12V Solenoid Valve - 3/4
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.
