Selective Shuttle 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 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%.

Known for their durability, longevity, and small size, Lee bypass valves are designed to shunt flow across an actuator piston when the system pressure is either shut off or lost. They are normally open, with a hydraulically actuated pilot-to-close feature. These stainless steel valves are available in a 0.375 inch diameter insert for system pressures up to 4000 psi, have a maximum restriction of 70 Lohms when fully open, and weigh only 16 grams each. Similar to Lee shuttle valves, Lee bypass valves include a polyimide compression seal to ensure there is no external leakage across the three-port design when properly installed.
