This 12V DC solenoid valve controls water flow through a 3/4″ threaded inlet and outlet. It is normally closed — fluid is blocked until 12V is applied to the fast-on spade connectors on the solenoid coil. Connect it to a pressurised water source such as a garden hose or mains supply for automated irrigation, filling, or fluid control projects.

This valve requires water pressure to open fully — it is not suitable for gravity-fed systems. It operates at a minimum of approximately 3 PSI and allows around 3 L/min of flow at that pressure.

Key Features

  • Normally Closed Operation – Blocks flow when unpowered, opens at 12V DC
  • 3/4″ Threaded Connections – Standard threaded inlet and outlet for common hose and plumbing fittings
  • Fast-On Spade Connectors – Easy wiring to the solenoid coil
  • Pressure-Operated – Requires minimum ~3 PSI water pressure to open

Ideal For

  • Automated garden and greenhouse irrigation
  • Aquaponics and hydroponics water management
  • Home automation fluid control systems
  • Microcontroller-driven water dispensing projects

Package Contents

  • 1× 12V Solenoid Valve (3/4″)
Important: This is not a gravity-feed valve. A pressurised water source (garden hose, mains supply, or pressure pump) is required — low-pressure pumps may not provide sufficient flow. A relay or MOSFET is needed to switch the valve from a microcontroller.
Tip: Looking for a different size? See the 12V Solenoid Valve (1/2″) or browse our other solenoid valve options.

Jargon buster

Plain-language definitions for the technical terms used above.

Gravity
Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
microcontroller
A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
