Safety components available online

December 2019: Allectra safety components are available online.

A pressure burst disc, also known as a rupture disc or bursting disc is a non-reclosing pressure safety device that, in most uses, protects a pressure vessel, equipment or system from over-pressurization or potentially damaging vacuum conditions.

Allectra Pressure Burst Discs are designed to rupture and release gas in the event of potentially hazardous pressures greater than atmospheric pressure occurring in the vacuum system.

We offer three versions with various flange sizes:

DN16KF Pressure Burst DiscStandard type: membrane ruptures at system pressure of max. 1.7 bar overpressure.

DN40CF Pressure Burst DiscLow Pressure type: membrane ruptures at system pressure of max. 0.8 bar overpressure.

Pressure Burst Disc, Ultra Low PressureUltra low pressure type: membrane ruptures below 0.5 bar and so this system does not fall under overpressure regulations. It has a mesh cover to prevent accidental damage to the membrane.



  • UHV compatible, high bakeable to 350°C and leak tight to <5 x 10-10 mbar l/s.
  • Protects sensitive components against accidental over-pressure in the vacuum system.
  • Optional gas recovery system to prevent gases escaping into the atmosphere.

DN40CF and DN16CF versions / KF types and custom flanges. ULP version needs 63CF or ISO63 flange
