Step 1: Check whether the solenoid valve is normal, whether the coil is worn out or in poor contact, and whether the spool of the solenoid valve is stuck. Repair method: Replace the coil. Clean up the stuck things on the solenoid valve. Replace the solenoid valve if the above method is useless. Step 2: Check whether the pneumatic actuator works normally, such as cylinder piston blow-by, cylinder body and end cover or shaft leakage, etc. Repair method: Disassemble the actuator and check whether the seal is damaged. Whether the surface of the cylinder inner hole is damaged. Replace the damaged seal ring, replace the piston, or the cylinder. Step three check whether there is something inside the valve core or valve plate stuck. Maintenance method: cleaning miscellaneous
