ABSTRACT:
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 selected by manipulation of an inner tubular cage. Additional features include provision of releasable latches to maintain the cage in a desired position, and utilization of biasing members to bias the cage toward a neutral position in which all of the trim sets are closed.
