A hydraulic-power steering system is provided. A power-steering valve controls and varies a level of steering assist. A magnetic actuator varies torsional stiffness of the valve to change torque and produce a sufficient amount of the torque to generate full assist. A first valve is operatively connected to a steering pump and allows the full assist at a relatively low steering torque and through which flow from the steering pump is directed. A second valve is operatively connected to the steering pump. Current is applied to a solenoid valve that allows an increasing amount of the flow to be directed through the second valve in response to an input signal of increasing vehicle speed above a threshold value and closes in response to a signal identifying any of a plurality of advanced steering functions.
