Abstract
In a choke valve having a cage with external sleeve flow trim, the large ports of the cage are aligned with the axis of the inlet bore and a deflection bar is positioned at the top end of the main bore, opposite to the inlet bore. The flow patterns within the choke are consequently altered with significant reduction of localized erosional wear areas.
