The API 6D trunnion mounted ball valve 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 trunnion mounted ball valves are widely used in oil
and gas industry.
The family of API 6D trunnion mounted ball valve are classified into 3pcs forged body trunnion valve, 2pcs cast steel body trunnion ball valve, and one pc forged body top
entry trunnion ball valve. The one pc forged body top entry trunnion ball can avoid the leaking risk from the connection between
body and closure. The other advantage of top entry 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. The 3pcs forged steel trunnion type of ball valve is most widely used trunnion ball valve of oil and gas industry valves because it's reliability and economity.
