How to recognize when the valve isn’t working properly
Solenoid valves can suffer from a few common issues, but these are usually quite simple to address. One of the most frequent problems is when the valve does not open or close completely. This may be due to dirt in the valve seat, a damaged seal, or the coil not receiving enough voltage to properly activate the valve.
Another common issue is a buzzing noise or vibrations from the valve, often indicating voltage fluctuations or loose parts. If you notice leakage through the valve, it may be caused by worn seals, corrosion, or poor installation.
How to maintain them
To keep solenoid valves in good condition, it’s important to perform regular maintenance. Here are a few tips to prevent common problems:
- Filter the medium – Make sure no particles enter the valve.
- Check the coil – Prevent damage by keeping it away from excessive heat and moisture.
- Clean the valve regularly – Especially if it handles dirty fluids.
- Test the valve manually – If your valve has a manual override, use it to check functionality.
When to replace the solenoid valve – and when only the parts need replacing
It can be difficult to know when a valve has reached the end of its lifespan. If the valve feels sluggish or doesn’t respond as it should, even after checking the voltage and cleaning it, it may be time for a replacement.
In many cases, you can extend the valve’s life by replacing certain parts, such as coils, seals, and springs. When the solenoid valve functions as a shut-off valve in a critical system, reliability is particularly important. In such cases, it may be more sensible to replace the entire valve rather than just individual parts, minimizing the risk of future operational issues.
If the valve still doesn’t work after replacing parts, or if it’s too costly to replace all components, it may be more cost-effective to replace the whole valve.
Keep your solenoid valves in top shape
To make troubleshooting easier in the future, it can be a good idea to label valves in larger systems. This way, you can quickly identify and resolve any faults. Keeping spare parts in stock, such as extra coils and seals, can also save both time and money during downtime.
Finally, make sure to document servicing and part replacements to keep track of when the valve was last maintained – this makes planning the next service much easier.
Simple tips for longer lifespan
Maintaining solenoid valves doesn’t have to be complicated. By staying aware of common problems, preventing dirt and damage, and knowing when it’s time to replace parts, you can keep your valves in good condition and avoid unexpected downtime.
