48--VALVE,BALL

The contract concerns the procurement of a 6-inch ball valve and associated components for critical shipboard systems, with stringent quality and traceability requirements due to the high-risk nature of potential failures. The item is designated as SPECIAL EMPHASIS Level I material, requiring full compliance with multiple military and industry specifications, including ASTM, MIL-STD, QQ-N, and SAE standards for materials like UNS C96400, QQ-N-286, ASTM-B505, and SAE-AMS-6931. All materials must be traceable from raw stock to finished component via unique heat-lot or batch markings, with chemical and mechanical certifications verified at every stage of production. Radiography, ultrasonic inspection, liquid penetrant testing, and pressure verification are mandatory for specific parts, with all test results documented and submitted for government review. The contractor must maintain ISO-9001 or MIL-I-45208 quality systems, conduct 100% inspection of certification data and traceability markings, and ensure all welding, brazing, and coating processes adhere to approved procedures and documented qualifications. Delivery is governed by a detailed schedule: radiographic shooting sketches are due 45 days after contract award, production radiography 135 days after RSS approval, and final delivery must occur no later than 250 days after contract effective date. Certification data must be submitted 20 days prior to delivery, and all items require a formal Certificate of Compliance affirming complete conformance with all contract requirements. Fasteners and critical components must be permanently marked per MIL-STD-792 with manufacturer ID, material symbol, and traceability numbers, with specific rules for Teflon-coated balls, self-locking nuts, and seats. The contract mandates use of the WAWF system for payment and requires all proposals to be submitted via email to the designated point of contact by 4:00 PM EST on July 14, 2026. The solicitation is a firm-fixed-price, total small business set-aside, requires facility clearance for classified drawings, and is certified as a DO-priority order under the Defense Priorities and Allocations System. All technical data, drawings, and supporting documentation are accessible exclusively via the ECDS portal, and deviations or waivers must be formally submitted through that system for government approval.
