Hattersley Fig 100CTH PN16 Ball Valve - T-Handle

**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.**

The Fig. 970 and 970G valves feature a robust ductile iron body with an integrated notch plate, anti-blowout stem, and fully bonded epoxy coating for Level 3 C3 corrosion protection. Maintenance-free design reduces downtime, while DN250+ valves include a gear operator. Suitable for flow regulation and gas applications, they comply with BS EN 593/558 and are approved for Group 1 & 2 gases and liquids (PED 2014/68/EU). Rated PN16, -10 to 130°C.

The PREL101003 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system at a predetermined pressure, providing essential protection against over-pressurisation within heating systems. The Reliance 101 Series Pressure Relief Valves are widely utilised as a crucial safety feature in sealed heating installations. Upon installation, the valve is calibrated to the correct pressure. If the pressure within the system exceeds this set threshold, the valve automatically opens, releasing water into the atmosphere. This functionality effectively prevents the system from reaching hazardous pressure levels that could potentially cause damage and pose risks to individuals nearby.

Features and Benefits:

• Diaphragm design enhances resistance to scaling, resulting in a longer lifespan.
• The straightforward removal of the single-piece cartridge allows easy access for cleaning or replacement.
• Set relief pressure range from 2.0 bar to 6.0 bar provides flexibility in system design.
• Available with FSBP or MBSP/FBSP connections for optimal installation versatility.
• Exclusively suitable for heating applications.
