Model: MVS PRIMARY ISOLATION VALVES MODULAR CONSTRUCTION The model MVS is a three piece modular valve that can be readily configured into a full range of Single or Double Block & Bleed Valves that provide primary isolation when directly mounted onto process pipework or vessels. The MVS provides an industry standard flanged inlet connection and a screwed vent and outlet connection to suit any instrumentation or take off requirement. The central body of the MVS is available in any combination of Ball, Heavy Duty Needle or OS&Y Isolation to which industry standard flanged, hub and screwed end connections are bolted. The design of the end connections incorporate the detail that directly secures the Ball Assembly in position thereby ensuring a single piece of material up to and including the first Primary Isolation Valve The modularity of the MVS therefore provides a cost effective yet limitless choice of configurations and materials that make it the perfect choice for your primary isolation requirements. All units can be supplied with a full range of testing, certification and documentation to meet any project requirement Construction Three piece modular construction comprising of a central body housing all the valve assemblies on to which a choice of flange, hub end or screwed connections are bolted 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 MVS 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

How to specify Type MVS 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, 10mm bore primary and secondary isolation valves, 1.5" NB 900 RTJ Face Flange, 1/2"...
