Abstract

Pressure regulating valve assembly (5) comprising: a valve (50) having an upstream side (51) receiving an input flow (I) and a downstream side (52) providing an output flow (O), actuating means (60) for opening and closing the valve (50), including partially opening the valve (50), and regulating means (70) controlling the actuating means (60) to open or close the valve (50) or to partially open the valve (50). The regulating means (70) comprise a sense pressure port (71), wherein the pressure present at the sense pressure port (71) is maintained constant by the regulating means. A chamber (80) is provided that has a first entry orifice (81), a second entry orifice (82) and an exit orifice (83), wherein the first entry orifice (81) is connected to the valve upstream side (51), the second entry orifice (82) is connected to the valve downstream side (82), and the exit orifice (83) is connected to the sense pressure port (71), wherein the exit orifice (83) is provided such that the pressure present at the exit orifice (83) lies between the pressure at the first entry orifice (81) and the pressure at the second entry orifice (82).
