Design:
Nil-Cor Flanged ball valves feature a one-piece body, eliminating the leak path inherent in a body joint. Nil-Cor face-to-face dimensions meet ANSI B16.10. Our streamlined standard port design delivers low pressure loss while keeping actuation torque and cost to a minimum. To impart ruggedness and durability, our composite valve body is designed with heavier wall and flange thicknesses than metal or plastic valves. All Nil-Cor valve stems are blow-out proof for safety. Nil-Cor offers the only standard Self-Relieving seat in the industry, eliminating the need to drill holes in the ball for cavity pressure relief. Our optional Cavity Filler CF seat sets the design standard for rugged, durable performance in slurries and dirty services.
Materials of Construction
Nil-Cor Flanged Ball Valves are available in either glass or graphite fiber-reinforced vinyl ester or novolac epoxy, as well as glass fiber reinforced polysulfone. The balls in Nil-Cor ball valves are made from fiber-reinforced resin providing both strength for resistance to torsional actuation loads and lubricity to minimize actuation torque. The graphite reinforcement also reduces potential fouling since line media tend not to adhere to it, and the seats easily wipe clean further minimizing breakaway torque. Our stem features a massive Hastelloy-C insert for outstanding strength and corrosion resistance. The packing gland and gland bolts are Hastelloy-C to ensure corrosion-free operation in the harshest environments.
