5 Conclusion High temperature and high pressure metal seat pneumatic ball valve is an energy saving and consumption reducing product that we focus on organizing and developing. After the product is applied locally, there is still much room for promotion. In addition to the advantages of R&D conditions, there is also an important advantage, that is, its convenient industrial test conditions can be repeatedly tested on the operating unit. At present, a large amount of data has been obtained, and a small number of samples have begun to conduct experiments. The experiment shows that the project can be used for the ultra supercritical steam turbine generator unit boiler, steam turbine body and pipeline drainage system, reaching the same level as imported products from western countries, and can replace imported products, with huge energy saving value.

When selecting pneumatic butterfly valves, we should select them according to these aspects, to understand what kind of pneumatic butterfly valves can help us most, and then understand how to use them to ensure the basic effect.
