What is the purpose of pressure relief valves in a diving system?

The purpose of pressure relief valves in a diving system is to provide safety against over pressurization. These valves are critical safety devices designed to prevent potential hazards that could occur if the pressure within a system exceeds safe limits. In a diving environment, where equipment is subjected to varying pressures, a pressure relief valve acts as a failsafe mechanism. If the pressure inside a tank or system rises beyond acceptable levels, the valve automatically opens to release excess pressure, thereby reducing the risk of equipment failure, leaks, or catastrophic incidents such as explosions.

By ensuring that pressures remain within safe thresholds, pressure relief valves contribute significantly to the overall safety and reliability of diving operations. Maintaining appropriate pressure levels is essential for both the functionality of diving equipment and the safety of divers, as excessive pressure can cause serious injuries or damage.
