Graphite Rupture Disks
Zook’s Graphite Rupture Disks are the global leader in high performance, economical, highly corrosive resistant and tamperproof graphite products.

Types of Disks Include:

Duplex: The DUPLEX Type Graphite Disk is the best choice for applications involving highly oxidizing agents and halogens.

FS-Inverted: ZOOK’s Fluoropolymer Sintered Graphite Rupture Disk (bursting disc) offers enhanced features when compared to resin impregnated graphite disks. The Fluoropolymer coating is sintered at a high temperature onto a graphite blank. The durable coating seals the graphite material enhancing the corrosive capability and allows the disk to operate at sub-zero to elevated temperatures with minimal effect on the burst performance of the rupture disk (bursting disc).

FS-V Inverted: ZOOK’s Fluoropolymer Sintered Graphite Rupture Disk (bursting disc) offers enhanced features when compared to resin impregnated graphite disks. The Fluoropolymer coating is sintered at a high temperature onto a graphite blank. The durable coating seals the graphite material enhancing the corrosive capability and allows the disk to operate at sub-zero to elevated temperatures with minimal effect on the burst performance of the rupture disk (bursting disc).

Insulated: The Insulated Unit Graphite Rupture Disk (bursting disc) is best for temperatures exceeding 430°F (221°C) to 700°F (371°C).

Inverted: The INVERTED Type Graphite Rupture Disk (bursting disc) is the best choice for higher burst ratings.

Mono: The MONO Type Graphite Rupture Disk (bursting disc) is the best choice for low and intermediate burst ratings.

RT2: The RT2 Type Graphite Rupture Disk (bursting disc) is a replacement element design.

RT2T: The RT2T Type Graphite Rupture Disk (bursting disc) is a replacement element design.

Two-Way: The TWO-WAY Type Graphite Disk is dual rated to protect against two different pressures in opposite directions.

ZAM Plus Rupture Disk Alarm Sensors

The ZAM Plus Rupture Disk Alarm Sensors have a surface mounted monitor designed to remotely detect the condition of a rupture disk (bursting disc) in service. Used in conjunction with the ZOOK ZENSOR®, BA, RDI, BI or similar devices, it will immediately warn the operator of a ruptured disk. The alarm system uses a normally closed electrical circuit. When the disk ruptures, it breaks the circuit, triggering the alarm. The ZOOK ZAM alarm system is capable of detecting a ruptured disk condition in applications involving highly electrically conductive fluids.

Rupture Disk Alarm Sensors Features:
- Intrinsically safe output for Class I, II, and III, Division 1, Groups A, B, C, D, E, F, and G hazardous locations
- Utilizes FM approved, PED and CSA compliant I.S. barrier
- Enclosure: NEMA Ty[e 12, constructed of 14 gauge steel with continuously welded seams and oil resistant seals
- Provides an audio/visual signal and an output relay for each channel; the channel will automatically reset once the burst indicating device is replaced or reset
- The audio alarm can be silenced with a push button switch
- Contains front panel push buttons for testing each channel; this function can also be performed remotely
- Field replaceable I.S. barrier module and power supply
