flat-seat holder

for reverse acting rupture disks for a leak-free seal.

The unique design of the IG-KUB^®-PTU rupture disc holder always guarantees the proper insertion, and enables the pre-assembly of the rupture disc. This avoids a damaging of the rupture disc, which can then be reused after dismantling, for example, within the scope of an inspection.

The sealing edge of the seat surface ensures a leak-free sealing through a fully-metallic clamping. The inside diameter of the rupture disc holder outlet performs a support function and guarantees the optimal opening behavior when the defined burst pressure is reached. The integrated pre-assembly bolts allow an easy and safe installation of the rupture disc. The holder can be used for a wide range of flanges and various pressure classes.

Advantages
