The selection principle of the globe valve is:
1. The shut-off 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, high-pressure pipelines of petrochemical systems.
2. On the pipeline where the flow resistance is not strict. That is, the place where the pressure loss is not considered.
3. Small valves can be used with needle valves, instrument valves, sampling valves, pressure gauge valves, etc.
4. There is flow regulation or pressure regulation, but the adjustment accuracy is not high, and the pipeline diameter is relatively small. For example, the pipeline with nominal circulation of ≤50mm should be used.
5. For small chemical fertilizers and large chemical fertilizers in synthetic industrial production, high-pressure angle-type shut-off valves or high-pressure angle-type globe valves with nominal pressure PN160 nominal pressure 16 MPa or PN320 nominal pressure 32 MPa should be used.
6. In the desiliconization workshop and the easy-coking pipeline in the production of alumina Bayer method, it is easy to select the DC-type shut-off valve or the DC-type stop valve with the valve body separated, the valve seat can be removed, and the carbide seal pair.
7. In the water supply and heating projects in urban construction, it is known to pass through smaller pipelines, and it is possible to use a shut-off valve, a balancing valve or a plunger valve, such as a pipe that is nominally passed through less than 150 mm.
