NACE COMPLIANT HIGH PRESSURE LEE CHEKS® - 1

product data sheetnace compliant high pressure lee chek® The Lee Company’s new NACE Compliant High Pressure Lee Chek® Valves are specifically designed for the harsh duty applications found in the oil tool industry. They are constructed entirely of corrosion-resistant materials that comply with NACE specification MR0175/ISO 15156. These new check valves feature a durable MP35N poppet and seat, and are designed for checked direction pressures up to 15,000 psid. ■ All Valve Materials Compliant with NACE MR0175/ISO 15156 ■ 15,000 psid Maximum Working Pressure ■ 5 Standard Sizes, as Small as 0.125" Diameter ■ Free Flow Lohm Rates from 400 Down to 15 Lohms ■ 100% Tested and Inspected pin insert The new valves are available in free flow forward and free flow reverse directions, with cracking pressures of 5 ± 3 and 1 ± 0.5 psid. Sizes range from 0.125” to 0.500” in diameter, with free flow Lohm+ rates from 400 to 15 Lohms. Each NACE Compliant High Pressure Lee Chek® valve is 100% tested and inspected to ensure reliable, consistent performance, eliminating the need for additional in-house testing. Pins are prewaxed. Do not degrease. Do not lubricate. t The Lohm is a measure of flow resistance. Additional information can be found on the reverse side and at www.TheLeeCo.com. * These forward flow check valve models require secondary retention for check direction pressure above 8,000 PSID.

NACE COMPLIANT HIGH PRESSURE LEE CHEKS® - 2

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...
