ABSTRACT:
Methods and apparatus for use within a production pipeline or other flowbore to reduce fluid pressure and regulate fluid flow while minimizing erosion effects caused by particulate matter in the fluid, wherein varying geometries with respect to multiple components within a choke valve are utilized to effectuate multiple changes in fluid flow direction, causing a fluid pressure drop at each directional change.
