Principles for selecting forged steel globe valves
Release Date:2023.05.17
1. Stop valves should be selected for pipelines or devices with high-temperature and high-pressure media. High temperature and high-pressure pipelines in thermal power plants, nuclear power plants, and petrochemical systems.
2. On pipelines with less strict requirements for flow resistance. Places where pressure loss is not considered much.
3. Small valves can choose from needle valves, instrument valves, sampling valves, pressure gauge valves, etc.
4. There is flow regulation or pressure regulation, but the requirement for regulation accuracy is not high, and the pipeline diameter is relatively small. For example, on pipelines with a nominal diameter of ≤ 50mm, it is recommended to choose.
5. Small and large fertilizers in synthetic industrial production should use high-pressure angle globe valves or high-pressure angle throttle valves with a nominal pressure of PN160, a nominal pressure of 16MPa, or PN320, a nominal pressure of 32MPa.
6. In the desilication workshop and coking prone pipelines of alumina Bayer process production, it is easy to choose DC stop valves or throttle valves with separate valve bodies, removable valve seats, and hard alloy sealing pairs.
7. In the water supply and heating engineering of urban construction, for pipelines with smaller nominal diameter, cut-off, balance valves, or plunger valves can be selected, such as on pipelines with a nominal diameter less than 150mm.
