A steering system for a work vehicle includes a steering hand pump, a hydraulic main supply line fluidly coupled with the steering hand pump and including a check valve, and a normally open, two position valve. The valve includes an inlet fluidly couplable with a pressurized access point of a hydraulic sub-system, an outlet fluidly coupled with the main supply line on a downstream side of the check valve, and a pilot port fluidly coupled with the main supply line on an upstream side of the check valve. The valve is operable in the closed position based on pressure in the main supply line when the main supply line is pressurized from a pressure source, and operable in the open position and interconnecting the pressurized access point with the main supply line through the outlet when the main supply line is not pressurized from the pressure source.
