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.
The pulse signal disappears and the spring of the armature works
immediately to resume the moving bar so as to close the balancing
hole. The pressure gas in the back cavity of the diaphragm and the
spring work together to close the passage the valve stops cleaning.
The damping hole in the diaphragm functions to damp the airflow
when the moving bar of armature holds up for balancing and to
transit the air to the back cavity as soon as the balancing hole is
shut to close the passage and stop cleaning.

Common failure and troubleshooting
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. |
