The Trunnion Ball Valve is also called trunnion mounted ball valve. The ball of trunnion ball valve is fixed and it doesn't move with medium pressure. It has floating seats. The seats move with the medium pressure to press the ball against the sealing O-Ring to ensure sealing reliability. Bearing could be mounted on either top shaft or bottom shaft by which it will reduce the operation torque.  To ensure tight sealing at low pressures, special springs are applied to force the seats against the ball.
