Understanding Irrigation Valves

An irrigation valve is a crucial component of an automated irrigation system. It serves as the gateway for water to flow from the main water source to the designated irrigation zones. Understanding how irrigation valves work is essential for efficiently managing your irrigation system.

There are two main types of irrigation valves: manual valves and automatic valves. Manual valves require physical intervention to turn them on or off, while automatic valves are controlled electronically through an irrigation controller or timer.

Manual irrigation valves are commonly found in smaller residential systems or in areas where automatic systems are not readily available. These valves typically consist of a lever or a handle that can be manually operated to open or close the valve.

On the other hand, automatic irrigation valves are more commonly used in larger commercial or residential systems. These valves are controlled by an irrigation controller, which allows for programming specific watering schedules and durations.

Irrigation valves are designed to regulate the flow of water to different zones or sections of your garden or landscape. Each valve is connected to a specific zone, and the controller sends an electrical signal to open or close the valve at the designated time.

It is important to note that irrigation valves are typically installed above ground, usually inside a valve box to protect them from external elements. The valve box provides easy access to the valves and allows for maintenance and repairs if necessary.

Understanding how your irrigation valves function and the differences between manual and automatic valves will help you better manage and troubleshoot your irrigation system. This knowledge will come in handy when you need to manually operate a valve or when you encounter issues that require manual intervention.
