Patent ID: 7150326

Claim:
A method of using a fluid control system for a hydrocarbon well, the control system comprising a first portion having at least one actuator, an inner sleeve slidably disposed with the first portion and forming a longitudinal passageway, and at least two radial protrusions disposed at least partially in the inner sleeve and exposed to the passageway, the at least two radial protrusions being adapted to selectively extend into and retract from the passageway, the method comprising: using the control system with the at least two radial protrusions extended into the passageway and with a movable restriction disposed in the passageway and restricted in longitudinal travel between the at least two extended radial protrusions; and moving the inner sleeve relative to the first portion so that at least one of the at least two radial protrusions retracts from the passageway to selectively release the movable restriction from between the at least two radial protrusions.
