Quick Summary
The Department of the Navy, specifically NAVSUP Weapon Systems Support Mechanicsburg, is soliciting proposals for STEM, FLUID VALVE components. This procurement is for crucial shipboard systems, requiring Special Emphasis Material with stringent quality and traceability standards. This is a Total Small Business Set-Aside. Proposals are due by August 24, 2026.
Scope of Work
The requirement is for the manufacture and supply of stems for 4-inch combination hull and backup ball valves, in accordance with NAVSEA drawing 801-6404584. Key material specifications include QQ-N-286, Form 2, Annealed and Age Hardened, with specific testing for annealing, age hardening, and ultrasonic inspection. Welding on QQ-N-286 material is prohibited. Contractors must utilize approved laboratories for Slow Strain Rate Tensile Tests and adhere to detailed inspection criteria for O-ring grooves and sealing surfaces. Configuration control, including procedures for Waivers/Deviations and Engineering Change Proposals (ECPs), is mandatory. The use of mercury or mercury-containing compounds is strictly prohibited.
Quality Assurance & Traceability
This opportunity involves Special Emphasis Material, necessitating a comprehensive Certificate of Compliance. Contractors must maintain a quality system compliant with ISO-9001, ISO-10012 or ANSI-Z540.3 with ISO-17025 (or MIL-I-45208). Government Quality Assurance (GQA) will be performed at the source, including potential inspections at subcontractor facilities. Traceability is paramount, requiring unique identification numbers and material markings (per MIL-STD-792) from raw material to the final product. Quantitative chemical and mechanical analysis is required, with re-certification if material properties are altered. Electronic signatures on certifications are acceptable under controlled conditions. Comprehensive receiving, in-process, and final inspections, including 100% inspection of material verification data and traceability markings, are required.
Contract Details & Submission
This is a Solicitation under a Total Small Business Set-Aside. Final material delivery is required within 365 days after the contract's effective date, with certification data CDRLs due 20 days prior to delivery. Past performance will be a key evaluation factor (FAR 13.106(a)(2) and DFARS 252.213-7000). Only offerors with an acceptable Quality Control Manual are eligible for award. Certification data must be submitted via Wide Area Work Flow (WAWF) to Portsmouth Naval Shipyard (Ship to N50286, Inspect by N39040, Accept by N39040), with email notification to PORT_PTNH_WAWF_Notification@navy.mil. No material may be shipped prior to acceptance. The response deadline is August 24, 2026. For inquiries, contact JORDAN.D.NEELY2.CIV@US.NAVY.MIL (717-605-8197).
