Development and Experimental Characterization of a DE Membrane Actuated Valve

Abstract:
Dielectric Elastomer (DE) membrane actuators are lightweight, high energy density systems which show promise for improving the performance of pumps and valve control units. Particularly, the use of DE’s as valve control units offers advantages over traditionally used solenoid valves. Unlike solenoids which draw current continuously when activated, the DE-system draws current only during its initial motion, aside from some very small leakage currents. This means that the DE will use significantly less energy for holding a valve in position than a solenoid would performing the same action. The DE also generates very low heat and runs virtually silent. This work presents a valve which is driven by a DE-system consisting of a diaphragm, or circular, DE and a linear spring. The valve is designed for pressured air and allows a similar volume flow at various pressure drops to industrial valves. An experimental investigation of the performance of the DE valve is conducted, demonstrating an improvement with respect to a solenoid valve with similar characteristics.
