Over pressure Burst Discs
Over Pressure Burst Discs are designed as a safety device to help protect vacuum systems against accidental over pressure. This can occur when internal gas or cryogenic liquid lines fail causing a rapid over pressure which could break view ports or damage delicate test equipment.
Over pressure causes the thin foil diaphragm to come into contact with the ten sharp edges of the housing and ruptures the foil diaphragm. This relieves the pressure in the system. Once the foil diaphragm has been ruptured, the unit must be replaced.
The disc is designed to burst with an over pressure of either 25psig or between 7.5-11.5psig.
Pressure relief valves are also available, see Valve section of this website.
