This 12V normally closed solenoid valve controls water flow through a 1/2″ (DN15) inlet and outlet. It remains closed when unpowered and opens when 12V is applied — no polarity distinction is required. Pair it with a Gravity Water Flow Sensor (1/2″) for real-time flow monitoring in automated systems.
Built with a stainless steel spring and rated for at least 200,000 cycles, the valve is designed for long service life. The valve terminal direction can be adjusted to suit your plumbing layout. It operates within a working pressure of 0.02–0.8 MPa and can withstand up to 2.0 MPa static pressure.
Key Features

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
