Tension-loaded bursting disc type SFAZ
Description
-SALES ONLY IN GERMANY-
The SFAZ rupture disc from ZOOK is an all-metal, tension-loaded rupture disc for demanding applications. The bursting disc is not notched until after the cambering process, resulting in a load capacity of up to 90% of the minimum bursting pressure, which is outstanding for conventional bursting discs. It opens fragment-free along the cross-shaped pre-notch when the response pressure is reached.
