Controlworx, L.l.c

Controlworx LLC, a Louisiana-based limited liability company and child entity of John H Carter Co Inc., supplies specialized industrial valves, pressure regulators, and control systems equipment to federal agencies as a prime contractor (67% of recent awards) and as a subcontractor to defense and energy primes. The vendor competes on a full-and-open basis with no small-business set-aside footprint.

Controlworx operates from Baton Rouge, Louisiana, and draws its recent federal work across two distinct capability streams. Its prime awards center on industrial valve and pressurization equipment — pressure regulators, relief valves rated between 50 and 835 psi, isolation valves, and check valves, predominantly brand-restricted to Emerson Tescom and Anderson Greenwood authorized reseller products, with Material Test Reports and Certificates of Conformance required. Recent representative prime work includes a $352,318.47 purchase order from NASA's Shared Services Center for PR Station-HP Gas Facility pressurization valves (May 27, 2026, ultimate completion September 16, 2026) and a $75,096.00 order from the Shared Services Center for Anderson Greenwood spare pilot controller components (awarded September 2, 2026). Its subcontract footprint concentrates almost entirely under Fluor Federal Petroleum Operations, LLC on the Strategic Petroleum Reserve facilities management and operations contract, where Controlworx supplies DCS (Distributed Control System) modules, DeltaV Guardian support systems, and DCS workstation monitoring equipment across multiple fiscal-year task orders between 2023 and 2026.

Customer concentration is heavily skewed toward NASA's Shared Services Center ($427 thousand combined potential value across two awards, 84% of all potential dollars) and the Department of Energy's Cyber Security office (seven awards by count, though dollar magnitude is not specified in the source). The Department of the Army Mississippi Army National Guard and the Department of the Air Force Global Strike Command account for the remaining named federal work. Total combined potential value across all twenty-one awards is $506 thousand, though obligated dollars ($1.5 million) exceed potential value, indicating sustained performance and modification activity on existing awards. Two awards (combined potential value $427 thousand) reach ultimate completion within the next twenty-four months.

The award footprint reflects capability concentration in industrial valve manufacturing (NAICS 333911, Industrial Valve Manufacturing) and facilities support services (NAICS 811412, Commercial and Industrial Machinery and Equipment Repair and Maintenance). Activity has remained episodic over the past five years — one award in 2013 and 2023, ramping to three awards in both 2025 and 2026 — with no presence on government-wide vehicles or indefinite-delivery vehicles visible in the source data.
