Common failure and troubleshooting                                                                                                      

During installation and commissioning

Failure phenomena

1 . The valves cannot all be opened, but the leading part does act.

2 . Some valves do not work, but the others are normal.

3 . The valves cannot all be closed. There is leakage. There is no way to establish a gas dome.

4 . Some valves cannot be closed. There is leakage.

5 . A valve closing is slowly.

Possible Reason

1 . Check the gas dome pressure to see if it is too low.

2 . Check the valve coil connection and coil

3 ( 1 ) . Y-valve. Some valves for the same gas dome are leaking, thus causing leakage for all the valves.

3 ( 2 ) . Z-valve. The valve inlet and blowing muzzle are installed backwards.

4 . There is some dirt or debris on the membrane, ii is blocking the moving iron core.

5 . The membrane orifice is blocked.

Troubleshooting

1 . Check the leakage

2 . Replace the accessories

3 ( 1 ) . Check the leakage

3 ( 2 ) . Re-install

4 . Clean the membrane and check that the membrane is complete. Check the moving iron core and air lock.

5 . Dredge the membrane orifice

During use period

Failure phenomena

1 . Some valves are leaking. The membrane cannot close tightly and the valve is always open a

little.

2 . Coil is hot and burned out.

3 . Voltage exists but the valve does not operate.

4 . Ambient temperature is below -20℃. The valve is leaking and cannot open.

Possible Reason

1 . There is some dirt or debris on the membrane, the leading part is damaged. Moving iron core is blocked.

2 . It has been turned on for too long.

3 . Membrane is damaged and the orifice is blocked.

4 . Ambient temperature is too low and here is frost in the valve.

Troubleshooting

1 . 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.

2 . Check the working condition of the control system.

3 . Replace the accessories in time.

4 . Pay attention to insulation and maintaining proper temperatures.
