Pressure Burst Disk Low Pressure Version
Allectra has introduced a low pressure version of the standard Pressure Burst Disk. The Allectra Pressure Burst Disks are designed to rupture and release gas in the event of potentially hazardous pressures greater than atmospheric pressure occurring in the Vacuum System.
The Standard type: membrane ruptures at system pressure of max. 1.7 bar overpressure
Low Pressure type: membrane ruptures at system pressure of max. 0.8 bar overpressure (ASME-UD certified)
Some features of the Pressure Burst Disk as follows:
-UHV compatible, high bakeable to 350°C and leak tight to <5x10-10 mbar l/s
-It is ESSENTIAL FOR ALL SYSTEMS WITH LN / LHe COOLING
-Optional gas recovery system to prevent gases escaping into the atmosphere
-DN40CF and DN16CF versions / KF types and custom flanges
Allectra has also released an Ultra Low Pressure Burst Disk with a rupture pressure below 0.5 bar on a 63CF or ISO63 flange.
With this component, the overpressure regulations do not apply to the system.
