Quick Summary
The Department of the Navy, NAVSUP Weapon Systems Support Mechanicsburg, is soliciting proposals for Valve Seats for a crucial shipboard system. This requirement is for Special Emphasis Material (Level I/SUBSAFE), demanding stringent quality and traceability. This is a Total Small Business Set-Aside. Proposals are due by April 1, 2026, at 4:30 PM Local Time.
Scope of Work
This solicitation is for the procurement of seats for 6 x 6 x 6 inch Ball Valves, manufactured according to Newport News Drawing 2285-298 piece 30. The material required is MC903 (Type 6 cast nylon) or an approved equal, which must meet specific quantitative chemical and mechanical properties, including melting point, relative viscosity, specific gravity, dimensional change, tensile impact, tensile yield stress, compressive strength, water absorption, and Rockwell "M" hardness. The material is designated as Special Emphasis Material due to its use in a critical shipboard system where failure could result in serious personnel injury, loss of life, or loss of vital shipboard assets.
Key Requirements
Offerors must establish and maintain a quality system compliant with ISO-9001, amplified by ISO-10012 or ANSI-Z540.3 with ISO-17025, or MIL-I-45208. Strict traceability and certification are mandatory, requiring unique traceability numbers, heat-lot numbers, or batch numbers marked on the material, linking directly to chemical and mechanical property certification data (Objective Quality Evidence - OQE). Government Source Inspection (GSI) will be performed, and suppliers of Level I/SUBSAFE material must submit documented quality system procedures. Configuration control, including waivers, deviations, and Engineering Change Proposals (ECPs), is critical and requires Government approval. All items must be mercury-free. Packaging must comply with MIL-STD 2073.
