The globe valve refers to the valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the opening or closing stroke of the valve stem of this kind of valve 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 adjustment. Therefore, this type of valve is very suitable for use as a cut-off or adjustment and throttling.
The selection principle of the globe valve is:
1. The globe valve should be used on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high-temperature and high-pressure pipelines in petrochemical systems.
2. On the pipeline where the convection resistance is not strict, that is, the place where the pressure loss is not considered.
3. There are flow adjustment or pressure adjustment, but the adjustment accuracy is not high, and the pipe diameter is relatively small, such as the pipe with a nominal passage of ≤50mm, it should be selected.
4. For water supply and heating projects in urban construction, smaller pipelines are nominally passed through, and globe, balance valves or plunger valves can be selected, such as pipelines with a nominal diameter of less than 150mm.
