Quick Summary
The Department of the Navy, specifically NAVSUP Weapon Systems Support Mech, is soliciting proposals for a Parts Kit, Ball Valve (PSC 4820 - Valves, Nonpowered). This is a Total Small Business Set-Aside opportunity, issued under emergency acquisition flexibilities, and designated as a "DO" rated order under the Defense Priorities and Allocations System (DPAS). The material is classified as SPECIAL EMPHASIS material due to its critical use in shipboard systems. Proposals are due by March 17, 2026.
Scope of Work
This solicitation requires a parts kit for a 3-inch Ball Valve, including one Ball (piece 62LI) and two mating Seats (piece 22). Components must conform to NAVSEA Drawings 8617511 and 7285297, and Engineering Report 2640-801X1E1, with specific clarifications provided for drawing 7285297. Material requirements include SAE-AMS-6931 or ASTM-B367 Grade C-5 for the Ball, and Dupont AF DE588 (Teflon Filled Acetal) for the Seats, with detailed physical property specifications.
Stringent testing and certification are required, including hydrostatic or dye penetrant inspection for each Ball, and non-destructive tests for weld repairs. Thread inspection must follow FED-STD-H28 series, and internal threads must be cut, not cold-formed. Ball spherical surfaces require specific finishing processes (grind, hone, polish, grit blast, SUPFINA polishing paste) to achieve a 12-16 RHR finish. Seat stack height and visual inspections are also mandated.
