Model: 98F
PRIMARY ISOLATION VALVES
SINGLE FORGED BODY

The 98F is a full range of flange x flange, Single and Double
Block & Bleed and Bleed valves manufactured from a one piece
forging or forged barstock. The 98F has industry standard hub
or flanged end connections to suit any customer requirement.
Manufactured from a single piece of material ensures that the unit
has superior grain flow and strength around the flange / body.
It can be provided in a full range of configurations of Single Block
or Double Block and Bleed incorporating Budenberg Heavy Duty
Needled Vales, OS&Y Isolation Valves or fully floating Ball Valve
assemblies.
As units are manufactured to suit the individual customer needs
therefore we are able to offer a full range of special configurations
or connections or materials. All units are wholly designed and
manufactured by Budenberg Ltd and as such can be provided
with the full range of material and product testing including
documentation and certification.

Construction
Integrally forged and machined one piece body and flanges to
give superior grain flow around the flange /body area providing
exceptional strength
Configurations
Single Block
Single Block & Bleed
Double Block
Double Block & Bleed
* Optional Check Valves can be fitted into the inlet or outlet
* Optional Quills can be fitted into the inlet for Injection or
sampling applications
* Other configurations can be supplied to suit any existing or
new application requirements
Inlet & Outlet
The flanged end connections can be of different types,
sizes, ratings and materials including, but not restricted to:
* ANSI B16.5 Flanges from 1/2" to 4" in ratings from 150 to
2500 lbs in RF, FF, SRF and RTJ
* API Flanges up to 2.1/16", 3000, 5000 & 10,000 lbs
* Hub End connections including Techlok, Norsok, Graylok etc
Vent
Standard Vent connection is 1/2" NPT f screwed connection
but this can be changed to offer other connections type and sizes.
Bore Sizes
The through bore of the unit is dependant upon the type of
valve selected for the Primary and Secondary Isolation Valves
The vent valve is offset from the main bore and therefore can
be of a different style and bore.
Ball Valves 10 mm, 14 mm and 20 mm
PEEK™ seats available on request.
Materials
Units manufactured from forgings or forged barstock to meet
the individual specification requirements. Standard Materials

Standard Features
Ball Valve Assemblies
Fully Floating Ball Valve Assemblies with cavity relief through
the seats.
Needle & OS&Y Valve Assemblies
Both Heavy Duty Needle & OS&Y Valve Head Assemblies both
incorporate a full range of features including:
* Anti static , anti blow-out stems
* Self centring, non-rotating stem tips provide a true metal to
metal valve seat whereby the material of the stem tip is one
grade harder than the body thus resisting over tightening,
preventing wear and guaranteeing a 100% bubble tight seat
closure, first time, every time
No Threads in the process stream
All Ball, Needle & OS&Y valve assemblies incorporate a 'soft'
parent metal sealing rings that are located directly below the
head and connection adaptors to ensure that no threads are
directly in the process stream
Stem Packing
Fully adjustable, dynamically responsive multi ring gland
sandwich', in either PTFE or Graphoil, resist all operating pressur
and processes. Budenberg offer 100% gland integrity for the
lifetime of every valve
Other Features
* Hydro static and or Gas Pressure Testing to BS 6755 Pt 1
* Fire safe to BS 6755 Pt 2
* Material thickness as defined in ANSI / ASME B16.34
* Flange Dimensions as defined in ANSI / ASME B16.5
* Standard Material Certification to EN 10204 3.1b
* Can be manufactured in a full range of standard and special
materials to suit the application
