The Lee Company, for over 50 years the only authority in Microhydraulics. 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.

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

The Lee Company sales and engineering staff are eager to help you in solving your fluid control problems with special products that fill your needs.
