Abstract: One of the stumbling blocks for successful miniaturization and commercialization of fully integrated micro fluidic systems was the development of reliable micro valves. In this study, a micro valve is designed and analyzed by employing two analytical software’s namely ANSYS and FLUENT. This work gives also a brief overview of micro valves, actuation mechanisms and focuses on piezoelectric as one type of actuation mechanisms. Applications of the micro valves include flow regulation, on/off switching and sealing of liquids, gases or vacuums. Even though great progress has been made during the last 20 years, there is plenty of room for further improving the performance of existing micro valves. Results showed that maximum displacement is at the forward of the beam and FLUENT software demonstrated the logical response about behavior of fluid passing through channel of the micro valve system.
