Priority flow dividers are used in systems in which one branch of the system contains essential functions that must be performed, while the other branch contains less vital functions. It is disclosed for dividing hydraulic fluid flow between a steering circuit and an auxiliary circuit thereby providing better efficiency and greater productivity for the auxiliary circuit. The priority flow divider includes a cylindrical housing having a slidable spool valve therein, and the housing further includes an inlet port connected to the steering pump in the steering circuit, a discharge port connected to the steering valve, in the steering circuit, and a discharge port connected to the auxiliary hydraulic circuit.
