Large Size Trunnion Ball Valve
Large size trunnion ball valve is consist of valve body, ball, seat, stem, transmission device and other key components.Owing to its unique design, the ball is fixed by the upper and lower two supporting axes, so that the ball will not tilt due to the thrust of the medium during the rotation process, thus ensuring the stability and sealing of the valve.
