This infographic by Tameson.co.uk shows the five most common problems with solenoid valves and ways to fix it. Solenoid valves are very reliable when they are used correctly. However, they can be quite fragile when used with the wrong operating conditions. Malfunctions can occur in a variety of locations, usually they can be repaired rather easily. The most common problem is dirt in the valve, which can lead to several problems. By cleaning the internal parts, this problem can mostly be solved. If the valve does not switch when powered, follow these steps: First, check the voltage and frequency. Match them to the specifications of the coil. Second, feel if the coil stays cold when powered. If so, the coil may be burnt out and the coil needs to be replaced. If the valve still malfunctions, check if the armature is bent. If it is bent, replace the valve. Finally, check if the flow direction corresponds with the valve. More info about solenoid valve failure modes can be found on Tameson.co.uk.

This piece—blending the genres of infographic and diagram—identifies 5 solenoid valve malfunctions. Each item is clearly labeled in the content, and there seems to be a correlating visual distinction with each area of concern. Overall, it's easy to understand what the 5 concerns are from a text perspective; however, for an unfamiliar reader, it might be challenging to understand which visual malfunction is which. This concern could be resulting from the choice of illustration style, which is a less detailed style, or due to a lack of visual relationship between the copy and the illustration. The copy itself also provides some solutions or places to check to confirm if that valve area is malfunctioning. This information is helpful for a reader, but some visual distinction might also help clarify that there's a shift between problem and solution. In general, there's a lot of information here—it just take some time to align what's being shown and what's being read. We'd give this an F.
