 ZOOK Metal Rupture Disks

 

URA Series Universal Reverse Acting Metal Rupture Disk

 

  • Single disk design covers 95% of plant requirements

  • Scoreless design offers higher cycle life when compared to scored reverse acting disks

  • Low and high burst pressures available in a single design

  • Excels in liquid or gas applications

  • 0% manufacturing range is standard

  • Operates to 90% of the disk's rated burst pressure

  • Non-fragmenting design

  • Excellent for isolating safety relief valves

  • Damage ratio of 1.0 or less

  • Resists product buildup.  Only the smooth side of the disk is exposed to the process medium

  • Additional TFE corrosion protection available (specify URA-L)

  • 3-dimensional tag

  • ASME UD stamping available

 

D Series Composite Forward Acting Metal Rupture Disk

  • Forward-acting, tension-loaded design, with laser cut metal cap, metal or TFE seal

  • Operates to 80% of the disk's marked burst pressure

  • Sizes 1/2" thru 24" diameters

  • Burst ratings range from 3 to 2,500 PSIG

  • Temperature ratings up to 900F (482C)

  • Suitable for liquid, gas, or 2-phase flow

  • 3-dimensional tag

  • UD stamping available

 

PB Series Forward Acting Metal Rupture Disk

  • Forward-acting, tension-loaded design without score lines

  • Standard 30 angle seat design

  • Burst ratings 5 to 50,000 PSIG

  • Operating pressures to 70% of the disk's marked burst pressure

  • Sizes 1/4" thru 24" diameters

  • Temperature ratings up to 900F (482C)

  • Suitable for liquid, gas, or 2-phase flow

  • 3-dimensional tag

  • UD stamping available

 

SFAZ Series Scored Forward Acting Metal Rupture Disk

  • Solid metal scored disk

  • Operating pressures to 85% of burst rating

  • Non-fragmenting design is suitable for liquid, gas, or 2-phase flow

  • Scored after disk material is formed to a high crown height.  Permits use of thicker material and allows lower ratings to withstand full vacuum

  • Burst ratings 30 to 1,800 PSIG

  • Sizes 1/2" thru 20" diameters

  • Temperature ratings up to 900F (482C)

  • Materials of construction:  316SS, Inconel, Monel, nickel, or aluminum
