Abstract
A flow characterizing device (30) for a valve comprises: a body (31) in form of a disc with a centerline, the body (31) having an inner surface (33) corresponding to the outer surface of the valve member when the flow characterizing device (30) is installed in the flow path of the valve; and an outer surface (37), the inner and outer surfaces (33, 37) of the flow characterizing device (30) disposed in a spaced relationship along the centerline of the flow characterizing device (30). The body (31) of the flow characterizing device (30) further comprises a flow characterizing channel (49) therein extending between the inner surface (33) and the outer surface (37) of the flow characterizing device (30), thereby providing fluid communication between the inner and outer surfaces (33, 37) of the flow characterizing device (30), and defining an opening (32) in the inner surface (33) of the flow characterizing device (30).
