Abstract
A throttling choke valve having a wear sleeve lining the interior surface of the cylindrical passage downstream of the valve sealing mechanism. A preferred embodiment of the wear sleeve has a removable retainer ring that fits between the wear sleeve and the fluid outlet. The retainer ring has a distal end that opens into the pipeline. At the distal end of the retainer ring the thickness of the wall of the retainer is decreased such that the interior surface is curved outward toward the interior surface of the pipeline.
