At what pressure is the relief valve set to discharge or by-pass?

• A. 100% of the working pressure
• B. 110% of the working pressure
• C. 125% of the working pressure
• D. 150% of the working pressure

Answer: (C)

The relief valve is typically set to discharge or by-pass at 125% of the working pressure. This is a safety measure designed to protect the hydraulic system from excessive pressure, which can lead to equipment failure or catastrophic incidents. By setting the relief valve to this percentage, it ensures that the system can handle normal operating pressures while also providing a safeguard against pressure surges. If the pressure reaches this threshold, the valve opens to release excess fluid, thus preventing potential damage to the system. This specific setting of 125% aligns with industry standards and regulations regarding hydraulic systems, ensuring optimal safety and functionality in elevator operations. Understanding this configuration is crucial for maintaining compliance with safety standards and ensuring the reliability of elevator systems.
