Forward Acting Tension Loaded Disks Tension Loaded Solid Metal Rupture Disks Type DTM Series Disk Types Type D rupture disks consist of a slotted metal top section and either a metal or fluorocarbon seal. Pressure is applied to the concave side, subjecting the disk to tension loading. When vacuum is involved in any amount, a vacuum support is required. Adding a ring to the outlet side aids handling and installation, and is a type DRV disk. Ring material is nickel, aluminum, Monel® or 316ss. At low burst pressures a type DR rupture disk is recommnded to aid handling and installation ring material...
