3-Piece Ball Valve -- Threaded / Socket Weld SS316

Technical Datasheet -- Three-Piece Ball Valves for In-Line Maintenance

Document No.SV-DATA-3PBV-001
RevisionA
DateMay 2026
ManufacturerSupreme Valves India, Ahmedabad, Gujarat, India

Three-piece ball valves for in-line maintenance without removing the valve from the pipeline. Body consists of two end pieces and a central section -- the centre can be removed for ball, seat, and stem servicing while the end connections remain in the pipeline. Threaded NPT/BSP, socket weld, butt weld, or tri-clamp ends. SS316 investment cast or barstock body. Full bore with PTFE/RPTFE/PEEK seats. Bubble-tight shutoff per API 598 Class A. Anti-blowout stem. ISO 5211 direct mount pad for actuators. API 608 / ISO 17292 / BS EN ISO 5211 compliant.
