Low Pressure Rupture Disk Overpressure protection for atmospheric vessels BS&B’s type AVTM disk is a low pressure rupture disk designed for direct ange installation. Features • Sizes 1-48 inches (25-1,200mm) • Gaskets attached on both sides • Low burst pressures: 0.25-40 psi (0.02-2.76bar) • Damage safety ratio < 1 • Manufacturing design range 0, -5%, -10% (Not available in all burst pressures.) • Operates up to 60% of minimum burst pressure • Vacuum resistant to 35% of minimum burst pressure. For greater vacuum resistance use model AVV with integral nonopening vacuum support (60% net opening area) Burst Pressure Capability Nominal size Standard materials Gaskets Compressed fiber, glass filled PTFE, others upon request Stainless steel (standard) Nickel Monel® Inconel® Hastelloy® C276 Tantalum Stainless steel barg Nominal burst pressure Burst tolerance Hastelloy is a trademark of Haynes International Inc.
