Flow Fuses
Lee flow fuses are individually designed to meet custom requirements. The valve design functions as a normally open check valve. As the flow rate increases beyond a specified value across the valve, a poppet shuts against the valve seat and stops the flow. Valve materials are typically stainless steel but can be tailored to specific requirements. Lastly, our flow fuses are suitable for system pressures up to 15,000 psi.
Insert-style flow fuses are available in 0.187, 0.281, and 0.375 inch diameters with the fused flow direction available in forward and reverse. Cartridge-style flow fuses are available in 0.295, 0.483, 0.798, and 0.989 inch diameters. A zero leak version using an elastomeric seal is also available.

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.

Lee A.F.O.® (Axial Force Only) Plugs
Unlike other plugs in our product family, A.F.O. Plugs are both removable and reusable due to their threaded design, which allows technicians easy access to sealed passageways. In spite of this, the A.F.O. Plug still seals up to 56,000 psi. Each plug features a floating seal that self-aligns, allowing for threaded holes that aren’t concentric with the through-hole. Lastly, the A.F.O. designation means that no radial force is applied during installation, making this component suitable for thinner-walled housings. See Installation Process Specification P1013 (which applies to all A.F.O. Plugs) for more information.
A.F.O. Plugs are made from stainless steel and are available in standard diameters from 0.190 to 0.625 of an inch.

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.
