Technical Datasheet -- Ductile Iron Gate Valves for Water, Wastewater, and Industrial Service
Ductile iron gate valves for water distribution, wastewater, and general industrial service. Ductile iron EN-GJS-500-7 (GGG50) body provides the strength of steel (500 MPa tensile) with the castability and cost advantage of iron. Metal-seated (bronze or SS316 seat ring) for industrial and steam service, or resilient seated (EPDM or NBR rubber seat) for bubble-tight water and wastewater shutoff. OS&Y rising stem for above-ground visual indication, or NRS non-rising stem for buried service. Epoxy-coated internal and external surfaces per AWWA C550 / EN 14901. Flanged or socket ends. EN 1171 / BS 5163 / AWWA C500 / ASME B16.34 compliant.

The Ductile Iron Gate Valve -- Flanged PN16 EPDM Water 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.
