If you are experiencing problems with solenoid valves or just like to be prepared for unexpected occasions, you are just in the right place! In this blog, we will brake down the three most common solenoid valve problems that can save you a lot of time.
Before we become experts on solenoid valve problems, we must get down to the basics. Let's take a look at what exactly is a solenoid valve and what is the purpose of it.
What is a solenoid valve?
A Solenoid valve is used to control liquid or gas flow in system. These valves are used for shutting off, release, mix or dose liquid or gases. Solenoid valves can be different types such as: 2-way, 3-way or other.
Below is a list of 3 most common problems, which can appear during using solenoid valves.
We suggest you make yourself a checklist!
1. Solenoid valve doesn’t open / close properly
- Check power supply and make sure voltage and frequency are correct. Also check the connections.
- Check if there is no dirt/corrosion under diaphragm, coil doesn’t burn out or not missing components
- Check if flow direction matches with the indicators on the valve body or matches within limits as specified in the valve manual.
2. Coil burned out, melted or cold with power on
- Check if the power supply is correct and the coil can dissipate heat by ventilation. Install a new coil and never power the coil when not mounted on the valve.
- Check for moisture within and replace if necessary. Replace any damaged or bent armatures as well, and check media compatibility with your valve. Don’t forget to move solenoid valves into cooler areas or you may increase ventilation around valves and coil.
3. Solenoid valve leaks
- Check if its not damaged or worn seals, o-rings, membranes and if necessary replace it.
- Check if there are not inside valve orifices tiny particles of cuttings, sand, and rust. Carefully clean all parts and make sure the pipes are clean.
