About this opportunity
The U.S. Army Corps of Engineers, Walla Walla District, seeks two new 18-inch carbon steel globe body silent check valves for Lower Granite Dam, with proposals due August 19, 2026 at 2:00 PM PDT (extended from August 13 via Amendment 0001 issued August 14 to allow time for technical question resolution). The procurement is a 100% Women-Owned Small Business set-aside.
Place of performance is Pomeroy, Washington. Valves must be designed to prevent flow reversal, surge, and water hammer, complying with all applicable ASTM codes and standards. Technical specifications mandate a cast carbon steel body (ASTM A216 Grade WCB), 316 stainless steel trim/disc (ASTM A351 Grade CF8M), 302 stainless steel spring (ASTM A276), and stainless steel guide pins and bushings. Operational parameters require a minimum 285 PSI at 100°F pressure/temperature rating, ANSI Class 150 integrally cast flanged ends with 16-hole bolt pattern, flow capacity of at least 110% of equivalent pipe size, cracking pressure less than 1 PSI, and top-and-bottom guided disc alignment. Physical dimensions are mandatory with no exceptions: face-to-face of exactly 22.5 inches, overall diameter not exceeding 31 inches, weight not exceeding 1,300 lbs, and Class 150 flanges per ASTM A105 and ASME B16.5 (25-inch OD, 22.75-inch bolt circle diameter, 16-hole configuration). Valves must feature metal-to-metal hand-lapped drop-tight seal and permanent corrosion-resistant stainless steel nameplate.
Delivery is required within 22 weeks from contract award, FOB destination with contractor responsible for transportation. Quotes must be firm-fixed-price for new equipment only; remanufactured, refurbished, or gray market items are unacceptable.
