UNSPSC 24111829: Excess flow valve

An excess flow valve is a spring loaded check valve which will close only when the flow of liquid or vapor through the valve generates sufficient flow or force to overcome the power of the spring holding it open.

UNSPSC 24111829 Excess flow valve is a Commodity code that captures industrial gas equipment rental, delivery, and refill services—specifically CO2 tank systems serving public facilities—rather than the valve components the code name suggests. State and local governments procure monthly rental of multi-size CO2 tanks (ranging from 125 to 750 cubic feet), associated delivery and refill services measured in pounds of gas per annum, maintenance and installation support, and tank removal and decontamination work. The issuing bodies include county facilities management divisions and city fire departments, with counties representing the dominant buyer segment for recurring gas supply contracts and cities occasionally soliciting specialized tank removal and environmental remediation services tied to aging infrastructure replacement.

Collier County, Florida dominates recent activity under this code, with two CO2 rental and refill solicitations posted within a four-month window: Quick Quote QQ2026144 (response due July 28, 2026) and QQ2026136 (response due June 24, 2026), both covering monthly rental of nine 750-cubic-foot and five 125-cubic-foot CO2 tanks across six county aquatic facilities, plus refill and delivery services for an estimated 100,000 pounds annually for rental tanks and 20,000 pounds annually for county-owned tanks at Big Corkscrew Island Regional Park, with prices firm through September 30, 2027. The City of Meriden, Connecticut posted an Invitation to Bid (ITB B027-12, response due September 9, 2026) for removal, decontamination, and disposal of a 4,000-gallon underground storage tank at Engine Company #2, including excavation, soil testing, contaminated water disposal, backfilling, and site restoration, requiring Connecticut state certification and a minimum two years of tank removal experience. Florida and Connecticut represent the geographic centers of recent code activity, with the contract types split between informal Quick Quote processes for recurring gas supply (county) and competitive bidding for one-time environmental remediation (municipal fire services).
