Proportional valves are available in nine orifice sizes ranging from 0.062 to 0.625. All the valves in this line feature a 250 Hz frequency response and a less than 3% hysteresis. The valves perform at low pressure drops and are for medical, industrial control, and alternative fuel applications. An isolation diaphragm separates the working fluid from the coil and armature. This limits the fluid path exclusively to the poppet area, making these valves suitable for both gases and liquids.
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.
