Hattersley Fig MH737 PN16 Variable Orifice Double Regulating Valve

**FSDIFDW Double Way Rupture Discs: High-Performance Pressure Relief Solutions** The FSDIFDW Double Way Rupture Discs are expertly engineered composite conventional discs, constructed from four essential components: a slotted, perforated metal section, a seal membrane (primarily made from PTFE, but also available in various metallic and non-metallic materials), a protective layer, and a calibration ring. Designed for installation between flanges, these discs excel in static applications involving both gases and liquids at low pressures. Responding to excessive pressure, the FSDIFDW rupture discs achieve full opening in mere milliseconds, making them an ideal choice for valve protection. For applications requiring vacuum or counter-pressure protection, support options are also available. These composite rupture discs can effectively provide simultaneous protection against both pressure and vacuum scenarios. **Specifications** - **Sizes:** Available in 2" (DN50) to 40" (DN1000) - **Materials:** Stainless steel, Alloy 201, Alloy 400, Alloy 600, Alloy 625, Alloy C276, Titanium; Membrane options include PTFE, PFA, Stainless steel, and Aluminium - **Rupture Pressure:** Ranges from 0.5 to 5 bar g (dependent on material and diameter) - **Krl:** - **Tolerance:** ± 5% to ± 20% - **Temperature Resistance:** Membrane options in PTFE/PFA withstand up to 265°C, with some materials performing up to 480°C (depending on membrane type) - **Operating Margin:** Up to 70% - **Vacuum Support:** Not available - **Fragmentation:** None (membrane only) - **Use Under Valve:** Yes - **Corrosion Resistance:** Good; can be enhanced with a PTFE membrane - **Linings:** Available - **Container Type:** Installed between flanges - **Rupture Sensor Options:** Electrical, Magnetic, Inductive, Optical - **PED Certification (CE Stamp):** Available - **ATEX EX II 2 GD Certification:** Available For more information or to request a quotation, please download our Rupture Disc Request Form and send the completed document to sales@flowstar.co.uk.
