The pneumatic O-type ball valve is essentially derived from the pneumatic diaphragm control valve, which removes the valve positioner and valve limit switch on the basis of the pneumatic control valve. The stroke of the pneumatic valve can be controlled according to the pressure of the control air source to meet customer needs. Pneumatic O-ring ball valve can adjust and cut off, and is commonly used for two position control. It has a simple flow path, completely forms a straight pipe channel when fully opened, and has small pressure loss. It is especially suitable for high viscosity, suspension, pulp and other fluid occasions. Reliable sealing, small leakage, soft sealing ball valve can achieve bubble level sealing.

In recent years, the development of machine tools, instruments and other categories has led to the rapid growth of China's pneumatic butterfly valve industry. China's pneumatic butterfly valve has fundamentally established its market economic position, and has also become a new investment category that is widely concerned by countries around the world. According to the observation of Tongfeng pneumatic butterfly valve, the world capital has accelerated its penetration into China's pneumatic butterfly valve industry. The international pneumatic butterfly valve industry giants have rushed into China's pneumatic butterfly valve market in a number of ways. While China's pneumatic butterfly valve enterprises have wonderful prospects, they will also face fierce competition.
Although there is still a big gap compared with the international coverage rate of more than 70%, it has made great progress. The coverage area of pneumatic butterfly valve specifications is mainly the Pearl River Delta. In particular, the coverage rate of pneumatic butterfly valve specifications used by Guangdong pneumatic butterfly valve enterprises is far higher than that of pneumatic butterfly valve enterprises in other regions. According to the analysis of Tongfeng pneumatic butterfly valve, during the "12th Five Year Plan" period, China's pneumatic butterfly valve industry has great market potential, and will also have a good opportunity to draw on foreign advanced technology and capital. Only domestic pneumatic butterfly valve enterprises can fully use the opportunity of China's rapid rise of pneumatic butterfly valve industry, through providing relevant services to achieve the purpose of integrating resources, supporting each other, and practicing internal skills, Accelerate the structural transformation of products and enterprises, and increase the research and development of high-end pneumatic butterfly valve data and technology. China will further stabilize its position as the "world's largest pneumatic butterfly valve country" and strengthen its competitiveness, so that the pneumatic butterfly valve industry can get out of the current unfavorable situation and change from the "big pneumatic butterfly valve country" to the "powerful pneumatic butterfly valve country". It is not an illusion that China will develop into the world pneumatic butterfly valve center in the next decade.
