What is the function of a pressure relief valve?

The function of a pressure relief valve is to release excess pressure from a system to prevent damage. This safety device is crucial in various systems where pressure can build up to dangerous levels, such as in boilers, pipelines, and other pressurized environments. By opening when pressure exceeds a set limit, the valve allows for the safe release of steam or fluid, thereby protecting equipment and maintaining system integrity.

Utilizing a pressure relief valve helps to prevent potential catastrophic failures, like explosions or ruptured pipes, which can occur if the pressure is not adequately controlled. Therefore, the key role of this valve is to act as a safeguard, ensuring the safety and functionality of the entire system under varying operational conditions.
