PRODUCT DATA SHEET The Lee Company's Industrial MicroHydraulics Group (IMH) introduces the newest addition to our line of miniature, poppet-style Pressure Relief Valves with the release of a forward flow 5.5 mm model. Our line of poppet-style valves provides faster opening ■ Fast Opening Rate - Stable Flow - Quiet Operation - Minimizes System Stress ■ 100% Tested - Improves System Level Yield Rates ■ Small Size - Saves Space and Weight rates and more stable flows than typical ball style relief valves. Measuring just 5.5mm in diameter and 16.8 mm long, the new valve weighs only 1.8 grams. This new model gives the system designer additional flex- ■ All Stainless Steel Construction - Compatible With Most Fluids ■ Low Hysteresis - Improves System Performance 5.5 mm RELIEF VALVE FORWARD FLOW ibility to optimize their system layout. Simple to install, the new Relief Valve uses Lee's field-proven insert principle that provides secure retention and eliminates the need for threads, o-rings or in-house designs. To install, simply insert the relief valve into a drilled installation hole and drive the CHECK DIRECTION INSTALLATION HOLE RELIEF FLOW DIRECTION expansion pin flush to seal and lock the valve in place. Designed for reliable operation, the new Relief Valve features robust, all stainless steel construction and 100% performance testing to ensure consistent, long term performance. 0“otSJ8 The new Relief Valve s compact size, super- *LOA before installation.

Drive the The installation tool can bottom on the insert body with no con- expander pin flush to within 0.25 mm (0.010") above flush of the sequence. Lee Installation Tool part number CCRT0900120S is relief valve body. Use a maximum installation force of 625 KgF available. (1,380 lbs. force). LOHM 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...
