Drilled Safety Screen, 187 Insert Retained
Lee 187 Insert Retained Drilled Safety Screens combine a Lee locking end with a robust, one-piece screen element. Using the proven Lee Insert Principal (refer to our website, or the Lee Technical Hydraulic Handbook for additional details), these screens allow for a simple installation directly into a fluid passageway. This installation technique locks the screen into the surrounding housing and provides a reliable, leak-proof seal. Capable of handling burst and collapse pressure differentials up to 3000 psi, these screen designs are available in two hole sizes, 380 and 500 micron.

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 Ring Locked Adapters
Virtually all Lee miniature components, including check valves, flow controls, restrictors, and screens, are available already installed or built into Ring Locked Adapters. Design engineers can now take advantage of the unused space in their Ring Locked Adapters to save space and weight in their manifolds.
The Lee Company offers all these products in Ring Locked Adapters with three different tube ends: dynamic beam seal, flareless, and metric dynamic beam seal (8° 30’ lip-seal). Dynamic beam seal and flareless tube versions range in size from −4 to −10 (1/4 to 5/8 inch) and metric lip-seal versions range from 6 to 16 mm nominal tube O.D. Titanium has been selected as the adapter material for the lowest possible weight. All Ring Locked Adapters containing Lee components have blue lock rings to distinguish them from ordinary adapters, and permanent external marking to identify the function of the product inside.

High Flow Pressure Relief Valve
The Hi-Q PRV is designed for applications that require both a high relief pressure and a high flow rate in a line removable unit (LRU). The valve is offered with minimum cracking pressures from 1000 to 5400 psid and flow rates over 19 GPM, and uses a side inlet flow path to minimize the installation boss size and weight.
