Product Description Product DescriptionComprehensive Product Introduction: Rosemount 0305 Five-Valve Manifold1. Product OverviewThe Rosemount 0305 Series five-valve manifolds (e.g., 0305RC53B11) are precision-engineered solutions designed for integration with differential pressure (DP) transmitters, including Rosemount's 3051S, 3051, and 2051 series. As part of Emerson's Coplanar? platform, these manifolds eliminate traditional flange connections, reducing potential leak points by 50% while offering a compact, lightweight design for high-reliability pressure management in critical industrial processes.Key Features:Factory Integration: Pre-assembled, leak-tested, and calibrated with transmitters for plug-and-play installation, ensuring zero field assembly errors.Valve Configuration: Five-valve design includes two isolation valves, two vent/drain valves, and one equalizing valve, enabling instrument isolation, pressure equalization, and safe fluid venting without process interruption.Material Robustness: Constructed from 316/316L stainless steel with PTFE/graphite packing, compliant with NACE MR0175/ISO 15156 for sour service and corrosive environments.Detailed Photos2. Engineering Innovations 2.1 Coplanar? TechnologyThe 0305 series utilizes Rosemount's proprietary Coplanar design, aligning valve ports coplanar to the transmitter's sensor. This innovation:Reduces Leak Paths: Eliminates flange bolts and gaskets, cutting leakage risks by 50%.Saves Space & Weight: 40% lighter than conventional manifolds, ideal for space-constrained installations.2.2 PressureLock? Valve TechnologyTwo-Piece Stem Design: Separates stem threads from process media, preventing corrosion and blowouts. Enhances valve lifespan by 30% in high-cycle applications.Metal-to-Metal Seating: Ensures leak-tight shutoff up to 431 bar (6,250 psi) and 399°C (750°F), exceeding ISO 5208 Leak Rate A standards.2.3 Configuration FlexibilityProcess Connections: Standard ?"-14 NPT female ports for direct pipeline and transmitter mounting. Optional IEC flanged or DIN-compliant connections for global compatibility.Orientation Options: Radial, parallel, or 90° valve handle alignments to accommodate complex piping layouts.Product ParametersParameterSpecificationMax Operating Pressure431 bar (6,250 psi)Max Temperature399°C (750°F)Body Material316/316L stainless steelPacking MaterialPTFE/graphite (standard); graphite (high-temp)Valve TypeIsolation, equalization, vent/drainLeak RateISO 5208 Rate A (zero visible leakage)ComplianceNACE MR0175, ASME B31.1, ATEX/IECExWarranty1-5 years (extended options available)4. ApplicationsThe 0305 five-valve manifold is optimized for:Differential Pressure Measurement: Safely isolates, equalizes, and vents DP transmitters in flow, level, and filtration systems.Critical Industries:Oil & Gas: Wellhead monitoring, separator level control (H2S-resistant design).Power Generation: Steam turbine pressure monitoring Chemical Processing: Reactor vessel leak detection.Safety Functions: Vent valves enable emergency depressurization; equalization valves prevent transmitter overpressure during calibration.5. Installation and Maintenance5.1 Installation Best PracticesDirect Coplanar Mounting: Bolt manifold directly to transmitter interface using integrated hardware (torque: 40-50 N·m).Process Connection: Thread pipeline fittings into NPT ports; avoid over-tightening to prevent thread damage.Leak Verification: Perform post-installation bubble tests despite factory testing.5.2 Calibration and OperationZero Calibration: Close isolation valves, open equalizing valve to balance pressure, then open vent valves for zero adjustment.Venting/Draining: Open vent valves slowly to release trapped fluids; use drain valves for slurry or viscous media 5.3 Maintenance ProtocolAnnual Inspection: Check stem seals and packing for wear; replace PTFE every 5 years or after 10,000 cycles.Cleaning: Flush with solvents compatible with 316SS/PTFE (e.g., isopropyl alcohol).Stem Lubrication: Apply high-temperature anti-seize lubricant for smooth operation.6. Ordering and Compatibility6.1 Model Number BreakdownExample: 0305RC53B110305: Coplanar manifold series.R: Manufacturer (Rosemount).C: Manifold style (Coplanar).53: Five-valve configuration.B: 316SS body.11: PTFE packing + integral seat.6.2 Pricing and ConfigurationsStandalone Unit: ~950-950-1,200 (varies by distributor).Transmitter Bundles: Cost-saving packages with Rosemount 3051S transmitters (e.g., 3051S1A/A2A+0305RC53B11).Options:Natural Gas Metering Pattern (e.g., 0305RC56B11): Soft-seat valves for precise flow control.NACE Bolting: For hydrogen sulfide environments.7. Competitive AdvantagesReliability: PressureLock? valves reduce field failures by 30% vs. conventional manifolds.Efficiency: 15-minute installation vs. 1+ hour for flange-based systems.Eco-Compliance: Fewer leak points minimize fugitive emissions (EPA/ISO 15848-1).Versatility: Supports all Rosemount DP transmitters (2088, 4088, 3051 series).8. ConclusionThe Rosemount 0305 five-valve manifold sets the industry benchmark for safety, efficiency, and durability in pressure management. Its Coplanar? integration, PressureLock? technology, and rigorous compliance standards make it indispensable for critical applications in oil/gas, power, and chemical sectors.
