UNDERSTANDING TRUCK-MOUNTED HYDRAULIC SYSTEMS

Relief pressure is the pressure at which the system relief valve will open and bleed flow back to the reservoir until the system pressure diminishes. Typically, the relief pressure will be set approximately 15% above the system working pressure. Thus, a system designed to operate at 2,000 PSI would have its relief valve set for 2,300 PSI.
