How do you troubleshoot a solenoid valve?

Excessive heat may cause the coil to burn out. If the solenoid valve is part of a fluid system, check and clean the filters or strainers upstream of the valve to prevent debris from entering and causing problems. Effective troubleshooting of solenoid valves involves a systematic approach to identify and address issues.

What happens if a solenoid valve is faulty?

A faulty solenoid valve cannot operate according to requirements. It may not regulate the medium in the system well, which can lead to fluid leaking through the orifice. If the valve’s function is to dose or mix liquid, it can be a disastrous situation. The same case if the valve controls functions where accuracy is paramount.

What if a solenoid valve hums?

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.

What causes a solenoid valve to overheat?

Particles in the fluid can cause vibrations and noise. Ensure the system is properly filtered to prevent contamination. Moreover, high pressure can lead to noisy operation. Verify that the pressure is within the recommended range for the solenoid valve. High voltage or operating it continuously can cause the solenoid coil to overheat.

What happens if a pilot solenoid valve is damaged?

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.

How do I know if my solenoid valve is bad?

Check the solenoid valve coil voltage specifications and those of the power supply. If incompatible change the coil and use one whose voltage requirements are in line with your power source. Solenoid valve voltages vary across different valve types and sizes. Ensure you install the right one for your situation. Inspect the solenoid valve wiring.
