UNSPSC 40141630: Piston check valves

UNSPSC 40141630 Piston check valves is a Commodity code. State and local water utilities are soliciting piston check valves and related backflow-prevention assemblies—including double-check detector assemblies, resilient check valves, and swing check valves—as components within larger water system maintenance, rehabilitation, and infrastructure projects. The code spans both materials-only procurements for water main replacement and as-needed supply agreements for valve stock and repair parts. Issuing bodies include municipal water departments (City of Sarasota, City of Tampa, City of Charlotte), county water resources divisions (Gwinnett County, Franklin County, Bryan County), special-purpose water districts (Alameda County Water District), and other municipal utilities. Gwinnett County, Georgia appears frequently as a repeat buyer, issuing multiple informal written quotations and competitive sealed bids for check valves, resilient-seat gates, and related valve assemblies across several calendar quarters.

Recent activity spans Florida, Georgia, California, North Carolina, and Texas. Representative recent procurements include the City of Sarasota's ITB #26-31JS for Small AC Water Main Replacement materials (posted June 29, 2026, due June 16, 2026)—a materials-only bid requiring conformance to an approved-products list with twelve-month warranty terms and ninety-day delivery; the City of Tampa's re-bid for Double Check Detector assemblies (posted June 24, 2026, due June 23, 2026) on an as-needed basis; Tampa's SLBE-exclusive bid for backflow prevention devices and fireline repair parts estimated at $75,000 (posted June 22, 2026, due June 22, 2026); and Gwinnett County's competitive sealed bid for 19 replacement swing check valves for the F.
