The 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.
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 Valve
