BS&B Safety Systems GFR-S Reverse Rupture Disc 3 in. Diameter 45 PSIG 132C

The BS&B Safety Systems GFR-S Reverse Rupture Disc is a specialized overpressure relief device designed for use in safety-critical industrial applications, particularly within sanitary and aseptic environments like those found in pharmaceutical, biotechnology, and food processing industries. This specific rupture disc has a 3-inch diameter and is engineered to burst at 45 PSIG (pounds per square inch gauge) at a temperature of 132°C.

A key feature of the GFR-S is its reverse buckling design. In this configuration, the dome of the disc faces towards the process pressure. When overpressure occurs, the disc buckles and reverses, then opens by shearing along a score line, providing instantaneous and full relief. This design makes reverse buckling discs highly resistant to pressure cycling and pulsating conditions, contributing to a longer service life and greater reliability compared to traditional tension-loaded discs. The "GFR-S" model is specifically designed with a smooth internal finish and non-contaminating materials to meet stringent sanitary criteria.

This rupture disc is designed for non-fragmentation upon bursting, meaning the disc material remains attached to the holder, preventing fragments from entering the downstream system. It is suitable for both gas and liquid service and can withstand full vacuum conditions without the need for additional vacuum supports. The BS&B GFR-S Reverse Rupture Disc provides reliable and precise overpressure protection, safeguarding equipment, processes, and personnel in demanding industrial applications.
