TRMAXX surface-controlled subsurface safety valves (SCSSVs) are premium, tubing-retrievable valves with a conventional spring-type design. They incorporate a single rod piston with reliable, spring-energized, filled Teflon sealing elements; a static, full-closed, metal-to-metal seal; and a static, fully open seal and centralizing system.
A modular design enables flexibility in material and engineering options, including a wide range of nipple profiles.
For maximum reliability, all TRMAXX valves have only two body joints and use proprietary threads to achieve a reliable, metal-to-metal seal. The premium flapper mechanism also features full metal-to-metal sealing, together with a secondary soft seat, and it meets a leakage acceptance criterion that is substantially more stringent than API and ISO specifications.
The optional flapper-mounted equalizing system is an industry-recognized method for equalizing pressure across the flapper.
