Quiet Operation HDI 3-Port Solenoid Valve - 1

ELECTRO-FLUIDIC SYSTEMS PRODUCT DATA SHEET ■ Low Actuation Noise ■ 50% Quieter Than Our Already Best in Class HDI Design: <37 dBA ■ Compact Size ■ Light Weight: Less Than 4.5 grams ■ Leakage: Less Than 50 SpLPM at 15 psid (air) ■ Operating Temperature Range: 60°F to 120°F The Lee Company’s LHQ Series Quiet Operation HDI is a miniature 3-port solenoid valve designed to significantly reduce actuation noise. A typical solenoid valve has an inherent clicking sound when energized, which is caused by the metal-to-metal contact of the moving armature and stationary core. This Quiet Operation design uses whisper technology to significantly reduce actuation noise by 50%, providing a sound level measurement of less than 37 dBA when measured at a distance of 12 inches and a valve cycle frequency of 10 Hz. Refer to the table below for relative sound pressure levels. This valve joins the expansive HDI valve product platform and is ideal for medical applications flowing air or compatible gases such as patient simulators, dialysis machines, patient monitors, and other bedside medical devices. Performance parameters can be optimized for specific applications. Contact your Lee Sales Engineer for technical assistance and additional information regarding quiet design options.
