UNSPSC 40141658: Block and bleed valve

A heavy duty mainline valve made to hold bubble tight against high pressure. The valve is made with a small bleeder line and valve which are tapped into the block valve's bonnet. When the block valve is closed, its effectiveness may be checked by opening the bleeder valve for evidence of any leakage from the upstream or high-pressure side.

UNSPSC 40141658 Block and bleed valve (Commodity) covers replacement and spare parts for water and wastewater treatment operations, where state and local governments purchase both original equipment manufacturer components and competitive alternatives to service installed systems. Recent solicitations show concrete demand for electric valve actuators, butterfly valves, check valves, insertion valves, and specialized actuator parts from water treatment facilities and wastewater plants—often procured on as-needed or inventory-replenishment bases with firm pricing and same-day to two-week delivery requirements. The issuing-body mix spans city water and wastewater departments (Lubbock, Tampa, Austin, Dallas, Fort Worth, North Miami Beach), county water resources agencies (Gwinnett County, Hillsborough County, Wayne County), utility authorities (Eastern Municipal Water District, Douglasville-Douglas County Water and Sewer Authority), and regional cooperative purchasing vehicles (Sourcewell). Several recent opportunities involve sole-source and single-source awards to authorized OEM distributors (Flotech for Limitorque, Fluid Control Specialties for DeZurik, Illinois Tool Works for E.H. Wachs power valve operators), reflecting the proprietary nature of many valve systems installed in municipal infrastructure.

Recent activity concentrates in Texas, Florida, and Georgia, with secondary activity in California and Washington. Representative solicitations include the City of Lubbock RFP 26-19705-YB for electric valve actuator replacement and remote control station (due July 23, 2026) specifying EIM or Rotork equipment with technical performance and past-performance evaluation; City of Tampa RFQ for Anderson Greenwood wastewater parts (due July 24, 2026) requiring five-business-day delivery; Gwinnett County invitation for replacement check valves for the F. Wayne Hill Water Resources Center (due April 24, 2026) with approved manufacturers including DeZurik, Pratt, Crispin, and Val-matic; and Hillsborough County ITB 26-00122 for Hydra-Stop Insta-Valve 250 Patriot insertion valves (due February 18, 2026) with a $175,000 estimated budget. Competitive opportunities appear regularly alongside sole-source awards, with evaluation typically weighted toward lowest responsive bid, manufacturer qualifications, past performance, and warranty coverage.
