Improve reliability with 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.
