Home > Alloy 20 Check Valve
For businesses in Hamilton and beyond seeking uncompromising reliability, Mason Tubefittings stands as your trusted local source for specialized fluid control solutions. We proudly manufacture and supply the robust Alloy 20 Check Valve, a product engineered to meet the demanding challenges of corrosive environments. From our base right here in Hamilton, New Zealand, we provide industry with a critical component that combines superior material science with precision craftsmanship, ensuring long-lasting performance and operational safety for your most vital systems.
The exceptional resilience of this valve stems from its unique composition, a nickel-iron-chromium alloy fortified with additions of copper and molybdenum. This sophisticated blend grants it outstanding resistance to sulfuric acid and chloride stress corrosion cracking, outperforming conventional stainless steels. Its mechanical properties are equally impressive, offering high tensile strength and excellent ductility, which allows it to withstand significant pressure fluctuations and physical stresses without compromising its structural integrity or sealing capabilities.

In practice, the Alloy 20 Check Valve is indispensable across a range of tough industries. You’ll find it hard at work in chemical processing plants, handling aggressive acids and solvents, and in pharmaceutical manufacturing where purity and corrosion resistance are non-negotiable. It’s also a cornerstone in food and beverage production, petrochemical applications, and seawater environments. Essentially, wherever highly corrosive media or challenging temperatures are present, this valve acts as a crucial one-way guardian, preventing backflow and protecting sensitive—and often expensive—equipment downstream.
