Ball Valves

Global Valve and 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 and 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 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.
