DBB 70 – High-Performance Double Block and Bleed Valve for Demanding Process Environments

 In high-stakes industrial settings such as oil and gas processing, chemical manufacturing, and power generation, safe and reliable system isolation is crucial. The DBB 70 Double Block and Bleed Valve is a premium solution engineered to meet these challenges head-on. With its integrated double block and bleed configuration, this valve provides a compact, efficient, and safe alternative to traditional multi-valve systems.

The DBB 70 is specifically designed to deliver leak-tight performance, reduce space and weight, and ensure compliance with the most stringent safety standards. This article explores the unique capabilities of the DBB 70 and its role in modern industrial operations.

Key Design Features of the DBB 70

The DBB 70 combines two isolation valves and a bleed valve into a single compact body. This innovative design reduces installation time, limits the number of potential leak paths, and simplifies system layouts.

• Pressure Rating: Rated for up to 70 bar, with customization options for higher classes (ANSI 600–900)

• Materials: Corrosion-resistant stainless steel, carbon steel, or exotic alloys available

• Sealing Options: Soft-seated or metal-seated with fire-safe graphite backup

• Compact Body: One-piece forged construction ensures strength and leak integrity

• Compliance: Meets API 607, ISO 15848, and PED standards for fire safety and fugitive emissions

Operational Advantages

• Leak Prevention: Dual isolation ensures process fluids are safely contained during maintenance or system shutdown

• Space and Weight Savings: The integrated design reduces the footprint and number of fittings required

• Reduced Downtime: Easy access and quick operation improve maintenance cycles

• Fire-Safe and Emission-Compliant: Backed by third-party testing, it ensures performance under fire and leak-risk conditions
