| fault |
Possible reasons |
Troubleshooting methods |
| No liquid flow |
Liquid pressure too low |
Increase the liquid pressure of the liquid storage device |
| The operating pressure is too low |
Raise the air pressure of the valve controller to70 psi |
|
| Valve not working |
Check the valve pressure of the valve controller |
|
| Liquid solidifies inside the valve chamber |
Remove the valve and thoroughly clean it |
|
| Stroke control adjustment does not work |
Rotate the stroke control knob counterclockwise (do not exceed the "line mark") |
|
| Unstable liquid flow |
Unstable liquid pressure |
Ensure a constant liquid pressure |
| The operating pressure of the valve is too low |
Raise the valve operating pressure of the valve controller to70 psi |
|
| The opening time of the valve is inconsistent |
Check the valve controller to ensure it provides stable air pressure output |
|
| Gas is trapped in the valve cover |
Discharge gas from the valve |
|
| After the valve is closed, liquid still flows out and stops after a period of time |
Gas is trapped in the liquid shield |
Discharge gas from the valve |
| Spray interval is too short |
Increase the spray interval of the valve controller |
|
| The liquid flows through the nozzle but does not |
The atomization pressure is too low |
Improve the atomization pressure of the valve controller |
| Continuous dripping |
Nozzle andDelrin®The base is dirty |
Thoroughly clean the nozzle and base |
| Delrin®The base is worn or damaged |
Replace worn or damaged parts |
|
| Liquid pressure exceeds100 psi |
Reduce the liquid pressure in the liquid storage container until the dripping stops |
|
| Valve installation error |
Remove the valve and reinstall it according to the instructions |
