The bolted bonnet globe valve is a globe valve whose body cover is bolted, and a gasket or an octagonal sealing ring is installed in the middle as a seal. According to the different installation positions, the globe valve can be divided into a straight-through globe valve (T-type globe valve) and a straight-through globe valve (Y-type globe valve). Because the opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow regulation.
