UNSPSC 31251509: Electromagnetic actuators

UNSPSC 31251509 Electromagnetic actuators, a Commodity code, covers motorized control devices that state and local governments procure for water treatment, wastewater operations, and infrastructure control systems — predominantly electromagnetic and hydraulic actuators that automate valve, gate, and flow-control operations across municipal utilities. Recent solicitations show procurement focused on electric actuators for municipal water and wastewater treatment plants, microprocessor-based positioners for automated control systems, and proprietary hydraulic actuators (particularly REXA-brand systems) for process automation and equipment standardization. State and local water utilities dominate the buying pattern, with a secondary market among transit authorities and specialized treatment facilities. The City of Phoenix Water Services Department appears most active, issuing overlapping solicitations for electric actuators and related parts to support five-year and four-and-a-half-year framework agreements. Additional repeat buyers include Seminole County, Florida (wastewater actuator parts via sole-source procurement) and the City of Plant City, Florida (REXA actuator system installation). Issuing bodies span large metropolitan utilities, county wastewater treatment operations, and municipal water reclamation facilities; transit authorities (Dallas Area Rapid Transit Authority) and special-purpose districts also participate.

Activity concentrates in Arizona, Florida, Texas, and Georgia, with secondary presence in Oregon and other jurisdictions. Recent representative opportunities include the City of Phoenix Water Services Department IFB-26-0343 and IFB-26-0274, both competitive sealed-bid solicitations for electric actuators, parts, valves, and gearboxes with response dates in June 2026 and April 2026 respectively, requiring compliance with AWWA C542, NSF/ANSI standards, IEEE 841, and NEMA certifications, and firm pricing for initial one-year periods with allowance for documented price increases thereafter. The City of Austin Purchasing Office issued IFQ 1100 BAS1093 on June 15, 2026, for two units of a Fisher Rosem DVC 6200 microprocessor-based positioner compatible with HART, FOUNDATION fieldbus, and PROFIBUS protocols, with quote submission due June 16, 2026. Seminole County pursued sole-source procurement of REXA actuator replacement and repair parts through PRO-CO, Inc. (Winter Springs, Florida) with vendor response due June 1, 2026, citing REXA's proprietary Flow Match Valve technology and 30+ year track record; the City of Plant City, Florida similarly issued a sole-source notice (IFB 26-038UM-NOI) for REXA actuators through TSC Jacobs with estimated procurement value of $29,580.00. Dallas Area Rapid Transit Authority solicited bids for an Actuator Subassembly Pantograph (Part Number 2098909) through BONFIRE with deadline April 28, 2026.
