PRODUCT DATA SHEET Hl-Q PRESSURE RELIEF VALVE Relief Valve is designed for applications that require both a high relief pressure and a high flow rate in a compact package. This new relief valve is capable of relief pressures up to 5400 psid and flow rates over 19 GPM. The valve utilizes aside inlet flow path to help minimize the installation boss size and weight. The Hi-Q Pressure Relief Valve is offered in a range of cracking pressures from 1000 to 5400 psid. It is designed for nominal tem peak pressures up to 6750 psi. Each Lee Pressure Relief Valve is 100% tested and inspected to ensure reliable, consistent Recommended Valve Lift:...600 Lohms Nominal System Pressure:.. up to 5000 psi Non-Relief Direction Capable of Flow Rates Over Designed for System Pressures Endurance Tested in Excess of 0-RING WITH ONE BACKUP RING See reverse side for installation hole.

Additional information can be found on the reverse side and at www. TheLeeCo.com. NOTE: Pressures in excess of 500 psid in the non-relief flow direction may cause damage to the valve's critical sealing surfaces.

INSTALLATION HOLE LOHMS LAWS (liquids) Engineers 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 hydraulic 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 of any fluid control component...
