What is the role of a pressure relief valve?

The role of a pressure relief valve is to protect a system from excessive pressure build-up. This is a critical safety feature in many mechanical and fluid systems. When pressure inside a vessel or system exceeds predetermined limits, the valve opens to allow excess pressure to escape, thereby preventing potential system failure or explosions that could occur if the pressure continues to rise unchecked.

The pressure relief valve functions by automatically responding to pressure changes, ensuring that the pressure remains within safe operational limits. This proactive measure not only safeguards the equipment but also enhances overall safety, protecting personnel and the environment from the dangers associated with high-pressure scenarios.
