UNSPSC 31251500: Actuators

UNSPSC 31251500 Actuators, a Class code, encompasses the supply and replacement of electric, pneumatic, and flow-control valve actuators and related control equipment for water and wastewater treatment infrastructure. State and local governments procure these components for new treatment plant construction, routine equipment maintenance, and system upgrades at municipal water treatment plants, wastewater facilities, and water distribution networks. Recent solicitations show concrete demand for electric valve actuator replacement units with remote control stations, Flowserve Limitorque actuators and replacement parts, power valve operators for field service vehicles, and dual check valve replacement services on an as-needed basis. Water utilities and treatment authorities are the dominant issuing bodies, supplemented by county water departments, municipal utilities, and regional water authorities that collectively source actuators either as standalone equipment purchases or as components within broader valve replacement and piping modernization projects.

Activity concentrates in water and wastewater service providers across Texas, Florida, Maryland, Virginia, Georgia, South Carolina, and California. Representative recent opportunities include the City of Lubbock, Texas RFP 26-19705-YB for one replacement EIM model MCAD-1 electric valve actuator with remote control station for the North Water Treatment Plant, due July 23, 2026; Tampa Bay Water's Notice of Intent to Sole Source procurement of Flowserve Limitorque actuators and replacement parts and service from Valve & Actuation Services dba Chalmers & Kubeck South, objections due July 30, 2026; Collier County, Florida's Notice of Intent to Single Source Illinois Tool Works dba E.H.
