A water irrigation solenoid valve is an electrically controlled valve to regulate the flow of water. By applying a voltage over the coil, the valve opens and the liquid can flow through. Solenoid valves are also called electromagnetic valve, water valve, electric valve or electro valve.

How do I know if my sprinkler solenoid is bad?
Signs that Your Sprinkler Valve Solenoid is Bad
- Never-ending water: The valve solenoid may get stuck open, allowing all or a trickle of water through at all times.
- Water leaks: High pressure from a broken solenoid can put a lot of stress on your sprinkler system and burst small or large leaks throughout it.
How does a water sprinkler solenoid valve work?
A small orifice in the diaphragm allows the water to flow through to the upper chamber between the diaphragm and the bonnet. The water continues to travel on through a port in the bonnet to the solenoid area. The solenoid has a light spring loaded metal piston that, when the valve is closed, covers the inlet port hole.
What is the purpose of a solenoid valve?
The definition of a solenoid valve is an electro-mechanical valve that is commonly employed to control the flow of liquid or gas. There are various solenoid valve types, but the main variants are either pilot operated or direct acting.
What causes sprinkler solenoid to fail?
When a solenoid valve (also called an electric valve or automatic sprinkler valve) fails to close it is almost always because something is stuck inside it. This might be a grain of sand, a small twig, a insect, or even a tiny snail. To fix the valve you need to disassemble and clean it.
How long do irrigation solenoids last?
“But, if it’s a good quality valve, it should last 12-15 years out in the field.”
How do you test a sprinkler solenoid?
Valve Test Procedure:
- Turn off the water supply to the irrigation system using an isolation valve.
- Disconnect the solenoid wires from the controller.
- Using and multimeter test the number of ohms through the solenoid. 20-60 ohms – Good.
- If solenoid tests Good, then the solenoid is OK.
What position should sprinkler valves be in?
There should be two, usually blue handled, ball valves (one on the side closest to the house and one on the side going to the irrigation system). Both should start in the closed position (perpendicular to the pipe).
Where are solenoid valves used?
A solenoid valve is an electrically activated valve, typically used to control the flow or direction of air or liquid in fluid power systems. Solenoid valves are used in both pneumatic and hydraulic fluid power systems, and most often in either poppet or spool configurations.
Can you repair a solenoid?
Serving as a powerful relay switch, the solenoid functions as the initial starting device for the vehicle. Replacing the starter solenoid with a new starter does not always have to be done. The solenoid lends itself to repair just like any other component, and savings can be realized by doing so.
Where is the sprinkler solenoid located?
Often the valves are located inside one or more in-ground valve boxes. The tops of these boxes will be at ground level, and these, too, are usually fairly easy to spot and access. The valve box, or sometimes the valves themselves, are sometimes buried underground.
