Flanged End Ball Valve

Product Name & Standards Flanged Ball ValveCompliant with API 608, ASME B16.34, and ANSI B16.5 standards. Core Definition A specialized flow control valve engineered for piping systems, designed to regulate fluid flow through a hollow spherical plug with a central through bore. Featuring flanged connections on both ends for secure pipeline integration, it combines reliable on-off operation with precise flow regulation capabilities, delivering user-friendly performance in industrial and commercial applications. Structure & Working Principle – Key Components: Dual flanged valve body (round, hollow construction), spherical plug with a central through bore, valve stem, and manual handle (or automated actuator). – Operating Mechanism: Rotating the handle drives the valve stem, which rotates the spherical plug-when the plug’s through bore aligns with the pipeline, fluid flows freely (valve open); when rotated 90 degrees, the plug blocks the flow path (valve closed), enabling rapid on-off control and fine-tuning of flow rates. – Connection Method: Flanged ends bolted to matching pipe flanges, ensuring leak-tight sealing and straightforward installation/maintenance. Performance Advantages – Versatile functionality: Suitable for both on-off shutoff and flow regulation, adapting to diverse process requirements. – Reliable operation: Robust spherical plug design and precision sealing surfaces ensure long-term leak-proof performance and structural durability. – Easy to use: 90-degree quarter-turn operation enables quick opening/closing, reducing operational complexity; intuitive handle control simplifies flow adjustment. – Low flow resistance: Hollow spherical plug design minimizes pressure loss, ensuring efficient fluid transmission. Key Specifications – Pressure Rating: PN10 – PN420 / Class 150 – 2500. – Operating Temperature: -29℃ – 425℃ (carbon steel body) / -196℃ – 550℃ (stainless steel body). – Body Materials: Carbon Steel (A216 WCB), Stainless Steel (A351 CF8/CF8M), Alloy Steel (A217 WC6/WC9). – End Connection: Flanged (ANSI B16.5, DIN EN 1092-1) – compatible with standard industrial pipeline flanges. Application Fields – Industrial Piping Systems: Oil & gas transmission, chemical processing, petrochemicals, power generation, water treatment, metallurgy, and process pipelines. – Commercial & Infrastructure: Municipal water supply, HVAC systems, industrial boilers, compressed air lines, and commercial building fluid control networks. – Specialized Applications: High-pressure fluid transmission, corrosive media handling, and piping systems requiring both rapid shutoff and precise flow regulation.
