UNSPSC 31251516: Switch actuator

Actuator arms in various configurations used with modular switch bases to build a complete switch assembly.

UNSPSC 31251516 Switch actuator is a Commodity code covering electromechanical and hydraulic actuators and actuator subassemblies purchased by state and local water utilities, wastewater treatment authorities, and transit systems to control flow, pressure, and positioning in critical infrastructure operations. State and local buyers procure replacement actuators, control systems, parts, and repair services for municipal water treatment, wastewater processing, stormwater management, and transit vehicle applications, typically specifying compatibility with existing equipment and industry standards such as AWWA C542, NSF/ANSI 61 and 372, IEEE 841, and NEMA ratings. Issuing bodies include municipal water and wastewater departments (City of Phoenix Water Services, City of Austin, City of Plant City), county utility authorities (Seminole County), and transit agencies (Dallas Area Rapid Transit Authority). Recent solicitations show heavy reliance on proprietary or brand-locked equipment, with multiple jurisdictions pursuing sole-source procurements of REXA actuators and Limitorque-brand actuators rather than competitive bidding.

Geographic activity clusters in Texas, Arizona, and Florida, with recent opportunities also in Georgia and Oregon. The City of Phoenix Water Services Department issued two solicitations within two months (IFB-26-0274 in March 2026 and IFB-26-0343 in June 2026) for five- and four-and-a-half-year electric actuator supply contracts covering multiple water and wastewater treatment facilities across the Phoenix metropolitan area, specifying authorized distributors of manufacturers including Asahi/America, Badger Meter, Emerson, Flowserve, Rexa, and US Koei Technologies. The City of Austin Purchasing Office solicited two units of a Fisher Rosem DVC 6200 microprocessor-based positioner (IFQ 1100 BAS1093, due June 16, 2026) for delivery to Austin Energy-Sand Hill Energy Center. Seminole County, Florida pursued sole-source procurement of REXA actuator replacement and repair parts for wastewater treatment plants through PRO-CO, Inc. (due June 1, 2026), and the City of Plant City, Florida issued a Notice of Intent to Sole Source REXA actuators through TSC Jacobs with an estimated system cost of $29,580.00 (response due April 14, 2026). The State of Florida (through a county jurisdiction) issued an RFI on Limitorque-brand actuators (due May 20, 2026) to determine whether alternative vendors exist for products currently sourced exclusively from Flowtech Inc. The Dallas Area Rapid Transit Authority solicited bids for an Actuator Subassembly Pantograph (due April 28, 2026) and Gwinnett County, Georgia issued a competitive sealed bid for four replacement 108-inch slide gates with electrical operators for the Lanier Filter Plant (due April 22, 2026), both requiring FOB Destination delivery and compliance with AWWA standards.
