For guys who are interested in pneumatic system, hydraulic system, inflation equipment, or air compressing, this is a really practical valve for you. It can be used to change the direction of the air outlet, also can 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). You can determine which interface to be connected to the common interface by powering on and off the valve.
