Solenoid Valve-DN15

DFRobot 12V Solenoid Valve (DN15) provides reliable electronic control of liquid flow for automation projects and water management systems. This motor‑driven water control valve integrates a DC motor and reduction gearbox into a compact assembly capable of handling up to 1.0MPa static pressure. Three control wires enable straightforward open/close operation while maintaining the last valve state during power loss. Designed for robotics prototypes, smart irrigation setups, and IoT fluid control systems, the automated liquid control module pairs easily with microcontrollers such as Arduino through relay switching for programmable water flow management.

Dual Control Mode with Simple Wiring

This electronically actuated DN15 valve uses a clear three‑wire control interface for reliable switching. Blue wire connection to the positive terminal triggers the open action, while the red wire initiates valve closure. The yellow wire functions as the shared ground line. Manual operation remains possible when external power is disconnected, allowing mechanical opening or closing without electrical control. Such hybrid operation makes the fluid control module suitable for automated systems that occasionally require manual override during maintenance or emergency situations.

Integrated Gear Motor with High Torque Output

A built‑in DC motor and metal reduction gearbox deliver strong torque between 30–60kg·cm, enabling stable actuation even under significant pipeline pressure. The compact integrated structure reduces installation complexity while maintaining reliable motion control. Compared with simple electromagnetic valves, the geared motor mechanism produces lower operating noise and smoother valve movement. This mechanical design supports long‑term deployment in automation environments including irrigation controllers, aquaculture systems, and smart plumbing prototypes.

Reliable Sealing and Anti‑Interference Design

A sealed motor housing enhances durability by protecting internal components from moisture and environmental contaminants. The automated water valve demonstrates stable electrical performance, strong sensitivity to control signals, and resistance to electromagnetic interference commonly present in automated systems. Withstanding up to 1.0MPa static pressure, the liquid control hardware remains dependable in pipelines, tanks, or water circulation installations where stable sealing and pressure tolerance are essential.

Easy Automation with Relay-Based Control

This motorized water flow controller integrates smoothly with relay modules such as the Gravity: Digital 5A Relay Module, enabling programmable open and close timing through microcontroller platforms. Combined with sensors and control boards, the valve becomes a core component in automated irrigation, smart water tank management, and precision fluid distribution systems. Flexible electronic switching makes the valve well suited for IoT experiments, environmental monitoring setups, and engineering prototypes requiring controlled liquid flow.
