Tips: If solenoid valve doesn’t work after energized, how to do?
There are some possible reasons for this problem:

• Whether the power supply is connected well.
• Whether the power voltage is within the working range.
• Whether the coil desoldering.
• The coil is short circuit.
• Whether the working pressure differential is proper.
• The fluid temperature is too high.
• Extraneous matters make the valve blocked.
• The liquid is too sticky, the use is too frequent and the service life is up.

Aiming at the above causes, there are some suggestions listed one by one for your reference.

1. Reconnect the wires and the connector assembly.
2. Regulate the voltage to the right scope.
3. Re-welding the coil.
4. Change a new coil.
5. Adjust the pressure differential or replace if necessary.
6. Update an appropriate solenoid valve.
7. Clean out; if the seal is broken, change it.
8. Change a right solenoid valve.
