Common failure and troubleshooting
During installation and commissioning
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.
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.
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
1 . Some valves are leaking. The membrane cannot close tightly and the valve is always open a
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.
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.
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.
