Resideo Braukmann D15S Spares - Complete Valve Insert

**FSTCDFA Forward Acting Rupture Discs: Enhanced Safety for Road and Rail Tankers** The FSTCDFA Forward Acting Rupture Discs are meticulously engineered composite discs comprising four key components: a slotted, perforated metal section; a sealing membrane (typically made from PTFE, but also available in various other metallic and non-metallic materials); a protective segment; and a calibration ring. These discs are specifically designed for installation on road or rail tankers that transport liquids and gases under static, cycling, and pulsating conditions. FSTCDFA discs respond to excessive pressure with a complete opening within milliseconds, making them an excellent choice for valve protection. Additional supports can be supplied for vacuum or counter-pressure protection. **Product Specifications:** - **Sizes:** 2" (DN50), 2.1/2" (DN65), 3" (DN80) - **Materials:** Stainless steel / Membrane: PTFE, PFA - **Rupture Pressure:** Ranges from 3 to 5 bar g - **Tolerance:** ± 5% - **Temperature Resistance:** Up to 265 °C - **Operating Margin:** Up to 80% - **Vacuum Support:** Available - **Fragmentation:** None (membrane only) - **Suitable for Use Under Valves:** Yes - **Corrosion Resistance:** Good - can be enhanced with a PTFE membrane - **Linings:** Yes - **Mounting:** Directly mounted on the container - **Rupture Sensor Options:** Electrical, Magnetic, Inductive, Optical - **PED Certification (CE Mark):** Available - **ATEX EX II 2 GD Certification:** Available To obtain a Rupture Disc Request Form, please download it and send the completed version to sales@flowstar.co.uk.

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.
