TRMAXX Premium Tubing-Retrievable, Surface-Controlled Safety Valve

Overview Library

Self-equalizing, premium rod piston flapper valve for working pressures up to 10,000 psi

The TRMAXX premium tubing-retrievable, surface-controlled safety valve is a conventional spring type design, incorporating 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. 

Reliable metal-to-metal seals

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.

Wide range of operating environments

The modular design allows a wide range of material and design options that provide cost-effective solutions for conventional, deepset, injection, and cement-through applications.
