A solenoid valve in a watering or irrigation system is an electrically operated valve that controls the flow of water through pipes to various sections of a garden or landscape. It is an essential component in automated irrigation systems, allowing the system to turn on or off the water flow based on the controller’s instructions.

How it Works: Electrical Signal: The solenoid valve is controlled by an electrical signal, typically from a controller or timer. This signal activates the solenoid (a coil of wire), which creates a magnetic field. Opening/Closing: The magnetic field pulls or releases a plunger inside the valve, opening or closing the water passage. Water Flow Control: When the valve opens, water flows through the irrigation system, and when it closes, the flow is stopped. This allows for precise control over when and how long water is delivered to different areas. Applications: Automated Irrigation Systems: Used in gardens, lawns, parks, and agricultural irrigation systems.
