A hydraulic system is disclosed. The hydraulic system may have a pump configured to draw low-pressure fluid from one of a first passage and a second passage and discharge fluid into the other of the first and second passages, and an actuator coupled to the pump via the first and second passages. The hydraulic system may also have at least a first control valve fluidly connected between the first and second passages to selectively direct fluid from one of the first and second passages to bypass the pump and flow into the other of the first and second passages. The hydraulic system may further have at least a second control valve fluidly connected in parallel with the at least a first control valve to selectively direct fluid from one of the first and second passages to bypass the actuator and flow into the other of the first and second passages. |
