Don-Nan Insert Guided Cage

One-piece, superior-strength guided cage for maximized fluid flow

Extend valve life

The 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 insert guided cage is available for use with barrels, plungers, and double-valve configurations. Metallurgy options include MONEL, alloy steel, and stainless steel, all with a Stellite insert.
