flow is greater than downstream of the orifice, including a restoring spring force of a spring element preloading the pressure compensation valve into a fully open position, and a sensor arrangement sensing the pressure difference and transmitting a pressure difference value derived therefrom to a control unit evaluating the pressure difference value.
