Copes-Vulcan’s Numbered Cascade Trim assembly is used in control valves where low flow rates and high turndown requirements prevail such as in desuperheater cooling water control, fuel oil control, blowdown and chemical feed.

A series of labyrinth grooves along the throttling surface of the plug provide a cascading effect so that the pressure drop is equally divided among the grooves, thereby reducing the seat wear that would normally be experienced if the entire pressure drop is taken across the seat. The cage guided tapered plug, in conjunction with the tapered cage bore, provides for maximum trim rangeability.
