Fully Welded Trunnion Ball Valve

Fully Welded Trunnion Ball Valve

Platinum Valve’s fully welded side-entry ball valves are engineered for optimal performance, safety, and durability in critical pipeline applications. Offered in two- or three-piece configurations, these valves feature a fully welded body construction, eliminating external leak paths while reducing overall weight—making them ideal for both underground and above-ground installations.

With a solid double trunnion design and dual independent seats, the valves ensure bidirectional sealing, delivering tight shutoff and high reliability in high-pressure and high-temperature conditions. Designed to handle sweet or sour gas, acid service, and harsh pipeline environments, they can be customized to meet specific customer project requirements and comply with API 6D standards.
