12V Solenoid Water Air Valve Switch (Normally Closed) – 1/2” controls the flow of fluid (liquid or air) and acts as a valve between high-pressure fluid! This liquid valve would make a great addition to your robotic gardening project. There are two ½” (Nominal NPT) outlets. Normally, the valve is closed. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through. The flow rate is ≥1.8L/min when the water pressure is 0.02MPa; the flow rate is ≥20L/min when the water pressure is 0.8MPa.
