Zusammenfassung:	An exemplary hydraulic system includes a plurality of digital valves, each valve fluidly connectable to a corresponding hydraulic load. The digitals valves are operable to fluidly connect the corresponding hydraulic load to a pressure source. The hydraulic system further includes a digital controller operably connected to the plurality of digital valves. The digital controller is configured to assign a priority level so that it is associated with each of a plurality of hydraulic loads, and to formulate a pulse width modulated control signal based on the assigned priority levels. The digital controller transmits the control signal to the plurality of digital valves for controlling the operation of the valves.
