The RT2 disk is suitable for gas, liquid or vapour service
Available in nominal sizes from 1” (25 mm) thru 12” (300 mm)
Fits into a re-usable disk holder
The ZOOK RT2 type Graphite bursting disk is equivalent to most other manufacturers replacement element type graphite disks, i.e. EHG2, G2, Series 2, E2, and in most cases will fit into their holders (Consult ZOOK first)
The RT2 disk can handle an operating pressure of up to 90% of the minimum rated burst pressure of the disk
Standard burst tolerances are +/- 10% for 5 psig (0.34 barg) and above, and +/- 0.75 psig (0.05 barg) for below 5 psig (0.34 barg)
The RT2 disk can withstand full vacuum if rated at 25 psig (1.72 barg) and above. For disks rated below 25 psig (1.72 barg), a reverse pressure support (RPS) must be fitted into the disk holder. (Note: The RPS is a fixed type vacuum support and will reduce the free flow area of the disk on burst)
For additional corrosion resistance and wider temperature range special fluoropolymer sintered RT2T disk is available. (Minimum pressure may vary)
Burst detection available for most applications by fitting RDI detector in place of holder outlet side gasket
The RT2 disks will be manufactured, where applicable, in accordance to the latest pressure equipment directive (PED) 2014/68/EU (Category IV) and EN-ISO-4126-2 and are CE Marked. Burst test certificates will be supplied with the disks (Third party witness testing is also available if required)
Standard holder materials available: Graphite, Stainless Steel and FS (fluoropolymer coated stainless steel)
