We are a leading manufacturer of oil and gas industry valves, we have more than 15years experience in producing top entry trunnion mounted ball valve.
The API 6D Stem Extension Top Entry Trunnion Mounted Ball Valve is one kind of oil and gas industry valves. It has two floating seats with springs loaded, in which the ball is fixed at two pivot points, and the process pressure pushes the upstream seat against the ball's sealing surface. This design applies continuous pressure against a trunnion mounted ball after the ball is installed. The API 6D Stem Extension Top Entry Trunnion Mounted Ball Valve is widely used in oil and gas industry.
In trunnion type of ball valve family, one pc forged body top entry trunnion ball valve avoids the leaking risk from the connection between body and closure. The other advantage of top entry trunnion ball valve design is it makes the emergency on-line maintenance to be easier and quicker, because the valve ball needn’t to be removed from pipe line. One the other hand, the Stem Extension Top Entry Trunnion Type Ball Valve is very costly, because it requests to machine out its valve body from one pc integral forged steel.
