THE VAC-SAF DISK COMPONENTS VAC-SAF™ rupture disks consist of three main parts: 1 A perforated and slotted metal 2 A fluoropolymer seal with integral fluoropolymer button. 3 A fluoropolymer slit cover be- tween the fluoropolymer seal and the metal section prevents damage to the seal by the slits in The VAC-SAF™ System rupture disks can be utilised in various ways: Type DKB™. For vacuum and overpressure relief in a KB-7R™ Safety Head, for installation between standard pipe flanges. Type VKB™. For vacuum and overpressure relief in a KB-C™ Safety Head with sanitary/ hygienic fittings. Type...
