摘要 |
A fluid-driven adapter for a mineral extraction system is provided. The adapter includes a sleeve (e.g., annular piston) that engages a mandrel disposed in a wellhead component and moves in an axial direction in response to fluid pressure. The adapter moves the mandrel between a first position and a second position to open or close passages in the wellhead component. The adapter includes a lock ring that moves in response to fluid pressure and that locks the adapter to a wellhead assembly to prevent axial movement of the adapter. Methods of operation are also provided. |
