The 6V Air Valve (FA0520E) is a 3-port solenoid valve for pneumatic systems, functioning similarly to an electrical relay. It features a common port (COM), a normally open port, and a normally closed port, allowing you to switch air flow direction by powering the valve on or off.
The valve is rated at 6V but works reliably at 5V. It comes with a pre-wired cable terminated with a 2-pin JST PH connector for easy integration. You'll need an air pump to generate positive or negative pressure — the valve controls which port is connected to the common line.
Key Features
- 3-Port Design – Common, normally open, and normally closed ports
- Relay-Style Operation – Power on/off to switch air flow direction
- 6V Rated – Also works at 5V
- JST PH Connector – 2-pin pre-wired cable for easy connection
How It Works
- Powered: Common (middle) port connects to the plastic end port; metal end port is closed
- De-powered: Common (middle) port connects to the metal end port; plastic end port is closed
Ideal For
- Pneumatic system prototyping
- Inflatable and balloon projects
- Air compression and vacuum systems
- Arduino and microcontroller-controlled pneumatics

Jargon buster
Plain-language definitions for the technical terms used above.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- 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.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
