FXE Flapper-Type Valves

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.


  • General production completions 


  • Equalizing-type flapper closure
  • Solid construction flapper made from bar stock
  • Spherical radius seat on flapper improves seal reliability
  • Sealing and seating surfaces are out of the well production flow path when valve is in the open position


  • Minimal hinge pin stress during opening and closing cycles
  • Allowable working pressures up to 15,000 psi (1035 bar)
  • Allowable setting depths up to 3,000 ft (914 m)
  • Pump-through capability built into the valve design
  • Compatible with Otis® X®, R®, RQ, RPV, and SAFETYSET® lock mandrels and with Halliburton tubing-retrievable safety valves in-depth ratings and material selections
