Lee A.F.O.® (Axial Force Only) Plugs

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 HI-BAR Inlet Safety Screens save space and weight by incorporating the inlet screen directly into the boss fitting end rather than the more traditional approach of having the inlet screen installed in the manifold directly below the fitting. This unique design also offers greater flow and dirt holding capacity than a design that completely encapsulates the screen in the fitting. Lee HI-BAR Inlet Safety Screens are machined entirely from 15-5PH stainless steel and are rugged enough to withstand pressure differentials up to 6000 psi without burst or collapse. Each component is 100% proof pressure tested before shipment to ensure reliable performance. These screens are available in -4, -6, -8, and -10 configurations (AS33514 flareless tube to AS930 port fitting ends), which can be installed into a standard boss per AS33649 or equivalent. Eight standard hole sizes ranging from 50 to 500 micron are available.

Safety relief valves are designed to be fast-acting components that protect systems with the potential for sudden pressure spikes. These valves may sit dormant for indeterminate amounts of time before needing to be used, so it’s crucial that they always work as intended. Our safety relief valves are available in low-leak and tight hysteresis configurations. To ensure reliable operation, we 100% test each component for crack, flow point and reseat pressure.

Our safety relief valves are available in 0.187, 0.250, 0.281 and 0.375 inch insert diameters and 0.687 inch threaded configurations. They are constructed entirely of stainless steel and are available screened and unscreened. Built-in damping ensures quiet operation. Cracking pressures ranging from 20 to 5900 psid.
