What is the function of a pressure relief valve?

• A. To regulate flow rate
• B. To prevent pressure build-up
• C. To control temperature
• D. To monitor product levels

Answer: (B)

The function of a pressure relief valve is primarily to prevent pressure build-up in systems that contain gases or liquids. This is crucial because excessive pressure can lead to equipment failure, leaks, or even catastrophic explosions. The pressure relief valve automatically opens when the pressure reaches a specified set point, allowing fluid or gas to escape, thereby maintaining a safe operating pressure within the system. In many applications, such as in pipelines, storage tanks, or chemical processing facilities, the ability to manage pressure is essential for safety and operational integrity. By effectively venting excess pressure, the pressure relief valve serves as a critical safety device that helps to ensure the reliability and functionality of the entire system. The other options relate to functions that do not pertain to the role of a pressure relief valve. Flow rate regulation, temperature control, and monitoring product levels involve different types of devices and systems. Each serves a different purpose specific to the operational needs of a petroleum supply system.
