FXE wireline-retrievable flapper valve, which is normally closed, is held open by hydraulic control pressure from the surface.Talk to an expert
The valve operates on a hydraulic piston principle. To open, hydraulic pressure slightly higher than the well pressure is applied to move the piston downward. This pressure unseats the secondary seat, allowing pressure to enter through equalizing ports. Then, as additional hydraulic pressure is applied to the piston, it continues downward movement, pushing the flapper open.

Durability and reliability of through metal-to-metal sealing of the contoured flapper, enhanced body connections, and debris isolation.
Halliburton tubing-retrievable and wireline-retrievable subsurface safety valves are a field-proven solution for operators.
