Selection principle:
1. The manufacturer of the Dual plate wafer Non-return check valve tells you that a stop valve should be used in the pipeline or device for high temperature and high pressure media. Such as thermal power plants, nuclear power plants, high-temperature and high-pressure pipelines of petrochemical systems.
2. The stop valve is used in the pipeline that does not require strict flow resistance on the pipeline. That is, where the pressure loss is not considered.
3. Small valves can choose needle valves, instrument valves, sampling valves, pressure needle valves, etc.
4. The manufacturer of the Dual plate wafer Non-return check valve tells you that there is flow adjustment or pressure adjustment, but the adjustment accuracy is not high, and the pipe diameter is relatively small. For example, a stop valve should be used on a pipe with a nominal passage of ≤50mm .
5. The manufacturer of Dual plate wafer Non-return check valve tells you that small fertilizers 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 and a nominal pressure of 16MPa or PN320 and a nominal pressure of 32MPa.
6. In the desiliconization workshop of the alumina Bayer process and the pipelines that are prone to coking, it is easy to choose a direct-flow stop valve or direct-flow throttle valve with a separate valve body, a removable valve seat, and a cemented carbide seal pair.
7. The manufacturer of Dual plate wafer Non-return check valve tells you that in the water supply and heating projects in urban construction, the nominal passage of smaller pipelines, you can choose a stop valve, balance valve or plunger valve, if the nominal passage is less than 150mm pipeline.
