Oliver Valves\u2019 Double Block and Bleed (DBB) Valves are precision-engineered to deliver true double isolation and positive sealing for maximum safety and efficiency. Designed as a modular, one-piece solution, the DBB valve eliminates the need for multiple valve assemblies, offering significant savings in space, weight, and installation cost compared to traditional three-valve configurations. Built for demanding applications, Oliver DBB valves provide reliable isolation and leak-tight performance for pressure instrument interfaces, vents, drains, sample and injection points, purge systems, and process flow isolation\u2014particularly in systems handling hazardous, high-pressure, or critical fluids. With a compact and fully integrated design, these valves remove the necessity for welding or bolting multiple components together. This not only reduces installation time and labor costs but also minimizes potential leak paths, improving overall safety and long-term performance.

Machined from a single piece upset forging, our \u2018N\u2019 Type Double Block and Bleed Valves feature two-needle primary and secondary isolating valves and a needle valve. With a range of different operating temperatures and configurations, our Double Block and Bleed Valves are the superior market leader.\u00a0Oliver Valves Double Block and Bleed valves provide Metal seating, with a 5.4mm bore for many applications without having to resort to traditional single isolate valves.\u00a0<\/span>Oliver Valves\u2019 standard \u2018N\u2019 Type DBB range from 150lb up to 2500lb, but can also be rated to 10,000psi.<\/span><\/p>

The N-type forged DBB valve is available in Stainless Steel, Carbon Steel, Duplex, Super Duplex and many other materials on request. We have various connection types and sizes are available, from Flanged, Hub, Threaded, to Welded. The standard temperature range up to 540 Deg C, depending on materials. All NPT connection threads are Single Point CNC machined.\u00a0All Oliver products have material traceability and pressure test certificates to BS EN 10204 3.1. A unique code is stamped on all valve bodies linking them to their material and chemical analysis certificates.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
