Selection principle of stop valve:

1. High temperature, high pressure medium on the pipeline or device should choose stop valve. Such as thermal power plant, nuclear power plant, petrochemical system of high temperature, high pressure pipeline.

2. On the pipeline where the resistance requirement is not strict. That is, the pressure loss is not considered.

3. Small valve can choose needle valve, instrument valve, sampling valve, pressure gauge valve, etc.

4. There are flow regulation or pressure regulation, but the regulation accuracy is not high, and the pipeline diameter is relatively small, such as the nominal diameter ≤ 50 mm pipeline, it should be selected.

5. High pressure angle stop valve or high pressure angle throttle valve with nominal pressure of pn160, nominal pressure of 16MPa or pn320, nominal pressure of 32Mpa should be selected for small and large chemical fertilizers in synthetic industry.

6. In the desiliconization workshop of alumina Bayer process and the pipeline easy to coking, it is easy to select the direct current stop valve or direct current throttle valve with separate valve body, removable valve seat and cemented carbide sealing pair.

7. In the water supply and heat supply engineering of urban construction, the cut-off valve, balance valve or plunger valve can be selected for the pipeline with smaller nominal diameter, such as the pipeline with nominal diameter less than 150 mm.
