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

How to specify Type 98F 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, flange outlet, needle valve vent, 10mm bore primary and secondary isolation valves, 1" NB 150RF x 1" 150RF Flange,...
