What is a common safety device used in hydraulic systems?

A pressure relief valve is a critical safety device commonly used in hydraulic systems. Its primary function is to protect the system from excessive pressure that could lead to equipment failure or catastrophic leaks. By allowing fluid to escape from the system when pressures exceed a predetermined limit, the pressure relief valve helps to maintain safe operating conditions and prevents damage to hydraulic components.

In the context of hydraulic systems, maintaining the right pressure is crucial for effective operation. If the pressure becomes too high, it can compromise the integrity of hoses, fittings, and other components, potentially leading to dangerous situations. The pressure relief valve acts as a safeguard, triggering when the pressure threshold is reached, thus ensuring the safety and longevity of the hydraulic equipment.

While flow meters, hydraulic accumulators, and check valves are essential components within hydraulic systems, they do not serve the primary function of protecting against over-pressurization. Flow meters measure the flow rate of fluid, hydraulic accumulators store energy and smooth out pressure fluctuations, and check valves prevent backflow in the system. However, these devices do not provide the same direct safety function against excessive pressure that a pressure relief valve does.
