GENVI™SOLENOID VALVEIntroducing the genvi™ LGV Series control valves, a new generation of versatile and innovative 3-port solenoid valves, offering high � ow rates and low power in a minia-ture, 10mm package. Utilizing innovative manufacturing techniques, this novel family of valves is designed to offer application versatility and unmatched reliability at an economical price point.

The genvi solenoid valve challenges the limitations of current � uidic technologies by allowing designers to use a miniature, low power solenoid valve without compromis-ing system-level � ow rate requirements. The new valve is capable of achieving minimum � ow rates of 30 to 40 SLPM at 15 psid, and its spike and hold drive pro� le results in ultra-low power consumption (318 mW) during continuous duty opera-tion. This reduces system-level heating and improves battery life, making it ideal for challenging power budgets.

The new genvi solenoid valves are ideal for molecular diagnostics, oxygen delivery, environmental monitors, compression therapy, breath analyzers and numerous other applications where high � ow and low power cannot be sacri� ced for size and reli-ability. Contact your Lee Sales Engineer for additional technical assistance andapplication information.
