This assembly is called Type DSV rupture disk. This assembly is called a PLD rupture disk. A plastic liner covering and isolating a built-in support from process media becomes a PLDV rupture disk. In severe applications, metal exposure may not be desirable, hence the plastic covering. All standard disks with angular seating are listed on the following pages.
Listing is by sizes with a full selection of standard disks for each size.
Other metals available. The highly accurate disk is adaptable to standard threaded or bolted type tank car fittings. The pressure zone of the TC disk is the slotted top section. Teflon seal isolates top section from contents of the tank. The vacuum support prevents excessive downward movement of the seal should the disk be subjected to vacuum during unloading or while car is in transit.
