Aug 14, 2007 Suited for process plants requiring optimal operating pressure in gas or liquid service, SIGMA EXL(TM) and SIGMA(TM) Reverse Buckling Rupture Disks feature SAF(TM) Technology to accommodate range of burst pressures. Design minimizes fatigue on rupture disk, optimizing plant uptime. Pre-torqued SRB-7RS Safety Holder allows disk to be removed and inspected without having to re-torque, while circular score causes rupture disk to burst without fragmentation.

May 07, 2007 Lift-Gard provides venting and rupture notification to guard against damage caused by explosions in bucket elevators transporting powder and bulk solids. Made of stainless steel, flat venting system combines integral frame and Flo-Tel(TM) detection device in one unit. If Flo-Tel(TM) detects initial explosion inside elevator shaft, it automatically switches off elevator motors to reduce risk of further explosion and stop elevator operation with open explosion vents.

Feb 22, 2007 Available in 316 SS, nickel, Inconel, and Monel, forward-acting, 24 in. FAS Disk is non-fragmenting, keeping disk pieces from entering piping system in event of disk burst. Unit can withstand full vacuum and will operate at up to 90% of stamped rating. Scored portion of disk is placed away from process, preventing product buildup and making it suited for sanitary applications. Non-torque sensitive design eliminates need for pre-torqued rupture disk holders.

Apr 11, 2005 Offered in sizes from 1–4 in., Model S-PRO-S combines bursting disk and sensor into single assembly with range of burst pressures from 16–150 psig. When disk bursts, sensor’s circuit is broken, triggering activation of alarm. Placement of sensor and disk scoring on vent side present smooth surface to process, minimizing product build up. Non-fragmenting design prevents contamination from rupture disk pieces entering process after bursting.

Dec 23, 2004 For processes that operate under vacuum conditions, rupture disks with vacuum support ensure that disk does not collapse under differential back-pressure and operates correctly. One-piece vacuum support eliminates potential failure sites and has smooth design that reduces accumulation. Rupture disks are suited for agricultural/bulk powder, aerospace, chemical, gas, petroleum, pharmaceutical, and power applications.
