Titanium Knife Gate Valves

For your website, here is a professional, original technical brief for Falcon Titanium Knife Gate Valves. Titanium is often the ultimate solution for weight-sensitive applications and environments involving high-strength chlorides.

Falcon Titanium Knife Gate Valves

Ultimate Chemical Immunity & High Strength-to-Weight Performance

Falcon Titanium Knife Gate Valves represent the pinnacle of corrosion resistance for extreme industrial service. Utilizing Titanium Grade 2 (UNS R50400) or Grade 5 (UNS R56400), these valves provide an inert barrier against the most aggressive corrosive agents that would degrade even high-nickel alloys like Hastelloy.

1. The Titanium Advantage

Titanium’s legendary resistance is due to the spontaneous formation of a stable, protective oxide film on its surface.

• Chloride Immunity: Virtually immune to pitting and crevice corrosion in seawater, brackish water, and brine, even at elevated temperatures.

• Oxidizing Environments: Exceptional performance in nitric acid, chromic acid, and wet chlorine gas.

• Erosion-Corrosion Resistance: The hard oxide layer makes titanium highly resistant to high-velocity flow and abrasive slurries.

• Weight Efficiency: Titanium is approximately 45% lighter than steel, making these valves ideal for offshore platforms and weight-sensitive piping systems.

2. Engineering & Design Features

• Precision Machined Gate: We use solid titanium plates ground to an ultra-smooth finish. This minimizes friction against the seats and packing, drastically reducing the torque required for automation.

• Inert Seating Technology: Available with specialized reinforced PTFE or Metal-to-Metal seats designed to maintain a seal in high-cycle chemical processing.

• Cavity-Free Body: The internal geometry is designed to prevent "dead zones," ensuring that aggressive media does not accumulate and create localized chemical reactions.

• Cryogenic Capability: Titanium maintains its mechanical properties in extreme cold, making it suitable for specialized cryogenic chemical applications.

4. Strategic Industry Applications

Falcon Titanium valves are the first choice for:

• Desalination & Water Treatment: High-temperature brine heaters and seawater intake lines where zero corrosion is required.

• Chemical Processing: Handling wet chlorine, chlorates, and hypochlorites in chlor-alkali plants.

• Pulp & Paper: Bleach plant stages using chlorine dioxide or ozone.

• Hydrometallurgy: Gold and nickel leaching processes involving high-pressure oxidizing acids.

• Aerospace & Marine: Applications requiring a combination of high strength, low weight, and salt-air resistance.

Quality & Verification

To ensure the integrity of our titanium builds, Falcon provides:

1. PMI Verification: To confirm the specific grade of titanium and oxygen content.

2. Specialized Welding: Titanium requires an inert gas (Argon) environment for welding; our certified welders ensure every joint is free of contamination.

3. Dye Penetrant Inspection: Conducted on all sealing surfaces to ensure a 100% flaw-free finish.

4. Traceability: Full EN 10204 3.1 certification provided with every valve.

Technical Comparison: Titanium vs. Stainless Steel (316L)

While Stainless Steel 316L is a versatile material, it has significant limitations in high-chloride or highly oxidizing environments where Titanium thrives.
