UNSPSC 40141679: Concentric butterfly valve

Butterfly valve with Concentric type construction made of all materials & services

UNSPSC 40141679 Concentric butterfly valve is a Commodity code covering fluid-control devices that state and local water utilities procure as components of treatment plant, water distribution, and backflow prevention systems. Under this code, buyers acquire butterfly valves in a range of sizes and configurations—from small inline check valves to large industrial gate valves with motor operators—along with related accessories such as gearboxes, tapping sleeves, resilient wedge inserts, and quick insertion equipment. State and local water departments and county water resource authorities dominate the issuing bodies, with water treatment plants, filter plants, clearwell storage systems, and raw water equalization tanks as primary points of deployment. The scope spans both routine annual supply contracts for smaller components (saddles, couplings, clamps, and mixed valve types) and capital replacement projects for large specialized equipment rated to AWWA standards and NSF/ANSI 61 certification for potable water service.

Recent activity concentrates in Georgia, where Gwinnett County Department of Water Resources and the City of Marietta have issued multiple solicitations since late June 2026. Gwinnett County has posted competitive sealed bids for butterfly valves serving the Lanier and Shoal Creek Filter Plants (BL126-26, due September 23, 2026, ITB), quick insertion valves for pressurized and non-pressurized pipeline systems (2026-034-ITB, due August 27, 2026, multiyear contract), and resilient gate and tapping valves (IWQ 131155, due June 9, 2026, informal written quotation). Marietta issued an annual contract bid for water service saddles, couplings, clamps, and ball valves (BL121-26, due September 22, 2026, IFB). Outside Georgia, Alameda County Water District (California) solicited detector check valves (IFB 26/27-01, due July 14, 2026), and Palm Beach County (Florida) requested a one-time quotation for a Wilkins OEM reduced pressure principle backflow assembly (RFQ680260197JS2, due August 25, 2026). Gwinnett County maintains an ineligible source list that restricts participation; most solicitations require three project references, compliance with AWWA standards, and delivery on an F.O.B. Destination, freight-prepaid basis.
