VALVA provides a specialized range of Nickel and Nickel alloy valves designed for the most aggressive industrial media. These valves are critical for applications where general stainless steel fails, ensuring long-term safety and stability in extremely harsh corrosive environments.
Why Choose Nickel Valves?
Nickel-based alloys offer a unique combination of thermal stability and chemical resistance, making them essential for:
- Exceptional Alkali Resistance: Pure nickel is virtually immune to corrosion in caustic solutions (NaOH, KOH) of all concentrations and temperatures.
- Resistance to Alkali Cracking: Specifically engineered to prevent stress corrosion cracking in high-temperature concentrated alkali conditions.
- Versatility in Severe Media: Our nickel alloy series solves complex corrosion problems in chemical processing, atomic energy, and marine development.
Our Specialized Nickel Material Series
We offer a comprehensive portfolio of nickel-based alloys to meet diverse industrial requirements:
- Pure Nickel Valves: For high-temperature concentrated caustic media.
- Nickel-Copper Alloys (Monel): Excellent for hydrofluoric acid and marine environments.
- Nickel-Chromium-Molybdenum Alloys (Hastelloy): The ultimate defense against pitting and crevice corrosion in reducing and oxidizing media.
- Nickel-Molybdenum Alloys: Specialized for high-concentration hydrochloric acid service.
