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
|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.|
