LLA CHECK VALVES

<p>This is a solicitation for commercial products, as supplemented with additional information included in this notice. The U.S. Government requires the purchase and delivery of two (2) new, 18-inch Carbon Steel Globe Body Silent Check Valves to Lower Granite Dam. Quotes must be submitted on a firm-fixed-price basis for new equipment only; remanufactured, refurbished, or &quot;gray market&quot; items will not be accepted. The supplied valves must be designed to prevent flow reversal, surge, and water hammer, complying with all applicable ASTM codes and standards.</p>

<p>Technical requirements include a Cast Carbon Steel body (ASTM A216 Grade WCB), 316 Stainless Steel trim/disc (ASTM A351 Grade CF8M), a 302 Stainless Steel spring (ASTM A276), and stainless steel guide pins and bushings. Operational parameters dictate a minimum pressure/temperature rating of 285 PSI at 100&deg;F, ANSI Class 150 integrally cast flanged ends with a 16-hole bolt pattern, a flow capacity of at least 110% of the equivalent pipe size, a cracking pressure of less than 1 PSI, and top-and-bottom guided disc alignment for multi-angle installation. Furthermore, the valves must feature a metal-to-metal hand-lapped drop-tight seal and a permanent corrosion-resistant stainless steel nameplate detailing the manufacturer, model, size, rating, and manufacturing date. Due to strict installation constraints, the following physical dimensions are mandatory with no exceptions allowed: a face-to-face measurement of exactly 22.5 inches, an overall diameter not exceeding 31 inches, a valve weight not exceeding 1,300 lbs, and Class 150 flanges meeting ASTM A105 and ASME B16.5 standards (25-inch outside diameter, 22.75-inch bolt circle diameter, and a 16-hole configuration).</p>
