WILLIAM E WILLIAMS VALVE CORP

William E Williams Valve Corp specializes in the precision manufacturing of industrial valves, gaskets, and current-carrying wiring devices for mission-critical government applications. The company designs and produces high-integrity fluid control components, including ASME Class 150 flanged bronze globe valves with Monel trim, engineered for corrosion resistance and reliability in demanding environments. Their expertise extends to custom sealing solutions and specialized electrical connectors, demonstrating a focused capability in manufacturing components that meet exacting military and federal specifications. Technical proficiency includes material selection for harsh service conditions, tight-tolerance machining, and adherence to ASME and ANSI standards for pressure-containing systems. The contractor has delivered products to the Department of Defense and the Department of Commerce, consistently supplying engineered components for infrastructure, marine, and industrial systems requiring durability and regulatory compliance. For the DoD, they provide sealed gaskets and wiring devices integral to equipment enclosures and control systems, while the Department of Commerce has relied on them for specialized valve assemblies used in environmental or maritime monitoring applications. Their relationship with these agencies reflects a pattern of fulfilling niche, specification-driven procurement needs requiring certified manufacturing processes. Primary focus lies in NAICS 332911 (industrial valve manufacturing), 339991 (gasket and sealing device manufacturing), and 335931 (current-carrying wiring device manufacturing), positioning the firm as a specialized supplier in mechanical and electrical subsystems for federal systems. Their market role is that of a precision component manufacturer serving defense and scientific infrastructure markets, with an emphasis on materials compatibility and dimensional accuracy. As a small business structured as a 2L entity based in Long Island City, New York, William E Williams Valve Corp operates without federal certifications but maintains a focused geographic presence in the Northeast industrial corridor, serving government contractors and direct federal agencies through agile, high-quality production.
