KENDRION Miniature Bi-Stable Isolation Valve (BIV)

The Miniature Bi-Stable Isolation Valve (BIV) was designed with size and battery life in mind. Powered metal was used to reduce the footprint of the valve while allowing for integrated mounting features. A diaphragm was used to isolate the fluid from contact with metal. A permanent magnet is used to latch the valve in the open or closed position to reduce the draw on the battery while dispensing. Pins were also integrated into the design to detect when fluid was no longer present and signal the end user when it was time to re-fill the supply fluid. All of this in a package roughly the size of a thumb tack.
