High Flow Solenoid Valves
For more demanding applications, our high flow solenoid valves are available in 2-way, 200 Lohms, and 3-way, 300 Lohms configurations. Both are two-stage poppet designs in a miniature package. These valves are available in normally open and normally closed and single or dual coil configurations for 3000 psi system pressures.

Dual Metering Flow Control Valves
The Lee Company’s dual metering flow control valves are two-way restrictors that allow a designer to specify a different metered flow rate in each direction. These valves are ideal for high-pressure hydraulic applications with system pressures up to 5000 psi. They feature all stainless steel construction for durability and long life and are available in 0.187 and 0.281 inch diameter models. Each Lee Dual Metering Flow Control is 100% tested in both flow directions to ensure reliable, consistent performance.
Because each direction can be specified differently, our dual metering flow controls can achieve a nearly infinite combination of metered flow rates. As such, all of these components are supplied as custom items to meet the specific needs of an application.

Selective Shuttle Valves
This is our standard non-biased loose-ball design. Available in 0.187, 0.281, 0.375, and 0.500 inch diameters, these are the most economical configuration. The maximum shuttling pressure is just 1 psid. The valves are rated for leakage of fewer than 1 mL per minute.
Lee Components in Unions
Virtually every 0.187, 0.250, and 0.281 inch diameter Lee insert is offered already installed in appropriately sized flared, flareless, or dynamic beam seal unions. These unions are made of 304 stainless steel (code “J” in military standards) or 6AL-4V Titanium (code “T”). All Lee Unions have a unique hex wrench arrangement to distinguish them from simple unions and permanent external marking to identify the insert.
The configuration of these unions has been carefully chosen to accommodate most of the 0.187, 0.250, and 0.281 inch Lee inserts, and yet maintain both minimum envelope and weight. These units incorporate the high-root radius UNJF threads to minimize stress concentrations with Class 3A tolerances. All fitting-end dimensions are, except for the internal diameters, in general accordance with the appropriate AS4375E4 and E6, AS4395E04 and E06, and AS85720/1-04 and −06 specifications.
Every Lee Union with an insert installed is proof pressure tested; flared and flareless to 6000 psid and dynamic beam seal to 16,000 psid. Maximum working differential pressure is a function of the particular Lee insert specified (refer to the appropriate insert section).
