**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.**

A Tri-Clamp gasket, also known as a Tri-Clover gasket, is a sanitary sealing element designed for use between two ferrules within a Tri-Clamp fitting system. These gaskets provide a leak-proof and hygienic seal, making them essential for piping systems in the food, beverage, pharmaceutical, and biotechnology sectors.

Our Tri-Clamp gaskets are specifically manufactured for the Food & Dairy, Chemical, and Pharmaceutical industries, where standard tube and pipe couplings are critical for operational efficiency.

All gaskets are FDA approved and are supplied as Type 2 Lipped as standard, facilitating easy assembly.

Elastomer Gaskets – EPDM, Silicone & VITON®

These gaskets are engineered to ensure a smooth transition throughout the bore when fully assembled. To maintain this quality, all our Elastomer gaskets are produced with a shore hardness of 75/85 IRHD. They comply with FDA regulations concerning rubber and rubber-like materials as specified in Title 21, paragraph 177.2660, and meet Class 1 material classification of the 3A sanitary standards in the USDA and standard 51 of the NSF. Our Elastomer range is also colour coded for easy identification: EPDM = Black/Blue, VITON® = Green, Silicone = White/Clear.

PTFE Solid (Teflon®)

The PTFE Solid gaskets are meticulously manufactured from solid billets of virgin PTFE, possessing a hardness of 60/65 shore D, ensuring precision components with low porosity properties. These gaskets are also produced in accordance with FDA regulations for Teflon® and fluorocarbon resin materials as outlined in Title 21, paragraph 177.1550, suitable for contact with foodstuffs. Additionally, they satisfy Class 1 material classification of the 3A sanitary standards, enabling us to provide custom sizes to meet specific customer requirements, with most requests for non-standard components readily accommodated.

PTFE Envelope (Teflon®)

Envelope gaskets feature a composite construction, combining a PTFE (Teflon®) outer layer with a VITON® filler as standard. This design ensures a seal with a degree of elasticity, delivering excellent sealing properties alongside flexibility. The PTFE component is specified to have a hardness of 60/65 shore D and is crafted from a solid billet of virgin PTFE (Teflon®). This construction minimises the risk of stress cracking in the product contact area, thereby enhancing the aseptic qualities of the sealing system. Envelope gaskets are solely manufactured from compounds that comply with FDA regulations for Teflon® and fluorocarbon resin materials, as stated in Title 21, paragraph 177.1550, suitable for food contact, and also meet the Class 1 material classification of the 3A sanitary standards. We offer special sizes to meet customer needs, and our manufacturing process allows for variations in filler materials and bespoke components as required.
