Pulse valve is composed of pilot head, diaphragm and valve aluminum body. The back cavity area of diaphragm is bigger than the front one. The diaphragm is kept at the closed position due to the effect of big pressure.
Electrical pulse controller send input signals so that the electromagnetic armature attracts the moving bar. Unclose the balancing hole to release the pressure gas in the back cavity of diaphragm quickly; the pressure gas in the front cavity holds up the diaphragm to open the passage and the valve starts cleaning.
|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.|
