12V Ball Valve DN15 1/2 Inch

This DFRobot motorised ball valve DN15 (½ inch) opens and closes a water pipe with 12 V DC. A DC motor with metal gearbox turns the ball; after switching, the valve keeps its position even without power. A Gravity 5 A relay module is included, so the valve can be controlled directly from an Arduino or another microcontroller.

Caution: It can never be ruled out that the valve or the hose fails during irrigation. We do not cover any costs caused by water damage.

Recommended Accessories:

• 12V DC 4000mA Power Supply AC/DC Adapter 5.5mm/2.1mm Plug
• DC Socket Female Barrel Jack 5.5mm / 2.1mm with Screw Terminals
• Gravity Flow Sensor 1/2 Inch

Features:

• Three wires: blue to +12 V opens, red to +12 V closes, yellow is the common ground
• Keeps its position without power, actuation time 5 to 10 s according to DFRobot
• Wiring according to the DFRobot wiki: relay COM to +12 V, NC to blue, NO to red, yellow to minus. Relay off means open, relay on means closed
• Position indicator on the actuator: «|» closed, «—» open
• Manual operation: pull out the knob on the actuator and turn it
• Brass body with female thread, sealed actuator

Application Examples:

• Automatic irrigation with timer or soil moisture sensor
• Water tank with level control
• Water circuits in aquariums and fish farming
• Shutting off a pipe via smart home control
