NIGP 81584: Valves, Temperature and Pressure Regulating

NIGP 81584 Valves, Temperature And Pressure Regulating, an Item code, encompasses pressure and temperature transmitters, gauges, switches, thermowells, diaphragm seals, and related instrumentation accessories that state and local water and wastewater utilities procure for process monitoring, control, and compliance at treatment facilities and distribution/collection systems. Recent solicitations show municipalities and county water authorities buying these products as critical components of SCADA systems integration, with vendors required to stock inventory locally and fulfill replacement parts on same-day or next-business-day notice. Issuing bodies under this code include city water departments, county water and wastewater divisions, and other municipal utilities operating treatment and conveyance infrastructure; these are repeat, high-frequency buyers managing aging distribution networks and regulatory compliance requirements.
