The so-called pneumatic switch ball valve is the corresponding ball valve with the corresponding pneumatic actuator. In contrast, the execution speed of pneumatic actuators is relatively fast and very fast. Therefore, pneumatic actuators are usually also called pneumatic quick shut-off ball valves. Such valves can be installed anywhere in the pipeline and can be used. 　　

At the same time, due to their lack of key technologies in the maintenance work in the middle and later stages, the pneumatic butterfly valves with high cost performance lose their working efficiency. When it comes to the electric butterfly valve equipment, we also remind us to pay attention to the potential safety hazards. In order to make the pneumatic butterfly valve smoothly adjusted and used in the future, it is necessary to ensure the safety of the work site, and try to avoid using the pneumatic butterfly valve in the natural environment with large temperature difference. The natural environment with great temperature difference will make the sealing performance of pneumatic butterfly valve difficult, and can not reach the objective working condition.
