Abstract

An apparatus and method are provided for modifying a flow characteristic, such as a valve characteristic, through use of a flow characterizing device having a segmented flow characterizing channel therein including three or more discrete segments, at least one of which is a through-hole, for modifying a flow of fluid through a flowpath, in which the flow characterizing device is mounted, when a controlling edge, mounted in the flowpath adjacent the flow characterizing device, is aligned with one or more of the three or more discrete segments of the flow characterizing channel. Either or both of the flow characterizing channel and the controlling edge are selectively movable relative to one another.
