The Zook PB Bursting Disc mounts with the concave surface facing the process media. As pressure increases above the recommended operating pressure, the disc will bulge until it reaches the maximum tensile strength of the material and ruptures.
Zook PB Bursting Disc – Forward Acting
- Operating pressures to 70% of the disc’s marked burst pressure
- Seat Configuration: Angular 30°
- Sizes 1/4″ thru 24″ diameters
- Temperature ratings to 900°F (482°C)
Options:
Vacuum Supports are required for vacuum services. Vacuum supports are attached to the process side of the disc and allow the disc to support a full system vacuum.
Liners / Coatings Teflon liners are available to provide protection from corrosive media if required. Coatings are also available. Refer to (Table 1 in Spec Sheet) for maximum temperature ratings for disc, liner and coatings.
Protective Rings can be used with Zook PB Bursting Disc to provide stability and protection when thin materials and/or liners are used.
