A zonal hydraulic system comprising: a power source; a main port; a main return port; a backup port; a backup return port; a consumer port; a consumer return port; a first circuit for a main system that extends from the main port to the consumer port through a consumer and back from the consumer return port to the main return port; a main pump connected to the main port and the main return port, the main pump is configured to pump main fluid through the main port and to receive the main fluid returned through the main return port; a second circuit for a backup system that extends from the backup port to the consumer port through the consumer and back from the consumer return port to the backup return port; a backup pump connected to the backup port and the backup return port, the backup pump is configured to pump backup fluid through the backup port and to receive the backup fluid returned through the backup return port; a first pilot operated shutoff valve located on the first circuit between the main port and the consumer port that in a first position provides fluid communication between the main port and the consumer port and in a second position prevents fluid communication between the main port and the consumer port; a first pilot port connected to the first pilot operated shutoff valve; a second pilot operated shutoff valve located on the first circuit between the consumer return port and the main return port that in a first position provides fluid communication between the consumer return port and the main return port and in a second position prevents fluid communication between the consumer return port and the main return port; a second pilot port connected to the second pilot operated shutoff valve; and a pilot flow path that extends from the main port to the first and the second pilot ports (140, 142) of the first and second pilot operated shut off valves (134, 136); a first solenoid valve connected to an electrical power source and located on the pilot flow path between the main port and the first and the second pilot ports (140, 142) of the first and the second pilot operated shutoff valves (134, 136) that in a first position provides fluid communication between the main port and the first and the second pilot ports (140, 142) and in a second position prevents fluid communication between the main port and the first and the second pilot ports (140, 142), wherein the first circuit in an isolation mode of operation is isolated from the consumer without requiring utilization of a backup fluid contained in the second circuit,wherein the first pilot operated shutoff valve is in the second position and the second pilot operated shutoff valve is in the second position in the isolation mode of operation. a power source;
