Continental Disc Corporation is committed to providing the products, services, and quality you expect from the leading overpressure safety company.

CAL-VAC® Rupture Disc

Characteristics: is a double acting rupture disc (bursting disc) which will relieve an ultra low (inches of water column) vacuum pressure or a position pressure condition. The CAL-VAC® Rupture Disc (Bursting Disc) has a flat seat design to reduce susceptibility to product buildup and promote easier cleaning to meet FDA requirements.
Dimensions: 3“ – 12“ (80 mm – 300 mm)
Burst pressure:  Positive: 2 – 150 psig (0,138 – 10,3 barg)
Vacuum: 1 – 30 INWC (2,5 – 75 mbar) 
Max. temperature: 400°F (204°C)
Operating ratio:  Positive: 80%
Vacuum: 90% of min. burst pressure or within 15 mbar (whatever is higher)
Material: stainless steel 316, 316L, HASTELLOY®C, Nickel, MONEL®, INCONEL®, Tantalum, TEFLON®
Media: liquid or gas
