UNSPSC 31251507: Rotary actuators

UNSPSC 31251507 Rotary actuators is a Commodity code covering microprocessor-based positioners, electric actuators, and hydraulic actuator systems that state and local governments procure for control and operation of valves, gates, and flow-diversion equipment in water, wastewater, and utility infrastructure. Recent solicitations show cities and counties purchasing actuators as standalone positioners, multi-year supply contracts with parts and accessories, and integrated control systems for treatment-plant automation. The code spans both electric actuators (commonly specified for municipal water and wastewater treatment) and proprietary hydraulic systems (such as REXA Flow Match Valve technology for balanced fluid transfer without makeup reservoirs). Issuing bodies include municipal water and wastewater utilities, county treatment authorities, transit agencies, and regional water districts; the City of Phoenix Water Services Department has posted multiple competitive procurements for electric actuators in the past four months, signaling sustained municipal demand. Water utility customers predominate, with recurring solicitations for actuator supply, preventive maintenance, emergency repair parts, and technical support spanning four- to five-year contract terms.

Recent activity concentrates in Arizona, Florida, Georgia, and Texas. The City of Phoenix Water Services Department issued competitive sealed bids (IFB-26-0274, posted March 23, 2026, due April 2) and a supplemental procurement (IFB-26-0343, posted June 5, 2026, due June 4) for electric actuators, parts, valves, and gearboxes from authorized distributors of Asahi/America, Auma, Badger Meter, Beck, Emerson, Flowserve, Rexa, and US Koei Technologies, both for five-year contracts commencing May 1, 2026.
