The AIL Trunnion Mounted Ball Valve is the preferred choice of ball valve in higher sizes and pressure ratings, and in critical process applications requiring special capabilities. In this design, sealing takes place by allowing the seat to move towards the ball along the flow axis, which leads to lower operating torques over other types of valves. The valves have advanced design features such as a built-in cavity relief mechanism, compact internal trunnion holder, and intrinsic double block and bleed facility. The valves are of two-piece design, bolted at the body connection joint and with flanged or butt weld ends, and are available in both reduced bore and full bore designs.
