Flosert Flow Regulators
For advanced applications, aircraft and defense manufacturers may wish to consider Lee Floserts. This is a pressure compensated flow control − in other words, the flow will remain constant across a wide range of differential pressures. A variable metering orifice automatically adjusts by sensing the flow rate in terms of differential pressure across a fixed orifice. Floserts are available with the Lee locking end for installation in diameters from 0.250 to 0.500 of an inch as well as a 0.687 inch threaded configuration. Also available are metered flow rates from 0.01 GPM up to 5 GPM, as well as high-pressure versions for operating pressures up to 5000 psi.

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.

Safety Relief Valves
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.

Lee JELA® Lubrication Jets
Lee JELA® Lubrication Jets generate a straight, well-defined stream of fluid to a predetermined target with differential pressures of 10 to 200 psid. Lee JELA® Lubrication Jets are 100% tested for capture efficiency, guaranteeing that over 90% of flow will hit a predetermined target 2 inches away. These units are ideal for directing streams of lubricating oil at critical bearings or cooling oil at meshing gears, or fuel at the inside of vaporizing tubes in aircraft combustion chambers. Lubrication jets are available in four sizes from 0.125 to 0.343 of an inch with Lohm rates ranging from 200 to 7500 with a +/-15% tolerance. The 0.187 inch size is available with an integral safety screen and Lohm rate tolerance of +/-10%.
