Lee A.F.O.® (Axial Force Only) Plugs

This valve configuration is typically used to select between the main hydraulic system and the emergency backup that’s biased in the normally closed port. Its non-interflow design means that its three ports are never open simultaneously. These valves can also be used to extend a large unequal area actuator, where reduced actuation force may be permissible in one direction. Lee spring-biased shuttle valves are available in sizes from 0.187 to 0.500 of an inch.

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%.

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.
