What the government is buying
The Naval Supply Systems Command (NAVSUP) Weapon Systems Support unit in Mechanicsburg, Pennsylvania is soliciting offers for a valve, check, special—specifically designated "CHK SPCL42X46" under classification code 4820. This falls within the broader category of fluid power and plumbing equipment procurement.
Valves in this classification are typically used in shipboard or shore-based systems to control fluid direction and prevent backflow. NAVSUP WSS Mechanicsburg serves as a primary inventory control point for the Navy, managing spare parts and equipment sustainment for naval weapons systems and platforms. The "special" designation suggests this may be a non-standard or military-specification item rather than a commercial off-the-shelf product.

Who can bid
This is a full and open competition with no small business set-aside, meaning businesses of any size may submit offers. The NAICS code 332919 covers manufacturers of metal valves (except industrial valves), pipe fittings, and related products. Eligible bidders typically include:
- Manufacturers with experience producing valves to military or maritime specifications, including MIL-SPEC, MIL-STD, or NAVSEA standards
- Distributors who qualify as manufacturers under the nonmanufacturer rule (if applicable; see the solicitation for size standard and source requirements)
- Small businesses that meet the SBA size standard for NAICS 332919 (1,000 employees; verify current standard)
Given the Navy's operational demands, prior experience with defense procurement systems, quality assurance programs, and traceability documentation will strengthen a bid. Firms should confirm whether they meet any applicable domestic source requirements, such as the Berry Amendment or Buy American Act, which commonly apply to Navy shipboard components.
How to put together a competitive bid
Verify technical requirements. The "special" designation and classification code 4820 indicate this likely references a specific drawing, specification, or part number. Request or download the full technical data package from SAM.gov to confirm dimensional, material, pressure rating, and testing requirements.
Assess qualification prerequisites. Navy valve procurements often require:
- Quality system certification (ISO 9001 or equivalent)
- NIST SP 800-171 cybersecurity compliance for Controlled Unclassified Information
- Registration in the SAM database (active at time of award)
- Past performance documentation for similar defense deliverables
Review source restrictions. Shipboard valves frequently fall under specialty metals or domestic preference rules. Determine whether foreign components are permitted and whether domestic end products are mandated.
Structure pricing carefully. NAVSUP WSS procurements typically evaluate on price and technical acceptability. Ensure your proposal addresses:
- Firm fixed-price or other pricing structure required
- Delivery schedule and any expedited requirements
- Packaging and marking per MIL-STD-129 or specified standards
- Warranty terms
Submit through proper channels. Follow instructions for electronic submission via the System for Award Management or designated portal, with attention to format and deadline.
