The P/V breaker in the inert gas system is primarily associated with preventing which condition?

A P/V breaker acts to keep the inert gas system’s pressure within safe bounds, preventing both overpressure and underpressure. In an inerting setup, maintaining a slight positive pressure helps keep air and moisture out of the space being inerted. If pressure rises too high, the breaker vents excess gas to prevent vessel or piping damage. If pressure drops too low, it allows gas to enter or release to prevent a vacuum from forming, which could pull in contaminants. That dual protection against pressure deviations is what makes it primarily associated with preventing over- and under-pressure. Backflow is typically managed by valves, temperature control by cooling, and leakage by seals and integrity checks, so they aren’t what the P/V breaker is designed to handle.
