6V 2-Position 3-Way Air Valve for Arduino

2-position 3-way solenoid air valve for pneumatic systems; operates at 6V, 100mA, and is rated for gas media. Changes air flow direction under digital control.

Logical pinout · physical placement not verified

Coil +
6 V DC solenoid coil supply lead; energising the valve switches the common pneumatic port from normally closed to normally open, per DFRobot product page.
Type · PowerVoltage · 6 V DC, rated current 100±10% mA, 0.6 W
Coil -
Solenoid coil return lead for the 6 V DC valve supply.
Type · GroundVoltage · 6 V DC return
COM
Common air interface. DFRobot states the valve has common (COM), normally open (NO), and normally closed (NC) interfaces.
Type · Unknown
NO
Normally open air interface. Connected to COM when the valve is powered according to the product-page relay-style description.
Type · Unknown
NC
Normally closed air interface. Connected to COM when the valve is not powered according to the product-page relay-style description.
