Forward Acting, Multi-Layer Bursting Disc

	BT-STAR-HL with star-shaped opening

These forward acting Bursting discs are suitable for a wide range of low to high pressures. The triple section design minimises the risk of fragmentation, at all pressures, with its star shaped opening formation.

To achieve lowest possible tolerances the breaking points are introduced utilising state- ofthe- art laser production technology. An integral vacuum support guarantees full vacuum resistance irrespective of disc Size, up to DN 600 (24").

The burst element is downstream (venting side) of the process, away from any corrosive media, thereby providing problem free production in corrosive media processes.  Operating Ratio of the BT-STAR Disc is 80% of the burst rating.

In applications below 1 barg the BT-STAR Disc can be installed directly between companion flanges, without a companion holder.

For medium to high burst ratings the entire assembly, including the sealing membrane is constructed of stainless teel. When used with a flat seat IG-HL Burst disc holder the assembly provide absolute leak-tight integrity.
