Description of the specific characteristics of the cut-off solenoid valve

The shut-off valve solenoid valve is one of the most widely used valve types. With the development of ball valves and butterfly valves, the application of the globe valve is replaced by a part, but from the characteristics of the globe valve itself, the selection principle 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. Some pipelines that have little consideration for flow resistance loss.
3, there are flow regulation 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.
4. Small valves can be used with needle valves, instrument valves, sampling valves, pressure gauge valves, etc.
5. For high-yield fertilizers and large fertilizers in synthetic industrial production, high-pressure angle shut-off valves or high-pressure angle throttle valves 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 throttle 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 the cut-off, balance valve or plunger valve can be used.
