UNSPSC 23153404: Assembly systems for chassis vehicle operation VO

UNSPSC 23153404 Assembly systems for chassis vehicle operation VO, a Commodity code, describes equipment assemblies that regulate and measure fluid flow in water treatment operations — specifically venturi-type flow controllers paired with butterfly valves designed for potable water applications in municipal utilities. State and local governments procure these assemblies as drop-in replacements for worn or obsolete water treatment infrastructure, with vendors supplying factory-tested, pre-assembled units that meet drinking-water standards and fit into existing mechanical and electrical mounting points. The issuing bodies pursuing this code are municipal water utilities; in the recent record, the City of Lubbock, Texas, is the sole identified buyer.

The City of Lubbock, Texas, posted an Invitation to Bid (ITB 26-19653-YB) on May 12, 2026, for a replacement rate of flow controller and 16-inch butterfly valve assembly for the North Water Treatment Plant, with a sealed-bid deadline of May 27, 2026, at 3:00 p.m. The equipment must deliver a flow range of 0–144 inches water column, conform to AWWA C504 standards and ASTM A536 Grade 65-45-12 cast iron construction with Type 316 stainless steel throat liner and NSF 61–approved epoxy coating, and fit within 46.5 inches of available space; factory assembly and testing to 0.5 percent accuracy are required. The City offers a local bidder preference of up to five percent for contracts under $500,000 and requires vendor certifications including suspension and debarment status, Iran sanctions compliance, Israel boycott compliance, most-favored pricing, and cybersecurity and personally identifiable information risk assessment disclosures; a non-mandatory pre-bid site visit is scheduled for May 20, 2026. No budget or award value is listed.
