Quick Summary
The Department of the Navy, through NAVSUP Weapon Systems Support Mechanicsburg, has issued a Solicitation for Valve Seats (PSC 4810). This requirement is a Total Small Business Set-Aside for the procurement of specialized seats for 1 1/2 and 2-inch ball valves, designated as SPECIAL EMPHASIS material (Level I/SUBSAFE) due to their critical use in shipboard systems. Proposals are due by February 20, 2026.
Scope of Work
This solicitation requires the supply of valve seats manufactured from Delrin: Dupont AF DE588 (Teflon Filled Acetal), conforming to Newport News Shipbuilding Drawing 255584, Piece 19, and specific material properties detailed in the solicitation.
