A flow control apparatus and associated methods of using provide enhanced longevity and reliability without requiring complex mechanisms. In a described embodiment, a choke for use within a subterranean well has multiple trim sets which may be individually selected by manipulation of a sleeve relative to an inner tubular cage. In another described embodiment, a single trim set is provided. Additional features include provision of a separate valve to selectively permit or prevent fluid flow through the single or multiple trim sets.
