The maintenance of the core components of the pneumatic butterfly valve is very important. Although the surface of the valve looks small and inconspicuous, it is the center of the whole machine, which determines whether the machine can operate normally. Therefore, the operator must always be responsible for the maintenance and adjustment of the valve. Before the machine runs, check each valve inside the machine, If the valve is found to have problems, it is necessary to adjust the valve in time or replace the valve directly.
