Nickel 201 Ball Valves are expertly crafted valves that provide dependable flow control and shut-off capabilities, even in the toughest chemical and industrial settings. Produced and distributed by Iyle Tube Fittings in South Africa, these valves boast a robust ball mechanism that ensures smooth operation and a tight seal. Thanks to Nickel 201’s remarkable resistance to corrosion, these valves can handle aggressive substances that would typically damage standard materials. With a variety of sizes and pressure ratings available, Nickel 201 Ball Valves deliver leak-proof performance and a long lifespan, making them a top choice for industries that demand reliable, high-quality flow control solutions.
Nickel 201 is a nearly pure nickel alloy, containing at least 99% nickel, and is celebrated for its impressive resistance to reducing acids, alkalis, and various corrosive environments. It features good tensile strength—typically around 400 MPa—along with excellent ductility and high thermal conductivity. Nickel 201 remains mechanically stable across a broad temperature range, from cryogenic conditions up to about 600°C. Its outstanding resistance to stress corrosion cracking and erosion in chloride environments makes it a perfect choice for ball valves used in seawater, chemical processing, and petrochemical applications.
