Double Block & Bleed Valves

Oliver Valves pioneered the Double Block and Bleed (DBB) concept in the early 1980's, which has very much now become a standard world wide.

Each Double Block and Bleed Valve manufactured by them has a unique number recording its factory history.

They offer innovative Double Block and Bleed solutions on a variety of our valves, including Forged Double Block and Bleed's, Instrument Double Block and Bleed's, Injection & Sampling Double Block and Bleed's and Primary Isolation Double Block and Bleed's.

Applications

• Pressure instrument take-off points.
• Sampling systems, where a pipeline probe is integral with our valve.
• Chemical injection systems, where a check valve is part of our valve assembly.
• Drains for tanks and pipes, where space is restricted.
• High pressure firesafe diverter valves.
• Hydraulic power unit systems.
• Reduced vibrational stresses.
• Cost savings with exotic material designs are huge.
