Good quality membranes shall be selected and used for all the
valves , with each part checked in each manufacturing procedure ,
and put into the assembly ling conforming to all the procedures ,
Every finished valves shall be taken the electriferous blowing test
.
| Use period | Failure phenomena | Possible Reason | Troubleshooting |
| During installation and commissioning | The valves cannot all be opened, but the leading part does act. | Check the gas dome pressure to see if it is too low. | Check the leakage |
| Some valves do not work, but the others are normal. | Check the valve coil connection and coil | Replace the accessories |
| The valves cannot all be closed. There is leakage. There is no way
to establish a gas dome. | Y-valve. Some valves for the same gas dome are leaking, thus
causing leakage for all the valves. | Check the leakage |
| Z-valve. The valve inlet and blowing muzzle are installed
backwards. | Re-install |
| Some valves cannot be closed. There is leakage. | There is some dirt or debris on the membrane, ii is blocking the
moving iron core. | Clean the membrane and check that the membrane is complete. Check
the moving iron core and air lock. |
| A valve closing is slowly. | The membrane orifice is blocked. | Dredge the membrane orifice |
| During use period | Some valves are leaking. The membrane cannot close tightly and the
valve is always open a little. | There is some dirt or debris on the membrane, the leading part is
damaged. Moving iron core is blocked. | Clean the membrane and check that the membrane piece is complete.
Check the moving iron core and the air lock. Replace the
accessories if necessary. |
| Coil is hot and burned out. | It has been turned on for too long. | Check the working condition of the control system. |
| Voltage exists but the valve does not operate. | Membrane is damaged and the orifice is blocked. | Replace the accessories in time. |
| Ambient temperature is below -20℃. The valve is leaking and cannot
open. | Ambient temperature is too low and here is frost in the valve. | Pay attention to insulation and maintaining proper temperatures. |
