Model: 98S
PRIMARY ISOLATION VALVES
SINGLE FORGED BODY

The model 98S comprises of a full range of Single or Double
Block & Bleed Valves that provide primary isolation when
directly mounted onto process pipework or vessels. The 98S
provides an industry standard flanged inlet connection and a
screwed vent and outlet connection to suit any instrumentation
or take off requirement.
The type 98S is available in a multitude of configurations
including Single Block, Double Block or Double Block and Bleed
incorporating Budenberg Heavy Duty Needle Valves, OS&Y
Isolation Valves or fully floating Ball Valve Assemblies as
detailed in additional Datasheets
In addition, the 98 series offers a virtual limitless array of options
and materials that make it the perfect choice for your primary
isolation requirements. All units are wholly designed and
manufactured by Budenberg Ltd and can therefore be supplied
with a full spectrum of certification, testing and documentation
to meet any project requirement.

Construction
Integrally forged one piece body 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
Inlet
Type 98S units can be manufactured with any flange type
including:
* 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
Outlet
1/2" to 2" screwed outlets to ANSI / ASME B1.20.1
Socket Weld and Butt Weld outlets are available but may be
extended to protect internal components within the valve head
assembly. All outlet connections are secured to prevent
accidental dis-assembly
Vent
Standard Vent connection is 1/2" NPT f screwed connection
but this can be changed to suit the customer requirement
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

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

Options
PEEK™ seats available on request.
