S Tubing Retrievable Safety Valve
S Tubing Retrievable Safety Valve
The S type tubing retrievable safety valve is a single rod-piston non-elastomer flapper valve designed for where ultimate reliability is required. The piston achieves a metal-to-metal seal at its uppermost and lowermost positions to seal well pressure from the control system. The spherical radius flapper design provides full metal-to-metal sealing integrity.
Features and Benefit
Non-elastomer dynamic piston seals
Metal-to-metal static seal at upper and lower piston positions Clean-out ports in flow tube’s upper end
Flow tube shock absorber
Positive debris barrier at both ends of flow tube in full-open position Metal-to-metal face seat at flow tube downstop
Applications
Gas Well HTHP Well
Deep Set Application Hostile Environments
