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

The 3-Piece Ball Valve -- Threaded / Socket Weld SS316 is designed, manufactured, and tested in accordance with applicable API / ASME / BS / ISO international standards. Compliance documentation and Material Test Certificates (EN 10204 3.1) are provided with every order.
Standard construction is carbon steel, stainless steel (CF8 / CF8M), and special alloy grades. Alternative and upgraded grades -- Duplex, Super Duplex, Inconel, Monel, Hastelloy, and NACE MR0175 trims for sour service -- are available on request.
It is offered in a range of sizes as per the technical specification with standard ANSI / ASME pressure classes (PN ratings on request). End connections include flanged (RF / RTJ), butt-weld, socket-weld, and screwed ends as per specification.
Yes. Supreme Valves India is an established exporter of industrial valves to Saudi Arabia (KSA), the UAE, Qatar, Kuwait, Oman, Bahrain, and across the Gulf. We provide sea-worthy export packing, EN 10204 3.1 / 3.2 certification, certificate of origin, and support for SABER / SASO conformity on KSA shipments.
Every valve undergoes hydrostatic shell and seat testing per API 598 / ISO 5208. Documentation includes EN 10204 3.1 MTC (3.2 on request), NDT reports, and fire-safe (API 607) or NACE MR0175 certification where applicable. Third-party inspection by TÜV, SGS, Bureau Veritas, or Lloyd's Register can be arranged.
Order quantities are flexible -- from single units for stocked items to bulk volumes for project requirements. Lead time depends on size, material, and quantity; please contact our team with your specification for a firm delivery schedule and quotation.
