Malfunction | Pneumatic solenoid valve failure reasons |
Blocking | The waterproof tape wound into the piston rod, so that the reversing air produced impurities, causing blockage |
Seal is damaged | Entering high temperature or corrosive fluid, wear or corrosion of the sealing ring |
air leakage | Seal ring damage leads to air leakage, reversing pressure is insufficient, reversing is not in place |
The reversing difficult | Insufficient starting pressure, Vibrations, surrounding magnetic field, dense pallet, dense pallet valve |
Commutation failure | Control signal error |
unable to commutation | Coil burned,internal plugging of valve body |
Coil burned | Voltage mismatch, overload |
