An aspect of the present disclosure relates to a steering system having first and second steering circuits in fluid communication with a fluid actuator wherein the steering circuits are disposed in parallel to each other. The second steering circuit includes a proportional valve having a load-sense feature in selective fluid communication with a load-sense connection and the first steering circuit. The load-sense feature is open to the first steering circuit when the proportional valve is in a neutral position and closed to the first steering circuit when the proportional valve is moved to a first or second steering position. When the proportional valve is actuated from the neutral position to the first or second steering position the movement of the proportional valve closes the load sense feature from the first steering circuit and operates to deactivate the first steering circuit.
