LGV Series Genvi Solenoid Valves

The LGV Series, genvi™ solenoid valves, are a new generation of versatile and innovative 3-port control valves offering high flow rates, low power and low leakage in a miniature, 10 mm package. Utilizing innovative manufacturing techniques, this novel family of valves is designed to offer application versatility and unmatched reliability in applications flowing air and mild gases.

The new genvi solenoid valves are ideal for molecular diagnostics, oxygen delivery, environmental monitors, compression therapy, breath analyzers and numerous other applications where high flow and low power cannot be sacrificed for size and reliability.

The Lee Company also offers customized valve performance and manifold solutions to meet specific application requirements, along with several fully-assembled genvi accessory kits and components for prototype ease.
