PRECISION MICROHYDRAULICS PRODUCT DATA SHEET LEE VILA The Lee VILA is an economical, multiorifice restrictor designed to offer a range of metered Lohm* rates for high flow applications. Rated for working pressures up to 1500 psi differential, the VILA is constructed entirely from 2024-T4 aluminum, resulting in a robust design that is lightweight and corrosion resistant. The VILA’s unique metering element includes many orifices in series to help lower fluid velocities and reduce the possibility of cavitation. This multi-orifice design also offers up to a 90% increase in minimum passage size over a comparable single orifice restrictor, and therefore a higher tolerance to contamination. With bidirectional flow capability, the Lee VILA is available in 5 different Lohm Rates, ranging from 1600 to 4100 Lohms. In addition, each VILA is 100% tested for accurate and consistent performance. Contact your Lee Sales Engineer for information and technical assistance. ■ Lightweight 2024-T4 Aluminum Design ■ Excellent Corrosion Resistance ■ Lohm Rate Tolerance: ± 10% ■ 100% Tested Bi-directional Flow ■ Maximum Working Pressure: 1500 psid * The Lohm is a measure of flow resistance. Example: One Lohm will permit a flow of 100 GPM of water at 25 psid at 80°F. Additional information can be found on the back of this sheet or at www.theleeco.com.

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...
