The Relief Valve DN15/0 is designed, manufactured, and tested in accordance with AWWA C512 (Air Release, Air/Vacuum Valves for Water) / EN 12266. 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 DN25 (1") to DN300 (12") with PN10 / PN16 (10 bar / 16 bar) / Class 125# / Class 150#. 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.
