The primary purpose of a pressure relief valve in a hydraulic system is to protect the system from overpressure. Overpressure can occur due to various reasons, such as a sudden load increase, a malfunctioning control valve, or thermal expansion of the hydraulic fluid. The pressure relief valve functions by providing an alternate path for the hydraulic fluid to flow back to the reservoir when the system pressure exceeds a pre-set limit. The valve is typically spring-loaded, and the spring tension determines the pressure at which the valve will open. When the system pressure re....
