PRODUCT DATA SHEET Chek® is an ultra miniature, precision, side-exit check valve. This 0.093" diameter check valve is based on the same field-proven technology as the 0.187" diameter side exit Lee Chek®. Weighing only 0.14 grams nominal, the 093 Lee Chek offers a 90% reduc- tion in weight over the 187 version and is 50% shorter, resulting in a corre- sponding reduction in installation boss Available in a forward flow configura- tion, the new Lee Chek is constructed entirely of stainless steel, and features a hard, metal to metal seat for dura- bility and long life. Each Lee Chek is 100% tested and inspected to ensure reliable, consistent performance. FREE FLOW FORWARD Finish: All CRES Parts Passivateci. Pins are prewaxed. Do not degrease. NOTE: Customer to provide adequate filtration Ultra miniature: Weighs only 0.14 grams INSTALLATION HOLE* *See reverse side for axial installation hole. The Lohm is a measure of flow resistance.

AXIAL INSTALLATION HOLE 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 calcula- tions, and confirmed by testing each component to establish flow tolerances. The resistance to flow...
