The 30-mg device requires a momentary 1-msec pulse to switch the state (5 Vdc to open, 5 Vdc to close). The valve's reliable bistable performance and quiet operation make it suitable for compact battery-powered pneumatic applications such as air piloting, lab automation (lab-on-a-chip), and power-sensitive OEM flow-switching devices.
