Abstract:
Disclosed are a method and device for modulating the downstream pressure output of a pressure reducing hydraulic control valve in response to the flow demand fluctuation the method comprising. Included is an adjustable pressure pilot valve mechanism having a drive element extending from the control valve. The drive element is displaceable in response to a flow capacity through the hydraulic control valve. Also included is an adjustable pressure pilot valve deployed along a control tube connecting an upstream pressure port to a downstream pressure port, the adjustable pressure pilot valve associated with the drive element such that adjustable settings of the adjustable pressure pilot valve are responsive to displacement of the drive element.
