Introduction
Bursting disc is a complete arch shell, after instable flipping, it is cut for many pieces by buckling device knife to achieve pressure relief.
Characteristics
•Anti-fatigue, it can be used for a pulse pressure occasions.
•The highest working pressure can get to the 90% of the set burst pressure.
•It can withstand full vacuum state without bracket.
•Small fragment design can connect safety valve in series.
•Applicable to gas medium.
