PRECISION MICROHYDRAULICS PRODUCT DATA SHEET 250 INVERSE LEE VALVE The Lee Company’s new 250 Inverse Shuttle Valve is the latest addition to Lee’s line of miniature inverse shuttle valves. The poppets in this shuttle valve are designed to allow the lower inlet pressure to flow while the higher inlet pressure is blocked. This new shuttle valve is ideal for high pressure applications with system pressures up to 5000 PSI. The metal components are constructed entirely of stainless steel for durability and long life. Each Inverse Shuttle Valve is 100% tested and inspected to ensure reliable, consistent performance. SHUTTLE™ ■ Designed for system pressures up to 5000 psi ■ Weighs only 8 grams ■ All metal components made from stainless steel ■ 100% tested and inspected ■ Endurance tested to 250,000 cycles INSTALLATION HOLE PERFORMANCE Unbalanced Flow: (290 Lohms maximum) Port A to Port C (Port B Closed): 0.31 GPM min. @ 25 psid (PB > 1.25 x PA) Port B to Port C (Port A Closed): 0.31 GPM min. @ 25 psid (PA > 1.25 x PB) Anti-Cavitation Flow: (260 Lohms maximum) Port C to Port A: 0.35 GPM min. @ 25 psid Port C to Port B: 0.35 GPM min. @ 25 psid Maximum Leakage: Port A to Ports C & B (Ports C & B at atmosphere): 5 drops/minute at 50 psid Port B to Ports C & A (Ports C & A at atmosphere): 5 drops/minute at 50 psid Nominal System Pressure: up to 5000 psi Nominal Weight: 8 grams Valve performance on MIL-PRF-83282 at 85 °F 1 drop = 50 uL The Lee Company • 2 Pettipaug Road, PO Box 424, Westbrook, Connecticut 06498-0424 Tel: 860-399-6281 • Fax: 860-399-7037 • inquiry@theleeco.com • www.theleeco.c

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...
