In today’s advanced industrial sectors—especially oil and gas, petrochemicals, and thermal power—processes operate at pressures that demand an exceptionally rugged and dependable isolation system. The DBB 90 Double Block and Bleed Valve is specifically designed for such ultra-high-pressure environments where safety, reliability, and leak-proof performance are critical.
This valve delivers two effective barriers and a bleed mechanism in one integrated unit, providing enhanced control and operational assurance even under pressures exceeding 90 bar. Engineered for maximum safety and minimal maintenance, the DBB 90 is a robust alternative to traditional block and bleed assemblies.
Key Features of DBB 90 Valve
Pressure Rating: Exceeds 90 bar; suitable for ANSI 900–1500 class applications
Material Options: Stainless steel, duplex, super duplex, and special alloys
Fire-Safe and Emission Control: Compliant with API 607, ISO 15848-1, and PED directives
Compact Body: One-piece forged construction for strength and minimal leak paths
Bleed Functionality: Central bleed port allows safe pressure equalization and venting
Industrial Applications
The DBB 90 is trusted in systems that experience fluctuating pressures and hazardous fluids:
High-Pressure Separators in Upstream Oil Facilities
Wellhead Control Panels
Hydrocarbon Measurement Systems
Compressor Station Pipelines
Amine and Desalting Skids in Refineries
These critical systems require valves that ensure absolute shut-off without failure or compromise.
Advantages Over Conventional Systems
Enhanced Safety: Dual isolation with integrated bleed minimizes exposure risks during maintenance
Operational Efficiency: Quick isolation and venting reduce process downtime
Simplified Layout: One valve replaces three, reducing weight and space requirements
Automation-Friendly: Compatible with electric and pneumatic actuators
When system reliability must be uncompromised under high pressure and critical conditions, the DBB 90 valve is the solution of choice. It ensures uninterrupted system integrity, quick serviceability, and long-term operational safety.
