UNSPSC 40141621: Diaphragm valves

UNSPSC 40141621 Diaphragm valves (Commodity) encompasses water infrastructure replacement and service parts, though recent state and local procurement activity under this code emphasizes resilient gate valves, check valves, butterfly valves, and associated actuator components for municipal water treatment and wastewater systems rather than diaphragm valves specifically. Water districts and county departments of water resources represent the dominant issuing-body mix, with Gwinnett County, Georgia posting the majority of recent solicitations. Procurements range from informal written quotations (IWQ) for small-quantity valve purchases to sealed-bid competitions for larger replacement projects at treatment facilities. Vendors must typically hold manufacturer certifications, maintain current vendor registrations with the jurisdiction, and provide three or more references demonstrating prior experience with similar water infrastructure products.

Gwinnett County, Georgia dominates recent activity under this code, with five posted opportunities between January and June 2026 for Mueller resilient gate valves, RBX valve service kits, MJ resilient valves, and swing check valves for the F. Wayne Hill Water Resources Center and Lanier and Shoal Creek Filter Plants. The City of Phoenix Water Services Department issued an Invitation for Bid (IFB-26-0271) on March 26, 2026, for PVC/CPVC pipe, valves, and fittings on a five-year contract commencing June 1, 2026, requiring vendors to maintain local inventory and provide daily support. Seminole County, Florida pursued a sole-source procurement (SS5253) in June 2026 for REXA actuator replacement and repair parts for wastewater treatment plants through PRO-CO, Inc., citing proprietary Flow Match Valve technology and 30+ years of proven performance. Sourcewell, a Minnesota cooperative purchasing vehicle, advertised RFP #061626 on June 12, 2026, for law enforcement equipment available to participating entities across the United States and Canada, though this opportunity does not align with the water-infrastructure focus of other solicitations under the code.
