**FSY90RA Reverse Acting Rupture Discs: Advanced Safety Solutions for Pressure Management** The FSY90RA Reverse Acting Rupture Discs are expertly engineered compression or reverse circumference micro-scored discs designed for optimal reliability. Featuring a unique camber, the convex disc maintains its shape under normal operating pressure and only modifies when reaching reverse pressure. These cutting-edge devices can handle pressure ratios of up to 95% between operating and rupture pressure, ensuring thousands of operational cycles without compromising reliability. Upon activation, the FSY90RA disc ruptures instantaneously along the pre-scored line, producing no fragments and achieving a full opening in just a few thousandths of a second. Unlike traditional rupture discs, the FSY90RA offers reduced sensitivity to temperature fluctuations, making them particularly advantageous in applications subject to significant temperature variations. They are especially effective for managing both gas and liquid processes (when a special gas cushion is present) and are ideal for protecting pressure relief valves. The FSY90RA discs are available in a variety of materials and thicknesses, providing exceptional resistance to corrosion. For even greater protection, a PTFE lining can be applied to the process side of the disc. Moreover, vacuum support is not necessary, enhancing installation versatility. **Specifications:** - **Sizes:** 1" (DN25) to 8" (DN200) - **Materials:** Stainless Steel, Alloy 201, Alloy 400, Alloy 600, Alloy 625, Alloy C276, Titanium - **Rupture Pressure:** 0.2 - 70 bar g (depending on material and diameter) - **Tolerance:** +/- 5% to +/- 20% - **Temperature Range:** -196°C to 600°C - **Operating Margin:** 90%, with the potential to reach 95% based on service conditions - **Fragmentation:** None (no fragmentation upon rupture) - **Suitable for Use Under Valves:** Yes - **Corrosion Resistance:** Excellent - **Linings Available:** Yes - **Containers:** FSHR/A, FSHR/P, FSHR/F, FSHTC - **Rupture Sensors:** Electrical, Magnetic, Inductive, Optical - **PED Certification (CE Mark):** Available - **ATEX EX II 2 GD Certification:** Available To order or for more information, please download our Rupture Disc Request Form and send the completed document to sales@flowstar.co.uk. **Optimise your pressure management systems with FSY90RA Reverse Acting Rupture Discs – the reliable choice for safety and efficiency.**
