Abstract
A valve for use in a wellbore includes a replaceable choke device that is threaded into at least one opening formed through a sidewall of a tubular housing of the valve. The choke device is sealable on the sidewall of the tubular housing with an elastomeric sealing component, and the choke device controls at least one of fluid pressure within the tubular string and a pressure drop across the valve. The valve also includes a flow sleeve carried by the tubular housing for movement relative thereto between a first position in which fluid flow s permitted across the valve, a second position in which the flow sleeve prevents fluid flow across the valve, and a third position in which the flow sleeve is locked in place relative to the tubular housing by a lock ring.
