Model: 6MBB & 10MBB DOUBLE BLOCK & BLEED MONOFLANGE WITH OS&Y PRIMARY ISOLATION VALVE The 6MBB is a range of lightweight Monoflange isolation valves that incorporates an Outside Screw and Yoke bolted bonnet primary isolation valve together with heavy duty instrument Needle Heads for the Secondary Isolation and Vent Valves. The compact one piece design not only ensures that potential leakage paths are kept to an absolute minimum but offers significant weight and component cost savings when compared to other conventional installation solutions. The Budenberg 6O Heavy Duty OS&Y Valve is designed to meet the requirements of piping class installations in accordance with ASME/ANSI standards that features all metal seating and metal to metal body / bonnet connections. Outlet Monoflanges are manufactured in a full range of materials, flange types and ratings as well as having a choice of flange, screw or kidney flange outlets. Construction Manufactured from a single piece forging or forged barstock that incorporates the OS&Y Valve Head and outlet connection. Temperature Rating -54 to +538 Deg C (-65 to +1000 Deg F) dependant upon the stem packing material and pressure rating in use. (see datasheet VAC 041 for pressure / temperature performance graph) Configuration Double Block / Isolation and Vent / Bleed Valve Inlet The flanged process connection can be made to suit any International size or rating 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 flange face styles. * API Flanges up to 2.1/16", 3000, 5000 & 10,000 lbs * Norsok L-100 Compact flange design Vent 1/4" NPT female vent as standard, others available upon request Blank and Vent plugs are available (see DSheet VAC-048) Outlet In Flange by Flange variants the outlet flange is identical to the inlet process flange as listed above. Alternatively the output can be: * Screwed female connections, (1/2" NPT standard) * Kidney Flanges for direct connection onto transmitters * Quick release compression fittings Bore Sizes 6mm (standard), 8mm can be provided dependant upon the flange size and rating Fire safe Fire safe to BS 6755 Pt 2 NACE All body & wetted parts materials comply with the requirements of NACE MR 1705 / EN15156 or MR 0103 dependent upon the environmental or application requirement Pressure Rating Pressure rating up to 10,000 psi (690 barg) OS&Y and Needle Valve Assemblies OS&Y and Heavy Duty Needle Valve Head Assemblies incorporate a full range of features including: * Anti static , anti blow-out stems * Self centering, 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 Needle Valve assemblies incorporate 'soft' parent metal sealing rings that are located directly below the head 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, resists all operating pressures and processes. Other Features * Hydro static and Gas Pressure Testing to BS 6755 Pt 1 or API 6A * Material thickness as defined in ANSI / ASME B16.34 * Flange Dimensions as defined in ANSI / ASME B16.5 * Heat code traceable Material Certification to EN 10204 3.1b * Full range of testing, certification and documentation can be supplied including PMI and a full range of NDE Testing * Pressure boundary designs calculated to ASME VIII Div 1 * Designed with 4:1 safety factor * Optional locking and anti tamper head assemblies
