The Lee Precision Micro Hydraulic product groups design, build
and supply fluid-control components to a wide range of industries.
Applications include hydraulic and pneumatic systems in commercial
and military aircraft, spacecraft, missiles, naval vessels, machine
tools, down-hole oil tools, power generation equipment, race cars
and more.
The Lee Company, for over 50 years the only authority in Micro hydraulics.
Components from less than 0.01 in up to 1.0 in diameter, and from
0.1 to 28 grams. We help designers achieve the size and weight reduction
they need, with operating pressures to 8,000 psi. We also take
the time for 100% inspection and testing. This kind of care results
in the high reliability and long life for which Lee components are
noted.

SPECIAL PRODUCTS :- |
The Lee Company offers many miniature flow control
components other than the standard products detailed above. In fact,
approximately 50% of all Lee products are special or custom items
designed to meet the requirements of a specific application. The majority
of these special products are minor variations of standard products
and may differ only slightly in: lohm rate, cracking pressure, leakage,
flow testing, materials etc. The remainder are uniquely different
from the 'standards' described above and include: |
|
- threaded HI-BAR Lee Plugs
- air assisted atomising nozzles
- gas turbine engine fuel nozzles
- transmission/gearbox lubrication nozzles
- eductors or 'jet pumps'
- higher temperature and higher flow and check valves
- zero-leak relief valves
- bypass valves
- flow fuses and vapour vent valves
- mechanically actuated and indicating valves
- absolute upstream pressure regulators (pneumatic)
- HI-BAR safety screens of almost any configuration
- higher temperature and higher flow solenoid valves
