120 Series Solenoid Valves

The World's Smallest Solenoid Valve

The Lee Series 120 Solenoid Valve is a 2-way, ultra-miniature, magnetically latched solenoid valve ideal for compact battery-powered pneumatic applications such as air piloting, lab automation (lab-on-a-chip), and other miniature, power-sensitive markets such as fuel cells or for R&D proof of concept projects.

The Series 120 valve sets a new industry standard in reducing space, weight and power consumption.  Measuring just 0.4" long, the valve weighs 300 mg and requires only 1.8 mJ/switch.
