ABSTRACT:
A hydraulic system for a work machine is disclosed. The hydraulic system has a source of pressurized fluid and a fluid actuator with a first chamber and a second chamber. The hydraulic system also has a first valve configured to selectively fluidly communicate the source with the first chamber and a second valve configured to selectively fluidly communicate the source with the second chamber. The hydraulic system further has a proportional pressure compensating valve configured to control a pressure of a fluid directed between the source and the first and second valves.
