What is the function of a pressure relief valve?

The function of a pressure relief valve is to prevent excessive pressure buildup in a piping system. This is crucial for maintaining safety and protecting equipment from potential damage or failure due to overpressure. When the pressure within a system exceeds a predetermined limit, the pressure relief valve opens, allowing fluid to escape and thereby releasing pressure. This action helps to avert possible hazards, such as ruptures or explosions, which can occur if the pressure continues to rise unchecked.

Understanding the specific function of a pressure relief valve underscores its importance in various applications, such as boilers, tanks, and various industrial systems. By ensuring that pressure does not exceed safe levels, these valves play a vital role in the overall integrity and safety of piping systems.
