Abstract

A choke valve for regulating a flow rate, a pressure or other parameters of a fluid flow may comprise a choke cage comprising a passage therethrough and a choke plug slidable within the passage. At least one conduit may pass through a wall of the choke cage and into the passage such that as the choke plug slides it may at least partially cover the conduit. A ring comprising a sintered superhard material may be secured within the conduit enhancing durability and wear resistance of the choke cage. A method for manufacturing such a choke cage may comprise subjecting grains of superhard material to high-pressure, high-temperature conditions sufficient to sinter at least some of the grains together, hollowing out the sintered superhard material to form a ring, and securing the ring within a conduit.
