Product Description Product DescriptionThe Inconel ? 625 Monoflange Double Block and Bleed (DBB) Valve is a compact, high-performance manifold assembly designed for isolation, venting, and pressure monitoring in extreme environments. Crafted from Inconel? 625 (UNS N06625), this valve offers exceptional corrosion resistance, high strength, and thermal stability, making it ideal for oil & gas, chemical processing, aerospace, and subsea applications.Key Features Material Excellence: Inconel ? 625 construction for superior resistance to pitting, crevice corrosion, and oxidation. Double Block and Bleed (DBB): Two independent sealing barriers + bleed port for safe isolation and depressurization. Compact Monoflange Design: Reduced leakage points, lighter weight, and easier installation vs. traditional flange systems. High-Pressure Rating: Suitable for ASME Class 1500 to 4500+ and extreme temperatures (-200°C to +1000°C). Customizable Configurations: Options for threaded, socket weld, or flanged connections; NACE MR0175 compliant.Instrument Types Stainless Steel 316 5 Way Manifolds ValveProduct Description:1.Press up to 10000psig (414bar) for standard stainless steel body2.Temperature for PTFE packing from -65°F to 450°F (-54°C to 232°C) Temperature for Grafoil packing from -65°F to 1200°F (-54°C to 649°C)3.Packing below stem thread isolates the thread lubricant from the media4.Back seating design protects the packing in fully open position5.Non-rotating stem tip6.100% factory testedProduct ParametersTechnical SpecificationsParameterDetailsMaterialBody/Trim: Inconel? 625 (UNS N06625)Design StandardAPI 6D, ASME B16.34, ISO 17292Pressure RatingUp to 10,000 psi (690 bar)Temperature Range-200°C to +1000°C (-328°F to +1832°F)Connection TypesNPT, BSPP, SW, RF Flanges (ANSI/ASME/DIN/JIS)Sealing TechnologyMetal-to-metal seals, graphite/gasket optionsApplicationsOffshore platforms, chemical injection, sour gas, cryogenic systems1. Instrumentation Manifolds Features:? Efficiency Improvement and Energy Saving.? Suitable for confined spaces as its compact size.? Installation cost-saving as its elaborate design.? Miner leakage possibility leads to low maintenance.? Fewer connections improve system layout.Advantages Over Traditional ValvesSafety: DBB design ensures zero leakage during maintenance or failure.Space-Saving: Monoflange integration eliminates multiple pipe fittings.Cost-Effective: Reduced installation time and lifecycle maintenance costs.Durability: Inconel ? 625 resists chloride stress corrosion cracking (SCC) and sour service (H2S). ApplicationsOil & Gas: Wellhead controls, Christmas tree manifolds, pipeline isolation.Chemical Processing: Acid handling, high-purity fluid systems.Power Generation: Nuclear, supercritical CO systems.Aerospace: Hydraulic and fuel systems.Detailed Photos
