Fault 3: The actuator oscillates frequently due to improper parameter setting of the regulating system. Solution: Improper parameter setting of the regulator will cause the system to oscillate to varying degrees. For a single loop regulation system, if the proportional band is too small, the integration time is too short, and the differential time and differential gain are too large, the system may oscillate. These parameters can be reasonably selected through system tuning to keep the loop at a stable speed. 　　

The sealing performance of pneumatic butterfly valve is a key point when it is used. If you want to achieve its own sealing performance at this time, you have adopted the spherical shape in technology, so that different places have a better fit, and the mutual sealing performance can be improved naturally. The breakthrough in modeling is achieved through continuous improvement of technology and other aspects. Only when we really achieve this, can the sealing be truly guaranteed.
