Characterization of MSMA-based Pneumatic Valves

The deformation range, forces and frequency of the Magnetic Shape Memory Alloys (MSMAs) render them suitable for applicationsin electro-mechanical transducers, used to control pneumatic valves. A fast-operating electro-mechanical transducers canbe designed, whose driving elements should not execute any motion, as they do in valves available to date, and which should getdeformed instead. Utilising the deformation of an element made from the MSMA, the active element of the valves may be shifted, thuschanging the flow orifice. MSMA-based valves can become a new group of electric valves, featuring improved dynamic behavior andbetter resistance to external vibrations.
