Product Groups

The Lee Company is organized into three separate divisions; Precision Hydraulics, Electro-Fluidic Systems (EFS), and Industrial Microhydraulics (IMH). Within each division there are one or more product groups, each with their own dedicated engineering, manufacturing, and sales team working together to provide innovative products and first class service. This structure allows us to be very responsive to our customers, offering solutions to solve difficult fluid control problems.

The six Precision Hydraulic product groups supply expansion plugs, high pressure solenoid valves, single and multi-orifice restrictors, nozzles, safety screens, check valves, relief valves, flow controls and shuttle valves to a wide range of industries. These include hydraulic and pneumatic applications on commercial and military aircraft, spacecraft, missiles, naval vessels, machine tools, downhole oil tools, power generation equipment, high performance race cars, motorsports, etc.

The three Electro-Fluidic Systems (EFS) product groups produce high quality miniature solenoid valves (conventional and chemically inert models), high speed micro-dispense valves, atomizing and dispense nozzles, fixed and variable volume pumps, integrated fluidic manifolds, inert tubing and fluid control components and custom engineered designs. These products are typically used in medical and scientific instrumentation, analytical and clinical chemistry, in vitro diagnostics, drug discovery and ink jet printing applications.

The Industrial Microhydraulics (IMH) Division was established to adapt proven design concepts to meet the higher volume production, performance, and cost requirements of automotive, industrial hydraulics, and medical applications. These products include a wide variety of plugs, valves, restrictors, and safety screens designed and manufactured for ease of automated installation, which is of paramount importance to these industries.
