JC
Trunnion mounted ball valves are based on a system that provide a fixed balland floating seat rings. The side load given by the pressure acting on the ball isabsorbed by the bearings. At low pressure the sealing on the seats is obtainedby the spring action on the seat rings. The more the pressure increases, themore it pushes the seats against the ball.
