"IMPROVED BALL AND CAGE VALVE FOR DOWNHOLE RECIPROCATING PUMPS" ABSTRACT OF THE DISCLOSURE In the conventional ball and cage valve used in downhole reciprocating pumps, the cage of the valve is formed with ports having a helical configuration. As a result, produced fluid flowing through the ports is caused to form vortices, thereby better maintaining contained sand in suspension.
