A solenoid valve in a watering system is an electrically operated valve that controls the flow of water through the irrigation lines. The valve is activated by an electrical signal from the irrigation controller or timer, which sends a current to the solenoid. This current causes a magnetic field to be generated, which in turn moves a plunger or piston inside the valve to open or close it. When the valve is open, water flows through the system; when it's closed, the water supply is shut off.

    This type of valve is widely used in sprinkler and drip irrigation systems for residential, commercial, and agricultural purposes. Its design makes it ideal for situations where precise control of water flow is required. Solenoid valves are available in various sizes and configurations, allowing them to be used in different watering systems, from small gardens to large agricultural fields.
