Abstract: The present document relates to a hydraulic system having a first hydraulic pump, a second hydraulic pump, at least one hydraulic actuator, a low-pressure tank, and a pressure controlled flow compensating valve. A high-pressure port of the first hydraulic pump and a high-pressure port of the second hydraulic pump are fluidly connected or fluidly connectable to the at least one hydraulic actuator. The high-pressure port of the second hydraulic pump is selectively fluidly connectable to the low-pressure tank via the flow compensating valve. The flow compensating valve is controllable by or based on one or more of: a hydraulic pressure provided by the first hydraulic pump, a hydraulic pressure provided by the second hydraulic pump, and a hydraulic pressure at a fluid port of the at least one hydraulic actuator.
