The S-Series 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 Ultra strong curved flapper design provides full metal-to-metal sealing integrity. These ultra-slimline curved flappers allow operators to reduce their overall costs and maximize their return on investment by maintaining a large bore ID while reducing the casing sizes needed for the completion.
Features and Benefit
• Positive debris barrier at both ends of flow tube in full-open position
• Metal-to-metal static seal at upper and lower piston positions flapper equalizing system
• Non-elastomer dynamic piston seals
• It is highly reliable to use metal to metal sealing style in the sealing chamber
• Two step metal-to-metal sealing system provides strength and sealing under the harshest conditions
• Complete metal-to-metal well containment in the closed position (body/seat connections and flapper)
• Ultra strong power spring ensures smooth and reliable closures
• The optimized safety-valve design facilitates use of control-line communication and lockout tools to install a wireline-insert safety valve in the event of a malfunction, thus minimizing production disruptions
Application
• HTHP Well, Gas Well, Min Casing Size Well
• Deep Set Application; Hostile Environments
