UNSPSC 40141672: Carbon steel check valve

Check Valve (preventing back flow) made of Carbon steel

UNSPSC 40141672 Carbon steel check valve is a Commodity code under which state and local water utilities and municipal water agencies procure check valves, gate valves, butterfly valves, backflow assemblies, and related water distribution and treatment infrastructure components. The code captures both general water service valves—saddles, couplings, clamps, and ball valves for distribution networks—and specialized engineered equipment such as large-format butterfly valves, detector check valves, quick insertion valves, resilient gate valves, and slide gates for water treatment plants and pressure regulation systems. Issuing bodies include county water departments, municipal water systems, and county boards of commissioners operating water resources divisions. Gwinnett County, Georgia, appears as a repeat buyer, issuing multiple competitive sealed bid and informal quotation solicitations for water infrastructure valves throughout 2026.

Recent activity concentrates in Georgia and Northern California. The City of Marietta, Georgia solicited water service saddles, couplings, clamps, and ball valves under annual contract BL121-26 (RFQ due September 22, 2026); Gwinnett County issued competitive sealed bids for double-offset butterfly valves in sizes 54", 72", 96", and 108" for the Lanier and Shoal Creek Filter Plants (ITB due September 23, 2026, with a virtual pre-bid conference September 2, 2026); DeKalb County, Georgia solicited high-pressure and low-pressure quick insertion valves under a three-year multiyear contract (ITB due August 27, 2026); and Palm Beach County Board of County Commissioners requested quotations for a Reduced Pressure Principle Backflow Assembly, OEM Wilkins (RFQ due August 25, 2026, with SBD small-business preference and local-business preference applicable). Alameda County Water District in California issued an IFB for detector check valves (due July 14, 2026). Gwinnett County also issued multiple informal quotations for Mueller resilient gate and tapping valves in June 2026. All recent opportunities require compliance with AWWA standards, NSF/ANSI 61 certification for drinking-water service where applicable, and submission of references, ethics affidavits, and debarment certifications.
