What the government is buying

The Naval Supply Systems Command (NAVSUP) Weapon Systems Support unit in Mechanicsburg, Pennsylvania is soliciting offers for a plug valve. This is a procurement under Federal Supply Classification (FSC) 4820, which covers valves and related hardware used in fluid control systems. Plug valves are quarter-turn valves with a cylindrical or conically tapered plug that rotates to open or close flow passages, commonly employed in piping systems across naval vessels and shore facilities for shutoff and diverter applications.

NAVSUP Weapon Systems Support serves as the Navy's primary provider of supply chain management for weapons systems support, including spare parts and maintenance items for naval platforms. See the solicitation for specific valve technical requirements, quantities, and delivery expectations.

Key facts

Who can bid

This solicitation is unrestricted—any responsible offeror may submit a bid, including small and large businesses. There is no set-aside designation, meaning competition is open to all qualified manufacturers and suppliers of industrial valves.

Under NAICS 332919, "Other Metal Valve and Pipe Fitting Manufacturing," the Small Business Administration size standard is generally 500 employees. Firms manufacturing or distributing plug valves meeting Navy specifications and quality requirements are eligible to compete. See the solicitation for any additional qualifications, certifications (such as ISO 9001 or NAVSEA approvals), or past performance requirements.

How to put together a competitive bid

For industrial valve procurements to military customers, bidders should focus on several practical areas:

Technical compliance: Review the drawings, specifications, and performance requirements carefully. Navy valve procurements often reference military specifications (MIL-SPECs) or commercial item descriptions with specific material, pressure rating, and dimensional requirements. Obtain any referenced standards early and confirm your product meets all salient characteristics.

Quality assurance: NAVSUP typically requires adherence to strict quality systems. Prepare documentation of your quality control processes, material certifications, and testing capabilities. If the valve requires special surface treatments, welding qualifications, or non-destructive testing, ensure your facility or subcontractors hold current certifications.

Past performance: Be ready to document relevant delivery history, particularly for defense or maritime customers. On-time delivery and quality acceptance rates matter for competitive positioning.

Pricing strategy: As unrestricted competition, expect price to be a significant evaluation factor. Analyze your manufacturing or sourcing costs carefully. Consider whether Small Business status, veteran ownership, or other socio-economic factors apply to your business—while not a set-aside, these may still factor in source selection criteria or subcontracting plans.

Packaging and preservation: Military supplies require specific packaging to prevent corrosion and damage during extended storage and transit. Factor these requirements into your pricing.
