Abstract: An exemplary hydraulic system includes a digital valve operable to fluidly connect a hydraulic load to a pressure supply. A digital controller is operably connected to the digital valve. The digital controller stores a target value of a hydraulic system operating parameter and is configured to formulate a pulse width modulated control signal based on the target value. The digital controller transmits the control signal to the digital valve for controlling the operation of the valve.

Abstract: An exemplary hydraulic system includes a first digital valve fluidly connectable to a first hydraulic load and a pump. The first valve is operable to fluidly connect the first hydraulic load to the pump. A second digital valve is fluidly connectable to a second hydraulic load and the pump. The second valve is operable to fluidly connect the second hydraulic load to the pump. The system includes a first sensor for detecting a pump discharge pressure and a second sensor for detecting an inlet pressure of the first hydraulic load. A controller is configured to determine a time delay based on the pump discharge pressure and the first hydraulic load inlet pressure and to send a control signal instructing the second valve to commence opening at a time substantially equal to the time delay after commencing closing the first valve.
