VALVA specializes in high-performance titanium valves engineered for the most demanding corrosive environments. By utilizing the unique self-passivation properties of titanium, our valves provide a level of safety and longevity that standard stainless steel, copper, or aluminum cannot match.
The Science of Corrosion Resistance
The exceptional performance of titanium is driven by its high affinity for oxygen. In the presence of oxygen, titanium instantly forms a dense, stable, and self-repairing passive oxide film on its surface.
- Self-Healing Protection: Even if the surface is physically damaged, the oxide film regenerates immediately in oxygen-rich environments.
- Enhanced Stability: For high-temperature or low-pH reducing media, we employ surface ion modification and anodizing treatments to further strengthen the passive film and increase surface hardness.
Key Application Areas
Titanium valves are cost-effective solutions for industries where equipment failure is not an option:
- Marine & Offshore: Immune to corrosion in seawater, fresh water, and high-temperature steam.
- Chemical & Fertilizer: Excellent resistance to aqua regia, sodium hypochlorite, nitric acid, and wet oxygen.
- Alkaline & Soda Ash: Highly resistant to alkaline media and ammonia ions.
- Aerospace: Utilizing titanium’s lightweight properties (specific gravity 4.507) and high mechanical strength.
- Fine Chemicals & Pharma: Reliable performance in organic acids and inorganic salt production.
