Because the stem opening or closing stroke of the globe valve is relatively short, and has very reliable cutting function, and because the change of the valve seat opening is in direct proportion to the stroke of the disc, it is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting or regulating and throttling use.
