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：
The upper and lower cylinders are in series, and the valve cannot be opened or closed.
Reason：
The air source is dirty or contains water, and the usage environment is dirty. If a muffler is not installed at the air source port, impurities may enter the cylinder, or the cylinder may be exposed to high temperatures for a long time, resulting in damage or aging of the piston seal, leading to seal failure.
Solution measures：
Replace the piston sealing ring, and in severe cases, replace the entire cylinder. If necessary, adjust the valve installation position.
