What is the function of a pressure relief valve?

The function of a pressure relief valve is to release excess pressure safely. This essential safety component is designed to maintain pressure within a system at a safe level, thereby preventing potential overpressure scenarios that could lead to equipment failure, leaks, or even catastrophic explosions. When the pressure within a boiler or another system exceeds a preset limit, the valve opens automatically, allowing the excess pressure to escape, typically in the form of steam or fluid. This mechanism effectively protects the system and ensures operational safety.

The importance of a pressure relief valve cannot be overstated, as it is a critical safety feature in high-pressure environments, such as boilers. Proper functioning of this valve helps maintain the integrity of the system under varying operational conditions.
