A quick and simple guide to troubleshooting your solenoid valve. The possible causes for your valve not closing correctly are listed below alongside instructions of how to resolve the issue. Lift the solenoid coil slightly (do not remove completely as an a.c. coil will burn out quickly) to feel if there is residual magnetic field.
Here are some common problems that can occur in these parts. 1. Valves Do Not Open Solenoid valves may not open because of power failure, uneven pressure, wrong voltage, dirt under the diaphragm, corrosion, missing components, or a burnt coil. However, since there are so many causes, you must try to narrow down the problem in order to fix it.
Solution: replace the solenoid valve coil. Fault phenomenon: If the solenoid valve has a plug and socket connection, problems may arise with the metal spring of the socket or the wiring of the plug (such as connecting the power line to the ground wire), preventing power from reaching the coil.
Long Duty Cycles: Continuous operation without sufficient breaks can cause the coil to heat up. Faulty Coil Design: Poorly designed coils with inadequate heat dissipation capabilities can lead to excessive heating. In some cases, the solenoid valve’s coil can burn out completely, rendering the valve inoperable. Coil burnout can occur due to:
In case of damage, such as torn diaphragm for pilot solenoid valves, replace the affected part. Install a missing component. This problem can result from inadequate pressure, damaged components such as the armature and tube, dirt on the diaphragm, valve seat, or tube, corrosion, and missing parts.
If the loud hum or buzz doesn’t subside, use a rectifier unit in the valve circuitry to correct the alternating current noise. Make sure the manufacturer specifications match the flow rate of the medium or the source pressures. Incompatibility is often the issue, and which can only be corrected by installing the right solenoid valve.
