Description
12V Mini Solenoid Valve – 2-Position 3-Way Electric Air/Gas Valve (FA0520F & FA0520E)
This 12V Electric Solenoid Mini Valve is a compact and efficient 2-position 3-way valve designed for air and gas flow control. Ideal for pneumatic projects, automated systems, gas release mechanisms, inflatable systems, and DIY air pump setups.
Available in two variants—FA0520F and FA0520E—this mini solenoid valve allows seamless switching between airflow directions using simple electrical activation. When powered, the valve changes the airflow path, enabling controlled inflation, deflation, exhaust, or vacuum operations.
Its lightweight and durable design makes it perfect for hobbyists, engineers, robotics developers, and automation projects requiring precise, reliable pneumatic control.

How it Works:
- This valve act as closed (blocked flow) when not powered
- When you apply a 12V power supply to the input, the valve gets open and the flow-through valve get started
- Removing the supply voltage again blocks the flow
- This is a two-way valve which means it can flow in both directions
Working Modes of : FA0520F
- When power is ON, 1 and 2 are connected, and 3 is not connected to 1 or 2.
- When power is OFF, 1 and 3 are connected, and 2 is not connected to 1 or 3.
Working Modes of : FA0520E
- When power is ON, 3 and 2 are connected, and 1 is closed.
- When power is OFF, 1 and 3 are connected, and 2 is closed.
