Pressure control valves react or respond through a pressure control regulator. The pressure control regulator directs water flow which positions the sleeve during operation. If the control function is pressure reducing, the sleeve position (or flow through the valve) is controlled by downstream pressure. If the control function is pressure sustaining or relief, the sleeve position is controlled by upstream pressure.
