Atlantic Valve & Supply Inc.

Atlantic Valve & Supply Inc., a for-profit marine and industrial valve and pipe fitting supplier based in Curtis Bay, Baltimore, Maryland, operates as a prime contractor delivering valves, fittings, tubing, expansion joints, strainers, and related plumbing components to the U.S. Coast Guard and other maritime federal agencies. The vendor competes predominantly under total small business set-asides, which account for approximately 70 percent of its contract portfolio, though it also wins unrestricted, full-and-open awards with the Coast Guard and other customers.

The company's customer concentration is extreme and heavily skewed toward one agency. The Coast Guard accounts for 1,077 of 1,497 total prime awards (72% of award count) and $9.8 million of the $13.4 million combined potential value across all awards (73% of dollars). The gap between the two metrics reflects the vendor's positioning as a high-volume, routine supplier to the Coast Guard Surface Forces Logistics Center in Baltimore, with individual purchase orders typically ranging from $10,000 to $100,000. Secondary maritime customers with much smaller footprints include the Defense Logistics Agency (42 awards, split across Land and Maritime subcategories), the National Oceanic and Atmospheric Administration (4 awards, $127 thousand), the Maritime Administration (3 awards, $67 thousand), and the Naval Sea Systems Command and Military Sealift Command (5 and 5 awards respectively). Across the full portfolio, the vendor serves 16 distinct customer agencies, though the Coast Guard relationship dominates by an order of magnitude.

Representative recent prime work spans late 2025 and early 2026: a $75,844 total small business set-aside purchase order from the Coast Guard (March 4, 2025) for 20 different industrial valves including ball, gate, relief, and check valves; a $83,704 total small business set-aside delivery (March 7, 2025) of thermocouple assemblies, pressure gauges, and transducers; a $59,687 total small business set-aside for elbows, tees, and valves (October 21, 2025); and a $32,440 unrestricted full-and-open purchase order (May 27, 2026) for a safety relief valve. The company also fulfills specialized vessel-specific contracts such as a $133,048 award for pipe fittings supporting the cutter Hollyhock and a $58,150 delivery for the cutter Legare, both total small business set-asides reflecting the vendor's role in sustaining Coast Guard shipyard operations at Curtis Bay.

The vendor sits on one named parent vehicle — Blanket Purchase Agreement HSCG4005A80003, which carries 39 task orders. The source also references secondary DLA IDICs (DLA70081C1281, DLA70081C1427, DLA70081C3294, DLA70081C4349), each with 2 task orders, indicating minimal leverage on defense supply mechanisms relative to the Coast Guard purchasing dominance.

Activity has contracted sharply in recent years. The vendor received 36 awards in 2022, 28 in 2023, 12 in 2024, rebounded to 34 in 2025, and shows only 4 awards year-to-date in 2026. The combined potential value of three awards completing ultimate delivery within the next twenty-four months is $69 thousand, a minimal recompete exposure reflecting the vendor's transactional, purchase-order-driven business model with short performance cycles and frequent re-solicitation.

The vendor subcontracts minimally — only one sub-award appears in the source data, a January 2023 sub engagement with Electric Boat Corporation for overtime premium coverage. This 0.07 percent sub-award share confirms Atlantic Valve & Supply operates almost entirely as a prime contractor on spot procurements rather than integrating into larger defense or maritime system programs.

The vendor's capability footprint is narrow and specialized. The top five NAICS categories span industrial supplies merchant wholesale (534 awards), industrial valve manufacturing (236 awards), plumbing and heating equipment supplies (215 awards), steam and air-conditioning supply (78 awards), and other metal valve and pipe fitting manufacturing (58 awards). The top five PSC assignments are nonpowered valves (495 awards), hose/pipe/tube/lubrication/railing fittings (432 awards), miscellaneous ship and marine equipment (118 awards), pipe/tube/rigid tubing (108 awards), and powered valves (94 awards). This category concentration reflects a vendor that stocks and delivers commodity and semi-custom maritime plumbing components — gatekeeping inventory for Coast Guard yard maintenance rather than performing engineering or systems integration work.
