Trunnion Metal Seated Ball Valves
The Next Generation in Trunnion Technology.
ValvTechnologies trunnion metal seated ball valves are designed for high-pressure and high-temperature applications.
The TrunTech® valve is designed to address the severe service demands of the upstream and midstream oil and gas industries. Its protected seat seals design provides long life and tight shut-off in abrasive / erosive conditions and meeting stringent fugitive emission requirements.
The NexTech® valve is designed as a high-end, severe service solution for the process and specialty markets. NexTech® also serves specialty applications to meet specific customer requirements. Utilizing the same coating and live-loading technology that built the V Series product line, but in a lower-torque, truly bi-directional package, NexTech® is a super solution for tough, high-cycling applications.
FAQs – Trunnion Ball Valves
What is a trunnion ball valve, and how does it differ from a floating ball valve?
Trunnion ball valves feature a ball supported at both top and bottom (via a trunnion), offering better sealing and lower operating torque in high-pressure systems. In contrast, floating ball valves rely on seat pressure and can result in higher torque and wear.
Why should I choose a trunnion ball valve for high-pressure or severe-service applications?
The trunnion design reduces seat load, lowers actuation torque, and provides reliable sealing in both high and low-pressure environments.
What applications are trunnion mounted ball valves best suited for?
Ideal for upstream/midstream oil & gas (including HIPPS), or erosive service, high cycle operations, high-integrity pressure protection abrasive systems, and where zero emissions and fire safety are critical.
