API 6D Fully Welded Body Ball Valve

RSF is a professional manufacturer of API 6D Fully Welded Body Ball Valve. We have automatic welding machine, WPS and PQR are available. We have full range products of oil and gas industry valves.

API 6D Fully Welded Body Ball Valve is widely used in long transmission pipe of oil and gas because the welded body construction prevents the trunnion ball valve from leaking risk through valve body.

The family of API 6D Trunnion Mounted Ball Valve is classified into 3pcs forged body trunnion valve, 2pcs or 3pcs 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 valves are most widely used trunnion ball valve of oil and gas industry valves because it's reliability and economy.

The trunnion mounted ball valve is one kind of widely used oil and gas industry valves. The API 6D Welded Body Trunnion Mounted Ball Valve has two floating seats assembling with springs loaded, in which the ball is fixed at two pivot points, and the process pressure pushes the upstream seat against the trunnion ball's sealing surface. This design applies continuous pressure against a trunnion mounted ball after the ball is installed.
