Spotlight on Innovation: LHL Series Latching Solenoid Valve

Published On: May 11th, 2021

The persistent demand for smaller, lightweight, more portable products is compelling companies to integrate new, advanced technology into their designs without compromising reliability. These products must also include ultra-low power components to meet certain battery life requirements, which makes a latching solenoid valve a much better option than using a typical spike and hold electrical drive for conventional solenoids.

The LHL Series Latching Solenoid Valve from The Lee Company offered by DenisDePloeg is a compact control valve that features ultra-low power consumption (as low as 5.5 mJ/switch) and low heat dissipation. Available in a 2-port or 3-port configuration, this magnetically latched solenoid valve requires only momentary pulses of current to switch to and remain in each flow state. The advantage of a latching solenoid valve is that it doesn’t consume power, generate heat or produce electrical noise when held in a specific flow state for an extended period of time. These features, coupled together with a design that provides reliable bi-stable switching performance in the smallest footprint possible, is ideal for battery power applications in respiratory therapy, molecular diagnostics, environmental monitors, and patient simulators.

The LHL Series valve is 100% functionally tested for performance and designed with materials that will ensure consistent, long-term operation. Available in different mounting styles and material options, performance characteristics can be further optimized to meet specific application requirements.
