What is a Trunnion Mounted Ball Valve?

The trunnion mounted ball valve is a quarterly turning valve that helps stop the flowing medium in the pipelines. The unique feature of the trunnion mounted ball valve is its disk in a round or spherical shape placed in the centre. This keeps rotating to stop or start the flow.
