<p>The invention relates to a valve assembly (1), in particular reducing valve assembly, comprising a first energy dissipating means (13) and a second energy dissipating means (15) and a valve closing means (17) for opening and closing the valve wherein the geometry of the plurality of apertures (29) of the first energy dissipating means and the geometry of the plurality of the apertures (37) of the second energy dissipating means is such that independently of the opening state of the valve assembly, the pressure drops at the first and second energy dissipating means are better balanced to be able to reduce the effect of cavitation on the housing of the valve assembly.</p> |
