Polysulfone Ball Check Valves
Nil-Cor® Ball Check Valves, Fiberglass Reinforced Polysulfone Ball Check Valves: 1”-4” (410 Series) are used for corrosive chemical service used in construction of pressurized piping systems.
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.
