Direct-Acting 3 Way solenoid valve has three ports and two internal orifices one inside the valve body and one at the end of the armature tube. The moving armature has two seals one at each end, when one orifice is open the other is closed. When the solenoid coil is energized, the armature moves and the position reverses. Hence the description 2 position.
The image below shows a 3-way, 2 positions normally closed valve. With the coil de-energized, the armature spring holds the lower armature seal tightly against the lower orifice and shuts off flow. Port 2 is exhausted through Port 3. When the coil is energized, the armature is pulled into the coil and the orifice at Port 3 is sealed off by the armature top seal. The media now flows from Port 1 to Port 2.
