An Alloy 20 Manifold Valve is crafted from a nickel-iron-chromium alloy, enhanced with molybdenum and copper, which provides exceptional resistance to sulfuric acid, pitting, and chloride stress-corrosion cracking. Its mechanical properties boast high tensile strength, excellent ductility, and reliability in elevated temperatures and corrosive environments. The valve body is precision-machined, while internal components like stems, seats, and seals are designed for tight shutoff and smooth operation. Alloy 20 remains stable under vibration, pressure cycles, and harsh chemicals, ensuring long-lasting performance in tough processing conditions.
