This study was conducted to analyze the special quality of a very low power consumption type of pneumatic on-off micro valve, and to numerically investigate its flow characteristic depending upon a change in stroke. As a result, it was identified that an enough electromagnetic force (2.4N) acted on the solenoid so that the poppet of the micro valve might run a stroke (0.3 mm) at the high response speed (5ms), and that the yoke caused no magnetic force to be emitted. It was identified that the dynamic presstre acting on the poppet wall was little reduced when the poppet stroke was 0.4 mm or less, but that as it got to be beyond 0.4 mm, it was remarkably reduced and when it was 0.8mm, it went down to 40%.
