PRECISION MICROHYDRAULICS PRODUCT DATA SHEET The Lee Company’s new 687 Side Exit Flosert is the latest addition to Lee’s line of miniature flow regulating valves. These valves are pressure compensated to provide a constant flow over a wide range of pressure differentials. This new valve is ideal for high pressure hydraulic applications with system pressures up to 5000 psi. Nominal weight is just 48 grams. ■ Regulated Flow Rates Available from 1.5 to 5.0 GPM ■ Designed for System Pressures up to 5000 psi ■ Regulated Flow Tolerance: +/- 10% ■ Weighs only 48 grams ■ 100% Tested and Inspected ■ Endurance Tested to 100,000 Cycles Minimum The 687 Side Exit Flosert is constructed entirely of stainless steel for durability and long life. Regulated flow rates are available from 1.5 to 5.0 GPM. Each Flosert is 100% tested and inspected to ensure reliable, consistent performance. Regulated Flow Tolerance: +/-10% Nominal System Pressure: up to 5000 psi Nominal Weight: 48 grams Finish: All CRES Parts Passivated.

LOHMS LAWS (liquids) Every engineer will be interested in our simple system of defining the fluid resistance of Lee hydraulic components. Just as the OHM is used in the electrical industry, we find that we can use a liquid OHM or "Lohm" to good advantage on all hydraulic computations. When using the Lohm system, you can forget about coefficients of discharge and dimensional tolerances on drilled holes. These factors are automatically compensated for in the Lohm calculations, and confirmed by testing each component to establish flow tolerances. The resistance to flow of any fluid control component...
