Advanced Composite Valves for Use in Corrosive Environments


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.

Leading the Industry for 50 Years

Over one million Nil-Cor valves are in service today. For nearly 50 years, Nil-Cor has been the leader due to a long string of “firsts” in the market;

  • First composite ball valve (1977)
  • First ceramic lined composite valve (1982)
  • First composite characterized control ball valve (1982)
  • First composite butterfly valve (1983)
  • First composite valve to be trusted by the U.S. Navy (1989)
  • First epoxy composite valve (1993)
  • First composite ball check valve (1997)
  • First composite ball valve to receive PED certification (2002)
  • First composite swing check valve (2009)
  • World's largest composite butterfly valve (2013)

Choosing to use Nil-Cor valves in your operation is a big step toward providing the safest, corrosion-free, lowest cost of ownership valve as compared to any other valve in the world.
