How to bid on Valve, ECS, Repair/Modification for the DEPT of the Navy
What the Navy is buying and why it matters
The Department of the Navy is seeking a contractor to perform repair, upgrade, testing, and inspection services for ECS valves, specifically part number 423775-1. The goal is to return these valves to a ready-for-issue condition.
This opportunity is for firms that can provide all necessary labor, materials, parts, tooling, and test equipment. The work involves disassembling, cleaning, inspecting, repairing, reassembling, and testing the valves according to approved manuals and specifications. This is a critical requirement to maintain naval equipment.
Key dates and what happens at the deadline
This solicitation was published on July 24, 2026. Proposals are due by August 06, 2026, at 4:30 PM ET. Note that an amendment extended the solicitation date to July 16, 2026, and then to December 31, 2025, but the overall deadline for proposals is August 06, 2026.
All proposals must be submitted by the deadline. The government requires proposals to remain valid for a minimum of 120 days after submission. Failure to provide all required data, especially for source approval, will result in your proposal not being considered for award.
Who this opportunity suits
This is a sole-source requirement, meaning the government currently intends to contract with a specific source because it lacks sufficient data to contract with others. However, new vendors can still pursue this opportunity.
This bid is suitable for companies with expertise in the repair, overhaul, and testing of complex equipment, particularly valves and related components. Crucially, Government Source Approval is required before award. If you are not an approved source, you must submit detailed information as outlined in the NAVSUP WSS Source Approval Brochure along with your proposal. The relevant NAICS code for this type of work is 336413.

Practical tips for a competitive response
Given the sole-source nature and the requirement for Government Source Approval, prioritize demonstrating your firm's technical capabilities and experience with similar repair and overhaul work. Clearly articulate how your company meets or exceeds the technical specifications, including MIL-STD-130 markings and compliance with IPC/EIAJ-STD-001C if MIL-STD-454 is referenced.
Pay close attention to the definitions of 'overhaul' and 'repair' provided in the Statement of Work and ensure your proposal directly addresses these requirements. Since the government will not provide special tooling or test equipment, clearly state your firm's ability to provide all necessary resources. Ensure your proposal is complete and addresses every requirement, especially the source approval documentation, to avoid disqualification.
