Alternative reverse buckling devices

Standard features:

  • Operating pressure to 90% of the marked burst pressure
  • Designed for gas, liquid or multi-phase flow conditions
  • Lowest burst pressure in a reverse buckling style disk
  • Optimum fatigue resistance in pressure pulsating or cycling conditions
  • Designed for non-fragmentation
  • Ideal for relief valve or tank vent isolation

Product Offerings

Innovative frustum design disk providing overpressure relief at low pressure; the circular score line has an interrupted ‘hinge’ segment which retains the disk’s central petal and prevents fragmentation.
Eco-Saf® ECR™
Eco-Saf® ECR
Offers the lowest burst pressures available from a reverse buckling disk; The disk relieves overpressure or vacuum by reversing and opening at the perimeter of the dome
Sure-Saf® CSI™
Sure-Saf® CSI ECR
Uses SAF technology (structural apex forming), which enhances accuracy of burst pressure
Provides overpressure protection by reversing and snapping against precision stainless steel knife blades
A single-use rupture disk assembly (no holder required) for isolating safety relief valves; For retrofit with fixed piping
An all purpose SKR rupture disk partnered with a threaded union-type holder
