rupture disc STAR - For low to high pressures
STAR is a three-section solution primarily used in applications with low to high response pressures, especially in the oil and gas industry, petrochemicals and chemicals, applications with liquified gases and processes that involve pressure cycling. The standard operating ratio is up to 80 %* of the minimum response pressure. Extremely tight tolerances of +/- 5 % are possible. For applications with a burst pressure of less than 1 barg, STAR can be installed directly between flanges.
* Depending on the specific application
The advanced manufacturing process guarantees minimum fragmentation when opening even at the highest pressures. Its star-shaped opening pattern is flatter than that of other rupture discs so it requires less installation height. The integrated vacuum support guarantees high vacuum resistance.
Your advantages
- Minimal space required due to starshaped opening pattern.
- Cost-effective as different materials can be used for the individual elements of the rupture disc.
- Minimum risk of fragmentation even at high pressures.
- Also suitable for isolating safety valves.
