Product Features & Benefits

  • One-Piece Body The one-piece body eliminates the leak path inherent in a body joint.
  • Strength Equivalent to Metals Designed to achieve strengths equivalent to metals with the inherent corrosion resistance of advanced polymer matrix composite materials.
  • Rugged and Durable For additional ruggedness and durability, the composite check valve has a body designed with heavier wall and flange thickness than metal.
  • Strong, Durable and Light Weight Excellent alternative to high alloy valves. Nil-Cor PFA ball check valves are 50% - 80% lower cost and 1/3 the weight. Saves money on piping supports and makes Nil-Cor polysulfone ball check valves ideal for use on plastic and FRP flanged piping systems.
  • Corrosion Resistant, Safe and Reliable All Nil-Cor ball valves feature lightweight, corrosion resistant bodies, no wetted metallic components and a lock-out as standard equipment.
