Remotely actuated adjustable choke valve and method for using same

A remotely-adjustable valve employable in an enhanced-lift recovery system and a method of adjusting the same. The valve comprises: (1) an elongated valve body having a process fluid inlet and a process fluid outlet, (2) an elongated valve stem disposed within the valve body for axial displacement relative thereto to adjust a rate of process fluid flow between the fluid inlet and the fluid outlet as a function of a relative axial position of the valve stem with respect to the valve body and (3) a cam disposed within the valve body and coupling the valve body and the valve stem, the cam providing a plurality of axial displacement positions thereon to place the valve stem at a selected one of a plurality of relative axial positions with respect to the valve body, the valve body having a control fluid pressure port for allowing a control fluid pressure to be introduced into and released from the valve to reciprocate the valve stem axially with respect to the valve body between cocked and set positions, the cam moving from a first axial displacement position to a second axial displacement position as the valve stem is reciprocated, a difference between the first and second axial displacement positions thereby causing an adjustment of the rate of process fluid flow between the fluid inlet and the fluid outlet.
