Product Features & Benefits

  • ONE-PIECE BODY: The one-piece body eliminates the leak path inherent in a body joint.
  • STRENGTH EQUIVALENT TO METALS: Nil-Cor® ball check valves are 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 ball check valves are 50% - 80% lower cost and 1/3 the weight. Saves money on piping supports and makes Nil-Cor 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.
