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.

How to specify Type 98S DBB Valves. The part number is compiled from a series of generic and alphanumeric codes that define the base unit and options. The structure of the part number is compatible with other range of Budenberg Valves and follow the definition of the valve by defining the Primary Isolation Valve, Vent Valve and the Secondary Isolation Valve in sequence thereafter the material and options are then defined. Typical definition: DBB Valve, flange process inlet, screwed outlet, needle valve vent, 14mm bore primary, and secondary isolation valves, 3/4" NB 300 Raised Face Flange,...
