Pressure relief and pressure activation are distinct safety mechanisms in rupture disk applications.
Pressure relief is a passive measure that prevents overpressure by rupturing at a predetermined threshold, allowing excess pressure to vent safely. It operates automatically, requiring no external intervention.
In contrast, pressure activation is an active response to pressure changes, often used to control processes or trigger actions like valve operation. While pressure relief prevents catastrophic failures, pressure activation manages pressure-related functions, making both crucial for system safety.
