Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to "vent" the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.

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.

Schematic diagram of simple relief valve is shown in Fig. 1.1 and three-dimensional view is shown in Fig. 1.2. It is normally a closed valve whose function is to limit the pressure to a specified maximum value by diverting pump flow back to the tank. A poppet is held seated inside the valve by a heavy spring.
