A filter system with flow regulation includes a filter interposed along the fluid passageway and a differential valve in fluid series therewith. The valve may use the upstream reference hydraulic pressure at the filter inlet and a downstream hydraulic pressure thereof to generate a valve position that regulates fluid flow along the fluid passageway. This can partially restrict flow and reduce pressure differential across the filter system and effectively closes off flow through the system when pressure differential is high. This may be used in aircraft or other fueling applications to limit flow and cause the operator to change the fuel filter once fuel flow slows to a trickle when the differential valve effectively closes due to higher differential pressure. The valve is also capable of a fully closed position at high pressure differential state.
