This unusual clean unused automotive surplus item should have lots of interesting vacuum and low pressure (8 PSI or lower?) robotics uses. It is a three-way ambient dump valve, but works BACKWARDS from normal.

When DEENERGIZED, the two upper pipes are connected together. When ENERGIZED with 12 vdc at 200 ma, the left pipe is blocked and the right pipe vents to ambient through a sintered brass filter.

Should be perfect for custom vacuum pick-and-place tools. On any other place you want to "let go" when actuated.

Approximate shipping weight per valve: a few ounces.
