The FSDCDS Sanitary Rupture Discs are designed for aseptic applications, consisting of a slotted, perforated metal section, a seal membrane (commonly PTFE, with other materials available), and a protective layer. Ideal for use with gas or liquids under static or low-pressure conditions, these discs open fully within milliseconds during overpressure events, without fragmentation. They can be fitted with supports for vacuum and counter-pressure protection, allowing simultaneous protection against both. PTFE gaskets certified to FDA, USP Class VI, 3-A, and EU 10/2011 standards make installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection) simple. The FSDCDS is also suitable for C.O.P. (Clean-Out-Of-Place) applications.
