Abstract:
A choke valve for use in reverse flow when mounted on a wellhead or manifold. The choke valve includes a valve body forming a T-shaped bore to provide a vertically extending bottom opening and a horizontally extending side opening. Flow trim is positioned in the T-shaped bore, optionally in a tubular sleeve or removable cartridge. The flow trim includes a tubular cage having a side wall forming an internal bore aligned with the body bottom opening, and a single flow port or a plurality of flow ports, each of the single flow port or plurality of flow ports being positioned for alignment with the body side opening. In reverse flow mode in the valve body, fluid from the bottom opening enters the cage and exits through the single flow port or plurality of flow ports directly into the body side opening.
