Sprinkler valves are essential machines in any lawn irrigation system. Without these magical devices, our yards would be nothing more than wilted and brown patches of grass.

But what exactly are sprinkler valves and how do they work? Let’s dive into the basics of sprinkler valves and explore the inner workings of this powerful device.

Solenoid Activation

The first part of a sprinkler valve is the solenoid, which activates when an electric signal is received. This electric signal turns on or off the flow of water through the valve, allowing you to control when your lawn is watered.

Thanks to this electric signal, it’s easy to automate your lawn’s watering schedule with a timer – even while you’re away on vacation!

Electric Switch

The second part of a sprinkler valve is the electric switch. This switch works in conjunction with the solenoid to ensure that the water supply is cut off when needed.

In addition, this switch also helps regulate the amount of water that flows through the valve, ensuring that your lawn always gets enough water without wasting any excess.

Benefits Of Using Sprinkler Valves

Besides saving time and energy, there are many benefits to using sprinkler valves for lawn irrigation systems:

  1. They reduce water waste by allowing you to precisely control how much water goes into your yard.
  2. They can be set up on timers so that your lawn never goes without water while you’re away from home.
  3. They provide greater flexibility by allowing you to customize your watering schedule according to season or weather conditions.
  4. They are relatively inexpensive compared to other types of irrigation systems.


Sprinkler valves are an essential component of any lawn irrigation system. By controlling the flow of water through their two main components – a solenoid and an electric switch – they make it possible for us to effortlessly automate our yard’s watering schedule with a timer even while we’re away from home!

Not only do sprinkler valves save time and energy, but they also reduce water waste by carefully regulating how much water is being used each time they’re activated – making them an invaluable tool for anyone looking for an efficient way to keep their yard green and lush!
