FRN flapper-type wireline-retrievable safety valves

The FRN wireline-retrievable flapper valve, which is normally closed, is held open by hydraulic control pressure from the surface. The valve operates on a hydraulic-piston principle. To open, tubing pressure slightly higher than the well pressure below the closed flapper is applied. Once well pressure is equalized across the closed flapper, hydraulic pressure is applied to the piston, which pushes the flapper open.

Applications

New completions
Deep set
High pressure

Features

High-strength rod-piston actuation
Non-equalizing 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 flow path of well production when the valve is in open position
Designed for easy field servicing

Benefits

Minimal hinge-pin stress during opening and closing cycles
Working pressures up to 12,500 psi
Allowable setting depths up to 9,000 ft
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
Ease of on-location servicing of the external packing helps reduce downtime and operating costs
