II. Key Attribute Parameters
\nSize & Pressure
\nPort Size: 1\/2\u2033~40\u2033 (DN15~DN1000), covering small to large-diameter pipelines. From 1\/2\u2033 instrument lines to 24\u2033 main process pipelines, it adapts to diverse flow control needs, ensuring compatibility with standard industrial layouts.
\nPressure Rating: 150LB~1500LB (2.0MPa~10.0MPa). 150LB suits low-pressure systems (e.g., municipal water); 300LB\/600LB handle medium to high pressure (e.g., oil transmission, steam pipelines).
\nMaterial & Sealing
\nBody & Bonnet: WCB cast carbon steel (ASTM A216), offering high strength (tensile strength \u2265485MPa) and temperature resistance up to 425\u2103. It withstands water, oil, gas, and mild industrial fluids without corrosion in non-aggressive environments.
\nSeal Components:
\nValve Seat\/Disc: Metal-to-metal (13Cr stainless steel or stellite coated) for high pressure\/temperature; optional PTFE soft seals for corrosive media. Stellite\u2019s hardness (HRC55~60) resists wear from frequent operation.
\nFlange Gaskets: Graphite (for high temperature) or PTFE (for chemicals), ensuring leak-tight flange connections per standard specifications.
\nStem: 2Cr13 alloy steel, corrosion-resistant and torque-resistant, preventing seizing during manual operation.
\nConnection & Operation
\nConnection Type: Flanged (RF\/FF\/RTJ), compatible with ANSI B16.5 (US), BS 10 (UK), DIN 2501 (EU), and JIS B2220 (Japan) standards. This flexibility allows integration into global pipeline systems without adaptation.
\nActuation: Manual (handwheel), with precision threading for fine flow adjustment. The handwheel\u2019s ergonomic design reduces operator fatigue during frequent throttling (e.g., regulating boiler water level).
\nStandards Compliance
\nDesign & Manufacturing: API 602 (small sizes), API 600 (large sizes), ANSI B16.34 (pressure-temperature ratings).
\nTesting: API 598 (hydrostatic shell test at 1.5\u00d7rated pressure; seat test at 1.1\u00d7rated pressure) to verify strength and sealing.
\nProduct Overview
\nIII. Features Description
\nPrecise Throttling Control: The globe valve\u2019s linear stem movement (disc lifts\/lowers perpendicular to flow) creates a variable flow area, enabling fine flow rate adjustment. This makes it superior to ball valves for applications requiring stable regulation (e.g., controlling fuel supply to industrial burners).
\nGlobal Standard Compatibility: Flange dimensions, face-to-face lengths, and pressure ratings align with ANSI, BS, DIN, JIS, and API standards. This eliminates installation barriers in cross-border projects, from North American refineries to European chemical plants.
\nMetal Hard Sealing Reliability: Metal-to-metal seals maintain tight shut-off under 600LB pressure and 425\u2103 temperature, outperforming soft seals in high-pressure steam or hot oil systems. They avoid degradation from heat or pressure surges, ensuring long-term sealing integrity.
\nCost-Effective Durability: WCB material balances performance and cost, avoiding the premium of stainless steel for non-corrosive media. Cast construction eliminates internal defects, while precision-machined components reduce maintenance needs, lowering lifecycle costs.
\nStraightforward Maintenance: Flanged connections allow easy disassembly for seal replacement or stem lubrication. Standardized parts (e.g., gaskets, stems) simplify spare part procurement globally.
\nIV. Manufacturing Processes
\nCasting: WCB steel is melted and poured into precision molds. Automated casting ensures uniform density; post-casting annealing relieves internal stresses to prevent warping.
\nMachining: Valve body, disc, and stem are CNC-machined to tight tolerances (\u00b10.02mm). Seal faces are ground to Ra \u22641.6\u03bcm, ensuring uniform contact between seat and disc for tight sealing.
\nSeal Assembly: Metal seats are press-fitted or welded into the body; stellite coating is applied via plasma welding, then lapped for flatness. Flange gasket grooves are machined to match standard dimensions (e.g., ANSI B16.5 RTJ grooves).
\nTesting:
\nHydrostatic Shell Test: 150LB valves tested at 3.0MPa, 600LB at 15.0MPa for 30 minutes to check for body leaks.
\nSeat Leakage Test: 1.1\u00d7rated pressure (e.g., 2.2MPa for 150LB) with water, ensuring leakage \u22640.1\u00d7DN (mm)\/min (API 598 standards).
\nOperation Test: 100+ open\/close cycles verify smooth handwheel operation and consistent sealing.<\/p>\n","protected":false},"excerpt":{"rendered":"
