UNSPSC 23153405: Unlimited component assembly

UNSPSC 23153405 Unlimited component assembly, a Commodity code, covers factory-assembled flow control and valve components for water treatment infrastructure. State and local governments procure pre-assembled rate-of-flow controllers paired with butterfly valves designed to regulate and measure potable water flow in water treatment plants. These assemblies arrive factory-tested and ready for installation, with vendors responsible for precision engineering to AWWA and ASTM standards, materials certification for potable water service (including NSF 61 epoxy coatings and stainless steel internals), and delivery of operation and maintenance documentation. Cities and water utilities are the primary buyers under this code, though the source indicates the City of Lubbock extends contract eligibility to subordinate entities including independent school districts and county governments through interlocal purchasing agreements.

The City of Lubbock, Texas, posted an Invitation to Bid (ITB 26-19653-YB) on May 12, 2026, with a response deadline of May 27, 2026, seeking a replacement 16-inch venturi-type flow controller with a 0–144 inches water column range paired with an AWWA C504-compliant butterfly valve for the North Water Treatment Plant. The assembly must fit within a 46.5-inch space envelope and deliver accuracy within 0.5 percent of actual flow rate; the cast iron body must meet ASTM A536 Grade 65-45-12 specifications with Type 316 stainless steel throat liner and be compatible with the City's existing electric valve actuator mounting plate. Pricing is on an F.O.B. delivered basis with firm pricing for a minimum of sixty days; the City applies a local-vendor preference allowing local bidders within city limits to win if their bid is within five percent of the lowest non-resident bid on contracts under $500,000. A non-mandatory site visit was scheduled for May 20, 2026, and sealed bids were opened via teleconference.
