Installation & Commissioning |
Not all the valves can be opened;
But the pilot part is running |
Check whether the air tank pressure is too low | Check and prevent air leakage |
| Some valves cannot run while others can | Check the line connections and solenoids of the valves | Replace relevant parts | |
| Not all the valves can be closed, there is air leakage;
The air tank pressure cannot be established |
The air inlets and air outlets of the valves are reversely installed | Install the valves again | |
| Some valves cannot be closed;
There is air leakage |
There are foreign matters on the diaphragms;
The armatures are seized |
Clean the diaphragms and check whether they are complete;
Check the armatures and the air plugs. |

Using |
Valve closing is slow | The diaphragm orifices are blocked | Unblock them |
| Some valves leak;
They often open; Their diaphragms cannot be closed completely |
There are foreign matters on the diaphragms;
The pilot parts are damaged; The armatures are seized |
Clean the diaphragms and check whether they are complete;
Check the armatures and the air plugs; Replace relevant parts promptly |
|
| There is solenoids heating or burning | The valves have been powered on for a very long time | Check the operating status of the control system | |
| There is voltage but the valves cannot run | Diaphragm is damaged;
Pilot opening is blocked |
Replace relevant parts promptly | |
| The ambient temperature is low;
The valves leak cannot be opened |
Ambient air temperature is too low;
Valve internal frozen. |
Keep a promptly high temperature |
