Control Valves for Diagnostics

Miniature Control Valve Designs for Diagnostics Applications

Control valves are used to flow air or gas through pneumatic equipment. Our designs are available in 2-way or 3-way configurations and different mounting styles, and their compactness makes them ideal for portable devices. In addition, we offer magnetically-latching solenoid valves that consume far less power, which helps conserve energy in battery-powered applications.

LHD Series

LHD Series valves are compact, 7 mm control solenoid valves that offer superior performance across an extensive cycle life. With a flow capacity of up to 450 Lohms, power as low as 550 mW, and leakage less than 50 µLPM, these valves maximize control performance without compromising reliability.

LHL Series

LHL Series valves are compact, 7 mm magnetically latched control solenoid valves that feature ultra-low power consumption (as low as 5.5 mJ/switch) and low heat dissipation. Ideal for battery-powered applications flowing air or gas, these valves require only momentary pulses (10-30 ms) of current to switch to and remain in each flow state. While being held in a specific flow state for an extended period of time, these valves don’t consume power, generate heat, or produce electrical noise. In addition, LHL Series valves provide reliable bi-stable switching performance in the smallest footprint possible.

LHQ Series

LHQ Series valves are compact, 7 mm quiet operation control solenoid valves that feature whisper technology to reduce actuation noise. When a typical solenoid valve is energized, there is an inherent clicking sound caused by the metal-to-metal contact of the moving armature and stationary core. With a low sound profile that is 50% quieter (≤ 37 dBA) than our already best-in-class LHD Series solenoid valve, this reliable design is ideal for bedside applications flowing air or gas.

genvi® LGV Series

genvi LGV Series valves are 10 mm, 3-way control solenoid valves featuring high flow, low leakage, and ultra-low power consumption. They were designed using innovative manufacturing techniques that provide unmatched reliability at an economical price. With a flow capability of up to 200 Lohms, power as low as 318 mW, and leakage less than 25 µLPM, genvi valves are ideal for high flow pneumatic diagnostics applications flowing air or gas.
