Home > Alloy 20 Manifold Valves
Nestled in Hamilton, New Zealand, Mason Tubefittings has built a reputation as a trusted, local source for high-performance fluid handling components. We take particular pride in our Alloy 20 manifold valves, which are engineered to meet the demanding challenges of today’s industrial environments. Crafted with precision and a commitment to quality, these valves are a testament to our dedication to providing durable and reliable solutions for our customers across Aotearoa and beyond, supporting local industry with globally competitive products.
The exceptional resilience of our Alloy 20 manifold valves comes from a specific nickel-chromium-iron alloy, enhanced with molybdenum and copper. This sophisticated composition gives the material outstanding resistance to corrosive substances, particularly sulfuric acid and chloride stress corrosion cracking. This translates into a valve body with superior mechanical strength and impressive toughness, meaning it can withstand high pressures and aggressive chemical environments without compromising its integrity or performance over a long service life.
