NABIC 542 - Spares Kit

**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.**

Product Specification

Our comprehensive range of valves is available in various sizes: 15NB, 20NB, 25NB, 32NB, 40NB, 50NB, 65NB, and 80NB. Each valve features a male BSP inlet and a female BSP outlet, ensuring compatibility with most systems.

Constructed from high-quality gunmetal or stainless steel, our valves offer durability and reliability. The disk options vary by size, with all sizes utilising a robust metal-to-metal design, while the 15NB to 50NB variants offer the added advantage of a Viton disk.

Each valve is equipped with 'O' Rings made from nitrile, providing effective sealing for a range of applications. These valves are suitable for use with compressed air, gases, water, oil, and steam, making them incredibly versatile.

The set pressure for our valves ranges from 0.35 to 24 Barg for sizes 15NB to 50NB, and from 0.35 to 13.79 Barg for the 65NB to 80NB sizes. They can operate at a maximum temperature of 200°C, ensuring performance even in demanding conditions.

Enhance your systems with our reliable valves, engineered for optimal performance and longevity. Explore our selection to find the perfect size for your needs.

Important Note: The DN value embossed on the valve body signifies the NABIC 500 body size used in the manufacture of this valve and does not correspond to the inlet or outlet size. For instance, a valve with 1" connections (DN25) employs a DN20 NABIC 500 valve body, which is why it will have DN20 marked on the side of the valve.
