2.Trunnion mounted ball valves

The ball is fixed and the seat rings are floating,free to move along the valve axis,side load generated by pressure acting on the ball is absorbed by bearing,at low pressure the seat sealing acting is achieved by the thrust of the springs acting on the seat.As the pressure increases the fluid pressure pushes the seat rings against the ball,making the sealing more reliable.
