UNSPSC 39122311: Pressure relay

A relay that operates in response to the magnitude of pressure and is being operated by using increase in pressure of insulation medium in the event of electrical or mechanical accidents as well as being used in protection of devices insulated with fluid.

UNSPSC 39122311 Pressure relay is a Commodity code that encompasses pressure sensing and control devices used in industrial and municipal water, electrical, and facility infrastructure projects. State and local procurement under this code centers on pressure relay components and assemblies for water treatment, electrical switchgear systems, generator control, and motor soft-starter installations—equipment typically purchased as part of larger capital upgrades or O&M contracts rather than as standalone commodity purchases. Recent opportunities show pressure relays integrated into control system projects rather than solicited in isolation, which reflects how state and local buyers typically acquire these components as subassemblies of control panels, motor control centers, or system modernization efforts.

The issuing bodies span water districts, counties, school districts, and municipalities across Texas, California, Florida, and Oregon. Eastern Municipal Water District (Riverside County, California) solicited pressure relay functionality as part of a medium voltage soft starter installation at Auld Road Booster Station (RFP with May 9, 2026 deadline); Orange County, Florida issued an IFB for electrical and mechanical upgrades at Eastern Water Reclamation Facility (Y26-604, due April 30, 2026) encompassing switchgear and control relay replacements; West Basin Municipal Water District (California) procured motor control center replacement including protective relay components (RFB RFBTH0120, due March 31, 2026); and the City of Santa Fe (New Mexico) sought PLC and SCADA system modifications with Schneider Electric control components (RFP FY26-RFP-036). Hillsborough County Water Resources Department purchased mercury float switches (ITB ITB-26-00123 and ITB-26-00138) for pump control in wells and lift stations, with estimated values of $184,000 and $60,000 over two-year terms. Activity is concentrated in water utility infrastructure upgrades and electrical system modernization, with limited direct commodity-level procurement of pressure relays as standalone items in recent notices.
