The Lee Company THE CONTINUING STORY OF LEE COMPANY INNOVATION For over 60 years, The Lee Company has pioneered the design and development of miniature fluid control components. Since its beginning in 1948, The Lee Company premise has been to economically solve problems where existing hardware is either not immediately available, or is too cumbersome. The Lee Company continues to set the standards for fluid control components through innovations developed at our Technical Centers in Essex and Westbrook, Connecticut. Electro-Fluidic Systems products are designed and manufactured at our...

The Lee Company PRODUCT GROUPS Lee is organized into nine product groups or “cells” Each product group is comprised . of its own engineering, manufacturing and sales teams working together to provide better service and products. Quicker responses and deliveries, higher quality, lower costs and product innovations to better solve our customers’ problems are direct benefits of this approach. The three Electro-Fluidic Systems (EFS) groups produce high quality miniature solenoid valves (general purpose and chemically inert models), high speed micro-dispense valves, atomizing and dispense...

SOLENOID VALVES Lee’s High Density Interface (LHD Series) Solenoid Valves are designed for applications where space is limited. Featuring small size and light weight without sacrificing performance and reliability, the valves are available in three different styles: plug-in, face mount, and ported. Extended performance versions (Latching, Quiet Operation, Semi-Inert and Lo-Lohm) are also available. These valves are generally used in medical and scientific instrumentation or control applications such as oxygen delivery systems, gas analysis equipment, patient monitors, air calibration...

SOLENOID VALVES Latching Design The Latching design is optimized for applications that demand ultra-low power and low heat making it ideal for portable, battery powered instruments. The valves require only momentary (10 ms minimum) pulses of current to switch state resulting in 5.5 millijoule per switch. The polarity of the voltage on the terminal pins controls the switched position. Quiet Operation Design The Quiet Operation design uses “whisper technology” to achieve patient comfort. A typical solenoid valve has an inherent clicking sound when energized, which is caused by the...
