UNSPSC 41112404: Pressure regulator

UNSPSC 41112404 Pressure regulator, a Commodity code, covers pressure measurement and control devices—pressure gauges, transmitters, switches, and related instrumentation—that state and local water, wastewater, and waste-to-energy systems deploy for process monitoring, safety compliance, and SCADA integration. Recent solicitations show state and local buyers sourcing pressure gauges, pressure transmitters, pressure switches, diaphragm seals, and associated instrumentation for municipal water and wastewater treatment facilities, lift stations, and industrial process applications. Cities and county water authorities are the primary issuing bodies, with purchases often bundled into multi-year standing inventory or replacement-parts contracts and routed through authorized distributors of established vendors such as Siemens, Allen Bradley, Ashcroft, WIKA, Honeywell, and Emerson. The code also encompasses integrated process instrumentation suites where pressure regulators and transmitters function as components of broader SCADA system architectures and atmospheric monitoring installations at critical infrastructure sites.

Recent activity concentrates in Florida and Arizona. The City of Tampa has posted multiple solicitations including an Intent to Single Source for Allen Bradley and Rockwell Automation repair parts and support (ISS 27X00020, objection deadline October 14, 2026), an RFQ for inventory gauges with quantities of two to four units per line item covering chlorine gauges and gauge guards (RFQ 26P00548, due October 6, 2026), and a sheltered SLBE-only invitation for bid on wastewater panel and switch inventory including pressure switches (ITB 26P00425, bids due August 6, 2026). The City of Phoenix Water Services Department issued a five-year IFB for pressure and temperature instrumentation equipment with approved manufacturers including ABB, Ashcroft, Dwyer, Emerson, Honeywell, Siemens, and VEGA (IFB 26-0398, sealed offers due August 18, 2026), and a separate five-year IFB for atmospheric monitoring instruments-fixed at water and wastewater facilities with pressure-based gas detection equipment (IFB-27-0435, sealed offers due September 4, 2026). Collier County, Florida pursued a three-year single-source contract with Gilson Engineering Sales for Siemens process instrumentation including pressure and temperature transmitters (PUR17875, challenge period closed October 1, 2026). The City of Gallup, New Mexico solicited SCADA system upgrades incorporating pressure and flow measurement instrumentation across 46 water system sites (RFP released November 21, 2025, proposals due December 11, 2025). Vendors must meet local stocking and same-day or next-business-day parts availability requirements, provide professional references and minimum contract history, and comply with DBE and small business participation plans where applicable.
