Globe valves are often used to cut off or regulate and throttle flow. The following is the selection principle of globe valve:
1. High temperature and high pressure medium pipeline or device should be used on the globe valve. Such as thermal power plants, nuclear power plants, petrochemical systems of high temperature, high pressure pipeline.
2. The pipe road is not strict to the resistance of the pipe road. That is to consider the pressure loss place.
3. Small valve can choose needle valve, instrument valve, sampling valve, manometer valve, etc.
4. There is flow regulation or pressure regulation, but the adjustment accuracy is not high, and the pipe diameter is relatively small, such as pipe diameter less than or equal to 50mm on the road, it should be selected.
5. For water supply and heat supply projects of urban construction, globe valve, balance valve or plunger valve can be used for pipes with small nominal size, such as pipelines with diameter less than 150mm.
