Understanding Irrigation Valves

Before we dive into the process of locating irrigation valves, let’s take a moment to understand how these components work. By gaining a better understanding of irrigation valves, you’ll be better equipped to find and operate them effectively.

Irrigation valves are devices that control the flow of water in an irrigation system. These valves are typically located in valve boxes buried underground, protecting them from the elements. They are designed to open and close to control the flow of water to different zones or areas of your landscape.

There are two main types of irrigation valves: manual valves and automatic valves. Manual valves require physical intervention to turn them on or off. This can be done by manually turning a handle or lever. Automatic valves, on the other hand, are equipped with electronic or mechanical mechanisms that allow them to open and close at predetermined times, often controlled by a timer or irrigation controller.

One important feature of irrigation valves is the solenoid valve. Solenoid valves are electro-mechanical devices that control the opening and closing of the valve. When an electric current is applied to the solenoid, it creates a magnetic field that lifts a plunger, allowing water to flow. When the current is removed, the plunger drops back down, closing off the water flow.

Irrigation valves are typically labeled or color-coded to indicate the specific zones or areas they control. This makes it easier to identify and operate the valves when making adjustments or repairs. It’s important to familiarize yourself with the labeling or color-coding system of your irrigation system to ensure the correct valve is being operated.

Now that we have a basic understanding of irrigation valves, it’s time to gather the necessary equipment to begin the process of locating them. Let’s move on to the next step!
