The reduced bore ball valve is mainly used for conveying gas or medium physical performance similar to water in the pipeline system, its weight about 30% lighter than the full port ball valve, and the flow resistance is only 1/7 of the same diameter of the globe valve. This type of ball valve is suitable for some low requirements, low convection resistance requirements and other conditions.
