Structure Drawing

When not energized

Operation description / When not energized

The spool valve (3) is pushed upward with the reaction force of the spring and (1) is sealed while (2) and (3) are opened.
Air flow direction: (1) ⇔ block, (2) ⇔ (3)

When energized

Operation description / When energized

The armature (6) is attracted to the pole piece (5), pushing down the spool valve (3) with the push rod (7). As a result, (3) is sealed while (1) and (2) are opened. At this time, a gap is formed between the armature (6) and the pole piece (5), but the pole piece (5) is attracted to the armature (6) and the two stick together.
Air flow direction: (1) ⇔ (2), (3) ⇔ block
