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.
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.
