If a relief valve is fitted to a hydraulic power steering system?

If a relief valve is fitted to a hydraulic Power Steering system, it serves as a safety mechanism to prevent excessive pressure buildup within the system. When the pressure exceeds a predetermined limit, the relief valve opens, allowing fluid to escape and thereby protecting components from damage or failure. This ensures the system operates efficiently while maintaining safety and reliability. Additionally, it helps to prolong the lifespan of the hydraulic components by preventing stress and potential leaks.
