MK series valves - New PowerTube™ technology
Pendell, PA (September 2007) – Co-ax valves' PowerTube ™ technology is built into each of its MK series valves. The fast (25 milliseconds depending on size) bubble-tight positive shut off is ideal for applications where leaks simply cannot be tolerated, or where leak-testing is a prerequisite. The co-ax MK 10 is available as a normally closed, or, normally open valve. And because the valve is engineered to accommodate pressure imbalances in either direction there are no check valves...

Open Cell Metal, Carbon & Ceramic Foam Materials
are a three-dimensional, perfectly packed array of similar sized bubbles where each bubble has the maximum volume for the minimal surface area and surface energy. Given these common physical constraints, each bubble in the array is typically a 14-faceted polyhedral or solid shape called a tetrakaidecahedron. Once the foam is solidified, the thin membrane in each of the 14 facets or windows is removed by a reticulation process, creating an "open cell", and leaving only the thick outer perimeters of the window...
