Nil-Cor®

Nil-Cor is the original and market leading composite valve designer and manufacturer in the world. Since 1977, Nil-Cor valves have been displacing traditional steel or alloy valves in the most corrosive industrial applications and environments. Using proprietary mechanical and structural designs while employing specifically engineered resin, fiberglass, and graphite composite materials, Nil-Cor valves provide the most optimum combination of light weight, strength, and corrosion-free features of any valve available on the market today.  

Global demand of non-metallic composite and fiberglass reinforced piping (FRP) systems and tanks is on the rise to meet the growing use and production of corrosive fluid applications in chemical, mining, wastewater, and other caustic environments. To support these needs, Nil-Cor provides a full range of ball, butterfly, and check valves to enable the safest and most reliable composite valve solution in the world.
