DFRobot DFR0866 6V 2-Position 3-Way Air Valve for Arduino is a practical valve for pneumatic systems, hydraulic systems, inflation equipment, or air compressing. The device can also be used to change the direction of the air outlet. The DFRobot DFR0866 can also be used as a valve switch. Like a relay, it has a common interface (COM), a normally open interface (NO), and a normally closed interface (NC). The user can determine which interface to be connected to the common interface by powering the valve on and off.
