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

NIGP 81573, Valves, Directional Control (To Control Pneumatic, Hydraulic, Or Water Cylinders), is an Item code under which state and local governments procure replacement parts, repair services, and maintenance support for actuators and control valves installed in water treatment, wastewater, and utility infrastructure. Recent solicitations show that state and local agencies buy OEM replacement parts for proprietary valve systems (Limitorque, REXA, E.H. Wachs power valve operators), off-site and field repair services, and maintenance support for directional-control equipment embedded in potable water, wastewater, and irrigation systems. Issuing bodies include city utilities departments, county water and wastewater authorities, and municipal water treatment facilities. The Orlando and Orange County, Florida combined procurement for Aquatech Parts and Services; the Tampa Water Production Department's Limitorque valve and actuator maintenance and parts supply; Collier County's power valve operator and maintenance procurement for Water, Wastewater, and IQ vehicles; and Seminole County's REXA actuator parts solicitation all demonstrate that municipalities and counties rely on sole-source and single-source designations for these procurements, typically justified by OEM exclusivity, proprietary technology, or manufacturer authorization requirements.

Geographic activity concentrates in Florida, where four of the five most recent solicitations originated (City of Orlando with Orange County, City of Tampa, Collier County, and Seminole County), with additional recent activity in Georgia (City of Atlanta Department of Watershed Management) and Texas (City of Southlake). The City of Tampa issued a sole-source notice to Flotech, Inc. for Limitorque valves and actuators with an estimated annual cost of $75,000 and a contract term through July 1, 2027 (Procurement 26-X-01439, due July 13, 2026). The City of Orlando posted a sole-source notice for Aquatech Parts and Services under S26-0592 with responses due October 6, 2026 at 5:00 p.m. ET, with Pats Pump and Blower identified as the exclusive source; challenges to the sole-source designation must be submitted through OpenGov within the seven-calendar-day posting period. Seminole County solicited REXA actuator replacement and repair parts through PRO-CO, Inc. (Solicitation SS5253, due June 1, 2026 at 5:00 p.m.), with the technical justification resting on REXA's proprietary Flow Match Valve technology and custom-engineered manufacturing. Collier County issued a Notice of Intent to Single Source Illinois Tool Works dba E.H. Wachs for power valve operators and maintenance services (PUR16720, contest deadline July 20, 2026 at 3:00 p.m.), with a proposed three-year term October 1, 2026 through September 30, 2029.
