API 6D Trunnion Mounted Ball Valves

API 6D Valves / Double Block and Bleed Valves

Global Valve & Controls trunnion design ball valves incorporate the use of upper and lower supports (GVC trunnion plate system) to retain the ball under pressure. Global Valve & Controls API 6D trunnion ball valves have a secondary sealant injection system for stem seals and seats in the event of providing a temporary seal to an otherwise damaged area. The Global Valve & Controls trunnion ball valve design using the upper and lower trunnion plate system essentially doubles the safety and reliability of a standard trunnion ball valve.

The Global Valve & Controls trunnion plate system feature is standard on all Global Valve & Controls API 6D trunnion ball valves from 4” and up (ANSI 600 through 2500). It permits the valve to be installed in either direction, since the trunnion prevents the ball from shifting — or worse, blowing out – under high pressure applications.

Another important benefit of the Global Valve & Controls trunnion plate system design is that it allows the ball to only rotate a quarter turn with no hysteresis thus more control and reliability under extreme applications.

Global Valve & Controls standard API 6D trunnion ball valves use materials in accordance with NACE MR0175/ISO15156. In order to ensure compliance customers must provide application specific operating conditions.
