pressure relief valves

Pressure relief valves are safety devices used in systems involving liquids or gases, such as boilers, tanks, and pipelines. Their primary function is to automatically release excess pressure when it exceeds safe levels, preventing potential damage or explosions. When pressure builds up beyond the valve’s set point, the valve opens to let some fluid escape, then closes once normal pressure is restored. This ensures system safety and integrity, maintaining operational stability by preventing dangerous over-pressurization.
