The Reverse Acting Rupture Disc IKB® with Patented Manufacturing Process

The IKB® rupture disc was developed to provide reliable protection against excessive overpressure and vacuum in equipment such as pressure vessels, pipe systems, gas cylinders and reactors. It is suitable for applications with gas, steam and liquids* as well as for isolating safety valves. IKB® permits a standard operating ratio of up to 95%**.

The patented manufacturing process produces an instant, full and fragmentation-free opening across the full width of the vent. A high-quality rupture disc produced without the need for mechanical scoring or knife constructions. This ensures exceptionally high resistance even under cyclic loads. The extremely simple installation of a suitable rupture disc holder is torque independent and requires no special tools.

*If there is a gas cushion upstream of the rupture disc.

**Depending on the specific application.

  • Maximum safety even at high pressures.
  • You can use safety valves manufactured from lower cost materials because they do not encounter the medium during normal operation.
  • In-situ tests reduce safety valve maintenance costs.
