About the company
Waltron Bull & Roberts, LLC (doing business as Waltron), a veteran-owned and service-disabled veteran-owned small business manufacturer based in Flemington, New Jersey, supplies precision-engineered mechanical and industrial components to the Department of Defense as a prime contractor across purchase orders and indefinite delivery contracts, competing predominantly in full-and-open procurements without set-aside restrictions.
Waltron's manufacturing footprint centers on pumps, pump actuators, diaphragms, gaskets, seals, filter assemblies and elements, covers, fasteners, and specialized mechanical components used in naval vessel maintenance, repair, and logistics operations. Recent representative work includes a $1,198,145 firm fixed-price purchase order from Naval Supply Systems Command (NAVSUP) awarded July 28, 2025, for chemical pumps with subassembly under single-source justification (FAR 6.302-1, government non-ownership of technical data), a $249,999 NAVSUP award on August 15, 2025, for pump actuators, and an $83,875 NAVSUP award on June 20, 2024, for diaphragms. Smaller orders populate the portfolio as well: a $94,793 Total Small Business set-aside from NAVSUP in May 2025 for filter elements, a $67,284 Total Small Business set-aside for filter assembly in February 2025, and recurring gasket orders from Defense Logistics Agency Land and Maritime in the $1,000 to $16,000 range throughout 2024 and 2025.
Customer concentration is heavily skewed toward the Navy. Naval Supply Systems Command accounts for 74 awards and $6.6 million in combined potential value — roughly 95% of recent dollars — with the Defense Logistics Agency, Department of the Army, and other Navy commands splitting the remaining 5%. The vendor has served 20 distinct customer agencies over time, but the Navy's dominance is absolute and consistent across both award count and potential value metrics.
Waltron operates as a 100% prime contractor; the source records no subcontract activity. The vendor sits on multiple indefinite delivery contracts, with documented task order activity under Basic Ordering Agreement N0010485D4655 (3 task orders), Indefinite Delivery Contract DAAK0188C0072 (2 task orders), DAAK0194D0032 (2 task orders), DLA40081C3869 (2 task orders), and DLA40081C5066 (2 task orders). These vehicles are relatively modest and do not represent major vehicle positioning equivalent to a government-wide GWAC or agency-wide IDIQ.
Award activity has been episodic: five awards in 2022, four in 2023, nine in 2024, and ten in 2025, with three recorded in the first seven months of 2026. The vendor faces a recompete exposure of $1.5 million across five awards with ultimate completion dates within the next twenty-four months. Combined potential value across all 221 awards in the source data is $6.9 million, though combined dollars obligated total $14.1 million — a signal of follow-on work or earlier-awarded contracts that exceeded their initial ceiling.
Waltron is a subsidiary of Thomas-Guy LIMITED, a veteran-owned, service-disabled veteran-owned parent company also based in the Northeast (Newtown, Pennsylvania). Thomas-Guy LIMITED carries the same SDVOSB and VOSB designations and operates as the corporate parent; no subordinate structure or sibling subsidiaries are noted in the source. The parent company does not itself hold prime federal contract awards in the current dataset, suggesting Waltron is the operating and contracting entity within the corporate group.
