Abstract
A surge relief valve suitable for high pressure application, for example in a crude oil pumped pipeline. The valve has a plug movable to expose different areas of an energy-absorbing cage trim to fluid flow. The plug position is controlled by a control device proportionately responsive to changes in upstream fluid pressure. The valve requires no external power for its actuation.
