2piece Screwed Full Bore Ball Valve

Product Name & Standards Two-Piece Screwed Full-Bore Ball ValveCompliant with API 608, ASME B16.34, and ANSI B16.11 standards. Core Definition A specialized flow control valve featuring a two-piece construction with threaded connections on both ends. Designed with a full-bore opening that enables unrestricted fluid flow, it utilizes a rotatable ball to control on-off operation-rotating the ball aligns or blocks the full-bore passage, regulating fluid flow reliably. Widely used in water, gas, and oil systems, it combines robust performance, cost-effectiveness, and long-term reliability. Structure & Working Principle – Key Components: Two-piece valve body (threaded for assembly), full-bore spherical plug (matches pipeline inner diameter), valve stem, and manual lever handle (or quarter-turn actuator). – Operating Mechanism: Rotating the handle 90 degrees drives the valve stem and spherical plug-when the plug’s full-bore through hole aligns with the pipeline, fluid flows unobstructed (valve open); rotating the plug to block the flow path shuts off flow (valve closed). The two-piece design allows easy disassembly for maintenance or replacement. – Connection Method: Threaded (NPT/BSPP) ends for secure, leak-tight integration with threaded pipelines, simplifying on-site installation. Performance Advantages – Unrestricted flow: Full-bore design minimizes pressure loss and turbulence, ensuring efficient fluid transmission (ideal for media with minimal particle content). – Reliable operation: Robust two-piece construction and precision-engineered ball valve seat deliver consistent leak-proof performance and structural durability. – Cost-effective: Balances high performance with competitive pricing, suitable for large-scale installation and budget-conscious projects. – Versatile media compatibility: Optimized for water, gas, and oil systems, adapting to commercial, industrial, and residential applications. – Easy maintenance: Two-piece detachable design facilitates access to internal components for cleaning, repair, or seal replacement. 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 reliable sealing and chemical resistance. – Connection Type: Screwed (NPT/BSPP) – compatible with standard threaded pipelines. – Size Range: 1/4″ – 2″ (common full-bore threaded valve sizes). Application Fields – Industrial Systems: Oil & gas distribution, petrochemical low-pressure pipelines, and process fluid transmission. – Commercial Infrastructure: Municipal gas/water supply networks, commercial building plumbing, and HVAC systems. – Residential & General Use: Home water/gas lines, small-scale heating systems, and DIY plumbing projects. – Specialized Scenarios: Low-to-medium pressure fluid systems requiring unrestricted flow and cost-effective on-off control.
