A Valve interlocking system locking devices guides the operator through a predefined sequence with unique keys for each step. Each valve interlock is supplied with two keys, one for the locked-open position and one for the locked-closed position.

UNSPSC 40141662 Valve interlock system (Commodity) encompasses water distribution and treatment valve components—including butterfly valves, quick insertion valves, resilient gate valves, detector check valves, ball valves, and backflow assemblies—that state and local water utilities procure for infrastructure maintenance and system upgrade. The issuing bodies are primarily county and municipal water departments and boards of commissioners managing water treatment facilities, filter plants, and distribution networks. The work solicited ranges from commodity purchases of standard valve components under annual supply contracts to specialized equipment buys tied to specific treatment-plant modernization projects, with responses structured as competitive sealed bids, requests for quotation, or invitations to bid.

Georgia water authorities dominate recent activity: Gwinnett County Department of Water Resources has posted multiple opportunities for butterfly valves, resilient gate valves, quick insertion valves, and slide gates between April and August 2026, while the City of Marietta, Georgia solicited water service saddles, couplings, clamps, and valves (due September 22, 2026) under annual contract BL121-26. Outside Georgia, Palm Beach County Board of County Commissioners issued an RFQ for a reduced pressure principle backflow assembly OEM (due August 25, 2026), and Alameda County Water District in California posted an IFB for detector check valves (due July 14, 2026). Gwinnett County's BL126-26 invitation to bid for butterfly valves at two filter plants (due September 23, 2026) exemplifies the scope: double offset butterfly valves in sizes from 54 inches to 108 inches, with gearboxes and accessories, all meeting AWWA Standards C504/C516 and NSF/ANSI 61 certification. The County of DeKalb, Georgia issued a three-year multiyear contract ITB for quick insertion valves and tapping sleeves (due August 27, 2026). Water treatment plant purchases typically require pre-bid conferences, comprehensive operation and maintenance documentation, multiple project references, and F.O.B.
