Valve Apparatus and System

Abstract

A bistable valve. The valve includes an interior cavity; a first pressure source; a second pressure source; a first post connected to the interior cavity at a first end of the interior cavity; a second post connected to the interior cavity at a second end of the interior cavity; a magnetic shuttle located within the interior cavity; a first electromagnetic coil disposed about the first post; a second electromagnetic coil disposed about the second post; wherein when the first electromagnetic coil is energized, the first electromagnetic coil supplies a magnetic charge to the first post and actuates the magnetic shuttle to move towards the first end of the interior cavity towards the first post and seal the first pressure source.
