A Pressure Relief Valve operates by monitoring system pressure continuously, opening to release fluid to another circuit (usually a return tank) once the pressure surpasses a specified setting. This action prevents excess pressure buildup on the inlet side, thus maintaining safe pressure levels in the system. When the system pressure falls below the set limit, the valve closes automatically, resuming normal pressure control. This cycle protects hydraulic components from potential damage due to high pressure.Attributes:• Prevents over-pressurization that can damage components.• Opens at predetermined pressure thresholds.• Automatically resets once the pressure drops to a safe level. • Allows for controlled fluid flow to reduce excess pressure.Applications: A Pressure Relief Valve is used in hydraulic circuits of equipment, located on the inlet side of the system to monitor and regulate internal pressure.
