The Lee Company’s new Quiet Operation High Density Interface (HDI) is a 3-way solenoid valve designed to achieve patient comfort by reducing actuation noise by 50%. 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 new quiet operation design uses “whisper” technology to provide a sound level measurement of less than 37 dBA when measured at a distance of 24 inches and a valve cycle frequency of 10 Hz.

Available in face mount, plug-in and ported configurations, the Quiet Operation HDI is ideal for medical applications flowing gas or air, such as dialysis machines, patient monitors, ventilators/respirators and other bedside medical devices.
