This versatile tool is suitable for a wide range of applications including liner-top isolation (gravel-pack, screen, frac-pack, slotted liner, etc.), fluid loss control (FLCV), completion suspension barriers (batch completion, fluid-loss), deepwater contingency barriers, single-trip completion barriers, shallow-set lubricator valves, and tubing hanger isolation devices. It offers key benefits such as eliminating intervention during completion deployment, mechanical contingency operation, market-leading thru-bore, superior pressure and temperature ratings, no debris upon opening, and adaptability across numerous applications. Key features include the ability to be run in hole (RIH) fully open and remotely or mechanically closed, multiple opening options (hydraulic, mechanical, or controlled leak), multi-cycle opening, V0 ISO qualification, a patented equalizing feature to aid in opening, and flexibility to be run above or below the production packer.
