First, check whether the valve is normal or not. The valve is the most important core component of the whole pneumatic switch ball valve. Therefore, no matter when the pneumatic switch ball valve is installed or used, it is necessary to check whether the valve of the pneumatic switch ball valve is normal or not. You can try to repeatedly open and close the valve without installing it, Confirm that the valve can work normally, and then carefully check every detail of the valve. After confirming that the valve is intact, install it again, and the effect will be better. 　　

The fifth is the leakage of the pneumatic butterfly valve hydraulic system, which makes operators feel headache. This situation is mainly manifested in the seepage oil leakage of swing cylinder and each regulating valve. Once serious leakage occurs, the system will be unable to maintain or even cause pump tripping. The solution to this kind of fault depends on the fishbone diagram. Due to the limited space, the details will not be discussed here. In the future, we will have the opportunity to write a related article for your reference.
