A fluid power system for actuating three separately controllable double acting fluid motors each selectively providing a separate function in which the number of hydraulic lines to the motors is minimized. A first function valve supplies power to the first motor and a second function valve provides power to a selector valve which selectively connects the power to the second and third motors. The selector valve is pilot actuated from one of the lines to the first motor and a control valve supplies power to the one line for actuating the selector valve. The system is particularly useful for a lift truck for minimizing the number of hydraulic lines connected to the motors on the carriage of the truck.
