Ball Valve and Controls trunnion design

Ball valves and Controls trunnion design ball valves incorporate the use of upper and lower supports  to retain the ball under pressure. ball Valve and Controls API 6D Trunnion ball valve 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 and 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 Ball valves 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 Ball Valve and 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.
Ball Valve and 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.
