The valves in this series are equipped with an inner valve that can be fully opened or closed by simply turning the stem a quarter turn.
When fully opened, a ball valve's offtake has the same bore as the pipeline, and its fluid resistance is negligible. Because of this, this automatic valve is best suited for on-off applications controlling liquids, gases and slurries.
