A 12V DC motorised solenoid valve for controlling liquid flow in automated systems. Featuring a sealed metal reduction gearbox with high torque and low noise, this valve integrates both automatic and manual operation — it maintains its current state when powered off, allowing manual override.
The three-wire control interface (open, close, ground) makes integration with microcontrollers and relay modules straightforward, making it ideal for smart home, agriculture, aquaculture, and other water flow control projects.

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.
- electromagnetic interference
- Electromagnetic interference (EMI) is unwanted electrical noise from nearby devices, cables, or radio signals that can disturb the signals carried in a wire or circuit. Shielding helps reduce this noise, which matters because cleaner signals make data and communication links less prone to errors and dropouts.
- kg·cm
- A torque unit often used for hobby servos, meaning how many kilograms of force the servo can hold at a 1 cm arm length. A higher kg·cm rating means the servo can move or hold heavier loads, but power supply current needs may also increase.
- 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.
- Relay module
- A relay module uses an electrically controlled switch to let a low-power microcontroller control a separate circuit. It matters when switching devices that need different voltages or more current than a microcontroller pin can safely handle.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
