High Pressure Burst Disc (15~25 PSI)

High Pressure Rupture Disc

A typical vacuum system is engineered to operate under external (atmospheric) pressure loads and not designed for internal pressurization. AGP sacrificial high pressure burst discs are important and preventative single-use safety devices designed to protect vacuum systems against accidental over-pressurization. For instance, a runaway chamber gas-backfill operation could lead to rapid internal pressurization of a vacuum vessel, possibly exceeding its internal load limits. Aside from protecting delicate system instruments and equipment like vacuum viewports — burst discs will also minimize risk of injury to system operators and/or other laboratory personnel. 

AGP High-pressure burst discs are designed to rupture when they encounter vacuum-to-atmosphere pressure differentials of between 15 to 25 psi. These high pressure rupture discs have unique stress-patterns scored onto their thin metal diaphragms, effectively pre-stressing them for precise rupture pressure control. AGP burst discs are designed with large deflection areas and are available/certified for two pressure ranges. High-pressure rupture disc models are designed to rupture between 15 and 25 psi. Caution, please note that ruptured burst discs cannot be repaired. Once compromised, they must be replaced to make the vacuum system operational again.
