Pneumatic ball valve is a kind of valve with higher processing and assembly requirements, and the processing precision of fixed pneumatic ball valve is required to be higher. Only by constantly summarizing the experience of the production process and exploring more scientific and innovative methods can we produce high-quality, high-level fixed pneumatic ball valves.

State controlled key polluting enterprises or forced to disclose information
Today, the Ministry of Environmental Protection publicly solicited opinions on the Measures for Self monitoring and Public Information Creation of National Key Monitoring Enterprises (Trial) prepared by the Ministry of Environmental Protection, and admitted that the disclosure of enterprise pollutant information is fundamentally invalid. With regard to enterprises that refuse to carry out their own monitoring and release their own monitoring information, the Ministry of Environmental Protection said that while disclosing information on their behalf, it will stop punishing them.
This year's global oil demand forecast is the first time that the International Energy Agency has raised this year's global oil demand forecast since January. The intergovernmental organization headquartered in Paris increased the estimated global oil demand this year by 65000 barrels per day.
The International Energy Agency predicts that the global daily demand for oil will increase by 800000 barrels or 0.9% this year, reaching 90.6 million barrels. Energy conservation and environmental protection will drive the demand for coal to gas. The basic reason for the high proportion of coal in energy in China is that the externalities of China's original coal with high pollution and high carbon emissions have not been reasonably priced, leading to its low cost of comprehensive utilization. However, in the future, our energy conservation and environmental protection regulations will gradually be in line with those in Europe and the United States. We estimate that this will increase the cost of coal utilization by 580/ton, and its energy share will decline significantly. Natural gas will become the most ideal alternative to coal. In fact, energy conservation and environmental protection are the basic driving force for natural gas development!
The application transformation of pneumatic butterfly valve should also be applied after the change of information period from time to time!
