  Pneumatic valve is an automatic actuator powered by compressed air, which has the characteristics of simple structure, reliable operation, and stable performance. As an indispensable and important component of industrial automation control system, the normal operation of pneumatic valve is crucial for the stable operation of production line. However, due to prolonged use or improper operation, pneumatic valves may experience various malfunctions during operation.



Fault:


Valve leakage.

Reason:


Impurities entering the valve can cause damage to the valve core, valve core, and valve seat during the opening and closing process, resulting in poor sealing. Or there may be an application error, such as using PTFE sealing for steam pipelines.

Solution measures:


Replace the valve core or valve core and valve seat, and apply them in suitable situations.
