UNSPSC 31251515: Actuator kit

Collection of components within a single package and with a single catalog number used to assemble a modular switch.

UNSPSC 31251515 Actuator kit (Commodity) encompasses electric and hydraulic actuators and actuator subassemblies that state and local water and wastewater utilities procure to control flow, pressure, and valve positioning in treatment plants, distribution systems, and pump stations. Recent solicitations show municipalities buying positioners, electric actuators with integrated control systems, actuator parts and repair kits, and branded actuator assemblies from vendors such as REXA, Limitorque, and Flowserve. The issuing bodies are predominantly municipal water and wastewater departments and county utilities, with secondary activity from transit authorities and special-purpose districts. Competitive procurement dominates the market, though sole-source and manufacturer-exclusive procurements are common when existing equipment infrastructure locks buyers to proprietary brands or when evaluations conclude that alternative suppliers cannot deliver compatible parts without disrupting critical treatment operations.

Recent activity concentrates in Texas, Florida, Arizona, Georgia, and Oregon. The City of Phoenix Water Services Department has issued at least two competitive IFBs for electric actuators, parts, valves, and gearboxes over multiple years (IFB-26-0274, posted March 23, 2026, due April 2; and IFB-26-0343, posted June 5, 2026, due June 4), seeking five- to four-and-one-half-year supply contracts with approved manufacturers including Asahi/America, Emerson, Rexa, and US Koei Technologies. The City of Austin Purchasing Office solicited two units of a Fisher Rosemount DVC 6200 positioner under IFQ 1100 BAS1093 (due June 16, 2026), specifying HART and PROFIBUS communications. Sole-source and brand-preference procurements include Seminole County, Florida pursuing REXA actuator parts through PRO-CO (SS5253, due June 1, 2026) and the City of Plant City, Florida executing a $29,580 sole-source for REXA actuator and control systems through TSC Jacobs (IFB 26-038UM-NOI, due April 14, 2026). The Dallas Area Rapid Transit Authority (DART) procured an Actuator Subassembly Pantograph (part 2098909) under standard PO terms (due April 28, 2026). Gwinnett County, Georgia solicited 108-inch slide gates for the Lanier Filter Plant (BL044-26, due May 1, 2026), a peripheral but related control application. A Florida county RFI on Limitorque-brand actuators (OPN2132136F1, due May 20, 2026) sought information on alternative suppliers to incumbent Flowtech Inc., indicating periodic challenges to sole-source designations when maintenance and parts costs rise.
