Spirax's newest valve works with steam, water, gases and other liquids at up to 204C (400F), and a maximum pressure of 27 barg (400 psig). It comes in a two and three-way configuration. The three-way version works in applications that combine two fluids or diverting a single fluid for temperature control, while the 2-way plug/stem models can be replaced without removing the valve or actuator. All versions come in ˝-inch to 2-inch body sizes, and has reliable shut-off, using long-life stem seals and one-piece plug/stem design and non-threaded seat. It is built on a cast bronze body, a nitrile-reinforced rubber diaphragm and 300-series stainless steel head, stem and seat.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
