■ Suitable to mid and low pressure
■ Possible to manufacture it with very fine gauge of setting pressure
■ Strong resistance to corrosion by the material used in sealing sheet
■ Restricted temperature range due to the material used in sealing sheet
■ 5-folds or more multiple structure with regular rupture part
