3piece Screwed Ball Valve

Product Name & Standards 3-Piece Screwed Ball ValveCompliant with API 608, ASME B16.34, and ANSI B16.11 standards. Core Definition A versatile flow control valve designed for plumbing and industrial systems, featuring a three-piece construction joined by threaded connections. It incorporates a rotatable ball with a central through bore to regulate the flow and pressure of liquids or gases. Renowned for easy installation, straightforward maintenance, exceptional durability, and long service life, it adapts to a wide range of fluid control applications. Structure & Working Principle – Key Components: Three-piece valve body (upper cover, middle body, lower cover) connected via threads, rotatable spherical plug with a central bore, valve stem, and manual lever handle (or quarter-turn actuator). – Operating Mechanism: Rotating the handle 90 degrees drives the valve stem, rotating the spherical plug-when the plug’s bore aligns with the pipeline, fluid flows freely; when rotated to block the flow path, it shuts off or regulates flow/pressure. The three-piece design allows easy disassembly without removing the valve from the pipeline, facilitating access to internal components. – Connection Method: Threaded (NPT/BSPP) ends for secure, leak-tight integration with threaded pipelines, simplifying on-site assembly. Performance Advantages – Easy installation & maintenance: Threaded connections enable quick mounting, while the three-piece detachable structure allows hassle-free disassembly for cleaning, repair, or seal replacement (no need to disconnect from the pipeline). – Durable & long-lasting: Robust three-piece construction and high-grade materials resist corrosion, wear, and operational stress, ensuring extended service life. – Reliable flow/pressure regulation: Precision-engineered spherical plug and valve seat deliver consistent sealing performance and accurate control over fluid flow and pressure. – Structural flexibility: Modular three-piece design enhances compatibility with different internal components, supporting customization for specific application needs. Key Specifications – Pressure Rating: PN10 – PN250 / Class 150 – 1500. – Operating Temperature: -29℃ – 425℃ (carbon steel body) / -196℃ – 550℃ (stainless steel body). – Body Materials: Carbon Steel (A105), Stainless Steel (304L/316L), Brass (ASTM B16). – Ball Core Material: Stainless Steel (304L/316L), Brass (for low-pressure applications). – Sealing Material: PTFE (Polytetrafluoroethylene) – ensures leak-proof performance and chemical resistance. – Connection Type: Screwed (NPT/BSPP) – compatible with standard threaded pipelines. – Size Range: 1/4″ – 2″ (common threaded valve sizes for general applications). Application Fields – Industrial Systems: Oil & gas distribution, chemical processing, petrochemical low-to-medium pressure pipelines, and process fluid control. – Commercial Infrastructure: Municipal water/gas supply networks, commercial building plumbing, HVAC systems, and fire protection pipelines. – Residential & General Use: Home water/gas lines, small-scale heating systems, and DIY plumbing projects. – Specialized Scenarios: Fluid systems requiring frequent maintenance, precise flow/pressure regulation, and reliable long-term operation (e.g., instrumentation lines, food processing auxiliary pipelines).
