UNSPSC 40141630: Piston check valves

UNSPSC 40141630 Piston check valves (Commodity) covers check, gate, butterfly, and ball valves—including specialized components such as quick insertion valves, resilient wedge insert gate valves, tapping sleeves, and vacuum relief and air release valves—that state and local water utilities procure for distribution systems, treatment plants, and water main installations. Recent solicitations show municipalities and counties buying these valves as replacement equipment for existing infrastructure (filter plant clearwells, high-service pump stations, raw water equalization tanks), as components within larger water main relocation and replacement projects, and as stock items for routine maintenance and emergency repairs. The issuing bodies are predominantly municipal water departments and county water resource authorities; the City of Tampa, Gwinnett County, DeKalb County, and the City of Marietta appear repeatedly across multiple solicitations in the second and third quarters of 2026. Sourcing is often restricted to authorized distributors or specific manufacturers—APCO, Watts, Ames, Wilkins, and Mueller appear as preferred or required vendors in recent bids—with many solicitations requiring compliance with AWWA Standards C504/C516, NSF/ANSI 61 certification for drinking water service, and American Iron and Steel or Buy American Act provisions where applicable.

Geographic activity concentrates in Georgia (Gwinnett County, DeKalb County, City of Marietta, City of Calhoun) and Florida (City of Tampa, City of Sarasota), with occasional notices from Washington state through Sourcewell cooperative purchasing. Recent representative opportunities include the City of Tampa Wastewater Department's Intent to Single Source for APCO Check, Vacuum Relief and Air Release Valves (27X00022, due October 14, 2026); the City of Tampa Water Department's bid solicitation for backflow prevention devices and fireline repair parts under SLBE set-aside (26P00305, IFB, estimated contract value $75,000, due June 22, 2026); Gwinnett County's competitive sealed bid for double offset butterfly valves in multiple sizes for Lanier and Shoal Creek Filter Plants (BL126-26, ITB, due September 23, 2026, with virtual pre-bid conference September 2, 2026); and DeKalb County's multiyear contract ITB for quick insertion valves, tapping sleeves, and resilient wedge insert gate valves (2026-034-ITB, due August 27, 2026). Delivery, stock-maintenance, warranty, and manufacturer documentation requirements are standard across these procurements; many contracts run one to three years with optional renewals or extension periods.
