What is the purpose of the pressure relief valve?

It serves to release abnormally high pressures before they damage a system. For example, a water heater contains a pressure relief valve. If a thermostat malfunctions, the heater would continue to heat, turning water to steam. The higher pressure created by that would cause the water heater to explode- but the pressure relief valve reacts to the higher pressure, and vents it off safely.
