NIGP 81573: Valves, Directional Control (to Control Pneumatic, Hydraulic, or Water Cylinders)

NIGP 81573 Valves, Directional Control (To Control Pneumatic, Hydraulic, Or Water Cylinders), an Item code, covers replacement parts, repair services, and OEM-standard actuator and valve equipment for water, wastewater, and utility infrastructure. State and local governments buy under this code primarily directional control valves, proprietary actuator components, and manufacturer-authorized maintenance and repair services for treatment plants, pump stations, vehicle-mounted utility equipment, and pressurized piping systems. Issuing bodies include municipal water departments, county water authorities, utility districts, and city departments of public works and watershed management. Florida municipalities and districts appear in multiple recent solicitations, though the geographic spread extends to California and Georgia water agencies. Most activity follows sole-source or single-source procurement paths justified by OEM compatibility requirements, proprietary technology (such as REXA's Flow Match Valve), manufacturer authorization restrictions, and installed-base lock-in.

Recent opportunities illustrate the scope: the City of Tampa issued an intent to single-source Limitorque valves, actuators, and off-site repair services to Flotech, Inc. (estimated annual cost $75,000, notice period ending July 13, 2026) under a sole-source IFB path; Collier County, Florida posted a Notice of Intent to Single Source Illinois Tool Works dba E.H. Wachs for power valve operators and valve equipment maintenance services on water and wastewater vehicles (three-year proposed term October 1, 2026 through September 30, 2029, contest deadline July 20, 2026); and Seminole County, Florida pursued a sole-source procurement of REXA actuator replacement and repair parts for wastewater treatment plants through PRO-CO, Inc., citing proprietary Flow Match Valve technology and incompatibility with alternative manufacturers (Auma, Rotork, Limitork). The City of Bradenton also solicited insertion valve and line stop services for potable water and sewer force mains ranging 2 to 12 inches (ITB deadline January 9, 2026). Competitive activity exists but remains limited; sole-source and single-source designations dominate due to OEM part requirements and manufacturer-authorization exclusivity.
