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
FRS
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™
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™ ECR™
Uses SAF technology (structural apex forming), which enhances accuracy of burst pressure
RB-90™
Provides overpressure protection by reversing and snapping against precision stainless steel knife blades
SVI™
A single-use rupture disk assembly (no holder required) for isolating safety relief valves; For retrofit with fixed piping
SKR-U™
An all purpose SKR rupture disk partnered with a threaded union-type holderFor more details and comparison: Download RDD Quick reference guide
