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.

How do I fix a faulty solenoid valve?

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.

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.

What causes a solenoid valve to burn out?

(3) Another potential cause of burnt-out coils is water ingress between the coil and armature - Solution - Shield the coil from water or relocate the valve to a dry location. Burnt out coils are usually the most common problem we see with solenoid valves, this is mainly due to sediment or debris entering the media or the media containing particles.

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.

Can a solenoid valve be scraped?

The inside of a solenoid valve is machined to a high tolerance. Scraping the inside of a solenoid valve could cause damage - never clean by scraping with sharp tools. There is also a need to consider if the fluid is reacting with the valve construction materials causing corrosion. An alternative construction of the valve may be required. (2)
