DOUBLE BLOCK AND BLEED BALL VALVE MANUFACTURERS IN GERMANY

Valvesonly Europe is among the most reputable Double Block and Bleed Ball Valve Manufacturers in Germany, providing innovative valves that are used for secure isolation and easy maintenance in critical systems. Our valves meet global safety standards of operations in many different industries.

What is a Double Block and Bleed Ball Valve?

Double Block and Bleed (DBB) Ball Valve is a very precise valve with two independent sealing surfaces (blocks) and a bleed. It blocks the upstream and downstream sides and at the same time allows the space between them to be bled or vented.

Why Required?

DBB valves are crucial for absolute isolation and zero-leakage uses. Used to ensure operator protection, equipment protection, and maintenance ease without breaking the system. Common in oil & gas pipelines, refineries, and chemical industries.

Key Components of Double Block and Bleed Ball Valve

• Valve Body: Cast or forged steel, stainless steel
• Ball and Seats: Floating or trunnion mounted
• Stems: Anti-blowout
• Bleed Port: For relief from pressure
• Seals: PTFE or metal-to-metal
• Actuation: Manual, gear, pneumatic, or electric actuator

Working Principle

The valve has two separate ball valves in one body or side by side. The two blocks when closed seal off the media, and pressure of the center cavity is vented via the bleed port. This allows zero pressure zones for inspection or repair safely.

Advantages of Double Block and Bleed Ball Valve

• Enhanced safety with double isolation
• Reduces number of valve and fitting requirements
• Space-efficient design with compact construction
• Pressure monitoring permitted in bleed system
• Applicable to high-pressure and hazardous systems

Functions of Double Block and Bleed Ball Valve

• Separates media from each side
• Permits relief of cavity pressure
• Prevents backflow and contamination
• Presents tight shut-off in critical applications
