Insert Guided Cage
The Don-Nan Insert Guided Cage is similar to hard-lined cages, but uses a Stellite insert that has been inertia friction-welded in place. This single-piece cage extends valve life in applications that would otherwise fail at a much faster rate due to violent ball rattle caused by turbulent gas and fluid flow.
The Don-Nan Insert Guided Cage is available for use with barrels, plungers, and in double valve configurations. Metallurgy options include Monel®, alloy steel, and stainless steel, all with Stellite insert.
