Pneumatic solenoid valve
45 psig THE LEE COMPANY

The Lee Company's line of miniature High Density Interface (HDI) 3-way Solenoid Valves are ideal for applications that demand ultra-low power, low heat and small size. The valves are available in flexible plug-in, ported and face mount configurations, and in several unique designs:

Latching HDI
The Latching HDI is specifically designed for compact, battery powered pneumatic instruments such as portable oxygen delivery systems and environmental gas samplers. The valve is magnetically latched and requires only momentary (10 ms) pulses of current to switch the state. The valve measures just 1.12" long x 0.28" diameter and consumes only 2.8 milliwatt-sec per switch.

Quiet Operation HDI
The Quiet Operation HDI is 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. 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.

Semi Inert HDI
The perfluorinated Semi-Inert HDI is ideal for use in anesthesia delivery, inkjet printing, gas detection systems, reagent delivery and other OEM flow switching applications requiring chemical resistance. The Semi-Inert HDI weighs less than 4.5 grams and features low power consumption (850 mW) and low internal volume (75 microliters).
