The advanced manufacturing process of the rupture disc STAR 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.
STAR is a three-section rupture disc 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 (Depending on the specific application). Extremely tight tolerances ( +/- 5 %) are possible. For applications with a burst pressure of less than 1 barg, STAR can be installed directly between flanges.
