Bray Controls has unveiled the Series 92/93 actuator, which features two independently adjustable travel stop screws and a cam on the output shaft to permit precise bi-directional adjustment of actuator movement in both open and closed positions for quarter turn valves. Available in two versions—double acting and spring return—the rack-and-pinion, opposed-piston actuator are intended for on-off and throttling applications. It offers a maximum pressure of 140 psig and temperature ranges of -40F to +200F. For more information, go to www.bray.com
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
