UNSPSC 40141644: Rotary airlock valve

This valve is made up of a rotor with 6 rigid vanes that moves inside a round casing. The gap between the rotor vanes and the casing is further reduced by means of adjustable vane blades made of teflon or spring steel.

UNSPSC 40141644 Rotary airlock valve (Commodity) does not align with the work state and local governments are actually procuring under this code. The recent opportunities tagged with this commodity code describe water utility valve supply and repair services—backflow prevention devices, butterfly valves, resilient gate valves, quick insertion valves, valve actuators, and flow controllers for municipal water and wastewater systems—rather than rotary airlock valves, which are isolation and flow-control devices typically used in bulk solids handling and pneumatic conveying systems. The mismatch suggests either persistent miscoding in the source procurement databases or a narrow, unrelated use case that does not drive material activity in state and local purchasing under this UNSPSC designation.

Water utilities across Georgia, Florida, and Texas are the dominant issuing bodies, with Gwinnett County, the City of Tampa, the City of Lubbock, and the Douglasville-Douglas County Water and Sewer Authority accounting for multiple recent solicitations. The City of Tampa issued RFQ 26P00305 (sealed bids due June 22, 2026) for backflow prevention devices and fireline repair parts on an SLBE-exclusive basis, estimated at $75,000, requiring two items in stock at all times and delivery within 14 working days. Gwinnett County Board of Commissioners solicited sealed bids under ITB BL126-26 (due September 23, 2026) for large butterfly valves (54" to 108") for the Lanier and Shoal Creek Filter Plants, with a virtual pre-bid conference on September 2, 2026. The Douglasville-Douglas County Water and Sewer Authority requested sealed bids under IFB 327 (due October 7, 2026) for annual water and sewer pipe fittings and related inventory materials on an as-needed basis, with firm pricing for the one-year period December 20, 2026 through December 19, 2027. The City of Lubbock issued RFP 26-19705-YB (due July 23, 2026) for one electric valve actuator replacement conforming to EIM model MCAD-1 specifications (208 volts, three-phase AC, 1/4 HP) with remote control capability for the North Water Treatment Plant, evaluated on a 100-point scale emphasizing manufacturer qualifications, product performance, and warranty support.
