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 is a Commodity code that covers industrial valve components and replacement parts for municipal water, wastewater, and utility system operations. State and local governments procure these valves as components within treatment facility infrastructure, primarily through water departments, wastewater authorities, and county utility systems managing potable water, reclaimed water, and process systems. Recent solicitations show purchasing activity concentrated in equipment replacements and spare-parts inventory replenishment for operational continuity at treatment plants and pumping stations, with vendors competing on technical compliance to OEM specifications, lead times, warranty terms, and total cost of ownership including installation support and documentation.

Issuing bodies include city water and wastewater departments, county utility authorities, special-purpose districts, and regional water treatment facilities across multiple states. The City of Lubbock, Texas; City of Tampa, Florida; Gwinnett County, Georgia; Hillsborough County, Florida; and Seminole County, Florida appear repeatedly in recent postings. Geographic activity concentrates in Texas, Florida, and Georgia, with secondary posting activity in California and other states. Representative recent opportunities include the City of Lubbock's RFP 26-19705-YB (posted July 14, 2026, due July 23, 2026) for an electric valve actuator replacement conforming to EIM model MCAD-1 specifications with remote control capability for the North Water Treatment Plant, evaluated on a 100-point scale weighting manufacturer qualifications (30 points), product technical performance (30 points), past performance (20 points), and reliability/warranty/service support (15 points); the City of Tampa's RFQ for Anderson Greenwood parts (posted July 13, 2026, due July 24, 2026) for soft-good kits and retainer plates for the Wastewater Department with five-business-day delivery required; and Hillsborough County's intent to single-source Limitorque valves and actuators to Flotech, Inc. (posted July 8, 2026) for replacement parts and off-site repair at the David L. Tippin Water Treatment Facility with an estimated annual cost of $75,000 and term through July 1, 2027. Single-source and sole-source procurements are common when OEM parts or exclusive distributor relationships govern the market, as demonstrated by Flotech's exclusive Flowserve-Limitorque authorization and PRO-CO's REXA actuator distributorship.
