UNSPSC 31251511: Linear actuators

UNSPSC 31251511 Linear actuators, a Commodity code, covers motorized and hydraulic positioning devices that state and local governments procure primarily for water and wastewater treatment infrastructure—specifically flow control, gate operation, valve automation, and system integration at municipal treatment plants and distribution facilities. Recent solicitations show governments buying REXA proprietary hydraulic actuators with Flow Match Valve technology, Fisher-Rosem microprocessor-based positioners compatible with HART and fieldbus protocols, electric actuators from manufacturers including Asahi/America, Emerson, Flowserve, and Limitorque for modulating butterfly and slide gates, and pantograph subassemblies for transit equipment. State and local water utilities dominate the issuing-body mix—the City of Phoenix Water Services Department, City of Plant City Water Reclamation Facility, Seminole County wastewater treatment operations, and Gwinnett County water systems appear multiple times in recent procurements. Cities and counties conducting multi-year framework agreements or supplemental contracts for ongoing preventive and remedial maintenance dominate the activity; sole-source and Notice of Intent solicitations for REXA and Limitorque-brand equipment are common, reflecting infrastructure lock-in and proprietary technology justifications. School districts and transit authorities also buy limited volumes—Dallas Area Rapid Transit Authority recently solicited a pantograph actuator subassembly, and Mt. Hood Community College pursued advanced robotics platforms with integrated actuator systems for workforce training.

Recent activity concentrates in Florida, Texas, Arizona, Georgia, and Oregon. The City of Phoenix issued two separate electric actuator solicitations—IFB-26-0274 (March 23, 2026) for a five-year contract covering electric actuators, parts, valves, gearboxes, and software with authorized distributors from approved manufacturers, and IFB-26-0343 (June 5, 2026) as a supplemental procurement with delivery across multiple City water and wastewater treatment facilities and a contract term through February 28, 2031. Plant City's sole-source procurement (April 14, 2026, due date April 14) for REXA X3R10000-90-C-P actuator control systems valued at $29,580 illustrates the capital equipment nature of larger municipal upgrades, while Seminole County's sole-source intent (June 2, 2026) for REXA replacement parts and Gwinnett County's sealed-bid for four 108-inch slide gates (April 27, 2026, due May 1) show both component-level replacement and major system procurement running in parallel. The City of Austin (June 15, 2026, due June 16) and City of Waco's SCADA RFP (February 6 and March 12, 2026) reflect the integration of actuators within broader automation and controls environments. Multi-year framework agreements with pricing as percentage discounts from manufacturer list prices and firm-fixed pricing for Year One with annual adjustment provisions are standard contract structures.
