UNSPSC 31251511: Linear actuators

UNSPSC 31251511 Linear actuators is a Commodity code covering automated valve-control devices that state and local governments procure to regulate flow in water, wastewater, and reclaimed water systems. Recent solicitations show state and local buyers purchasing hydraulic and electric actuators as components of treatment-plant control systems, including proprietary branded systems (REXA, Limitorque) as well as multivendor electric actuators compliant with AWWA and NSF standards. The scope extends to actuator parts, replacement components, control panels, positioners, and associated repair and maintenance support. Issuing bodies soliciting under this code include municipal water and wastewater utilities (City of Austin, City of Phoenix, City of Plant City), county environmental service departments (Gwinnett County, Seminole County), and county-level wastewater treatment authorities in Florida. Water and wastewater utilities represent the consistent buyer population; no school districts, transit authorities, or state agencies appear in recent postings.
