Pulse valve failure and trouble shooting
| Common Failure and trouble shooting | |||
| Use Period | Failure phenomena | Possible reason | Troubleshooting |
| All the valves cann't be open, but the pilot can work | Check if the gas dome pressure is too low | Check if leaking | |
| Some valve cann't work, but the others work normally | Check the circuit and coil | Replace the accessories | |
| All the valves cann't be closed, leak, Das dome no pressure | Y - valve, some valves leak who connect with the same dome, Cause the feint that all the valve leaking. | Check if leaking | |
| Z - valve,inlet and out let installed opposite | Re-install | ||
| Some valves cann't be closed,leak | There is dirt or debris on the diaphragm, moving iron core cann't move. | Check the diaphragm, and check if the diaphragm is broken, check the moving iron core and air locker | |
| A valve closed slowly | The diaphragm orfice been blocked | Dredge the diaphragm orifice | |
| Some valves leak, diaphragm cann't be closed tightly and the valve keep open | There is dirt or debris on the diaphragm, Pilot broken and moving iron core cann't move. | Check the diaphragm, and check if the diaphragm is broken, check the moving iron core and air locker, replace the accessories if neccessory | |
| Coil is hot and burn | Electricity turn on long time | Check the control systerm | |
| Valve don't work with the electricity | Diaphragm broken or diaphragm orfice been blocked | Replace the accessories in time | |
| When the temprature is below -20℃, maybe the valve will leak or cann't be open | Ice in the valve because the low temprature | Pay attention to maintaining proper temprature | |
| Use Period | Work pressure must be strictly controlled to within 0.2-0.6MPa and being stable relatively. | ||
| Before the valve installed, it is necessary to completely clear away any impurities in the gas dome | |||
| Compressed air must be clean and dry air supply | |||
