Over a Century of Quality, Innovation, and Flow Control Expertise
In high-stakes industrial fluid handling, protecting equipment and maintaining flow integrity depends entirely on the reliability of pipeline components. For over a century, Keckley Company has stood as one of North America's premier manufacturers of pipeline strainers, ball valves, check valves, and specialty flow control products.
From severe-service petrochemical refineries to critical commercial HVAC systems, Keckley engineering is specified when failure is not an option.
A Century-Long Legacy: From Springfield to Skokie
Founded in 1914 by O. C. Keckley in Springfield, Illinois, the company initially focused on basic steam and liquid control equipment. Built on a foundation of family-owned leadership that spans four generations, Keckley quickly developed a reputation for precise machining, heavy-duty castings, and reliable customer service.
-
1955: To support exponential postwar growth in process manufacturing and construction, Keckley expanded operations into a modern manufacturing facility in Skokie, Illinois, where its headquarters remain today.
-
1962: Keckley acquired Klipfel Valves, expanding its engineering capabilities and integrating advanced float, lever, and control valve designs into its core catalog.
-
2016 to Present: Keckley became an early leader in emissions compliance, becoming one of the first major valve manufacturers to certify its complete ball valve line to the stringent API 641 fugitive emissions standard.
Innovation in Design and Manufacturing
Keckley's reputation for quality stems from rigorous engineering, advanced metallurgy, and strict quality control. Operating an ASME-certified code shop (with ASME "U" stamp capabilities available upon request), Keckley combines traditional casting strength with modern precision.
-
API 641 Fugitive Emissions Compliance: To protect environmental safety and meet strict EPA standards, Keckley ball valves feature engineered stem sealing systems tested to restrict volatile organic compound (VOC) leakage to under 100 ppm.
-
Precision Machined Screen Seats: In both cast Y-strainers and basket strainers, Keckley machines true internal body grooves and seats. This guarantees exact alignment of the screen element, preventing debris bypass under high differential pressures.
-
Custom ASME Fabrication: When off-the-shelf cast strainers cannot fit space constraints or unusual nozzle layouts, Keckley fabricates custom Y-strainers, duplex basket strainers, and tee-strainers engineered specifically for offset piping configurations.
