It is precisely because of so many advantages that the pneumatic switch ball valve can be widely used in the industrial industry and play its role. The pneumatic switch ball valve uses compressed air as power to open or close. Pneumatic switch ball valve is also widely used in various industries, such as chemical industry, pharmaceutical industry, papermaking, etc. It is indispensable to the industrial automation process.

Due to the advantages of high control accuracy, convenient installation and debugging, electric control valves have been widely used in various industrial control systems. In the process of use, there is also a problem that puzzles the operators on site - the problem of valve internal leakage. In this regard, we will discuss the most common causes and solutions of internal leakage of electric control valves in the future, so as to help more people solve the problem of internal leakage.
