What is the principle of selection for forged steel globe valves?
The principle of selection for forged steel globe valves is: The globe valves 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. On the pipeline where the flow resistance is not strict on the pipeline. That is, the place where the pressure loss is not considered. Small valves can be used with needle valves, instrument valves, sampling valves, pressure gauge valves, etc. 4, there are flow adjustment or pressure regulation, but the adjustment accuracy is not high, and the pipeline diameter is relatively small, such as the nominal diameter of ≤ 50mm pipeline, should be used. For small chemical fertilizers and large chemical fertilizers in synthetic industrial production, high-pressure angle shut-off valves or high-pressure angle throttle valves with nominal pressure PN160 nominal pressure 16MPa or PN320 nominal pressure 32MP...
