Titanium Alloy Triple-Offset Wafer Butterfly Valve

🔑 Advanced Design and Sealing Technology

• Triple Eccentric Metal Sealing: The core is the three-dimensional eccentric metal sealing structure, which ensures the disc cams out of and into the seat without rubbing, minimizing wear.
• Sealing Configuration Options:
  • Metal-to-Metal Seal: Provides the highest temperature resistance and durability.
  • Interchangeable Metal Seal Ring: Offers flexibility for maintenance.
  • Titanium Plate + High-Performance Composite Seal: (PTFE or Flexible Graphite) for enhanced sealing in specific applications.
• Temperature Range: The specialized sealing system guarantees high sealing performance across the full temperature range, from ultra-low (cryogenic) to ultra-high temperatures.
• High Flow Efficiency: Features a small structural length and overall height, fast opening/closing speed, and excellent flow control characteristics. Its design is particularly well-suited for large-diameter valves.

🔬 Titanium’s Chemical Performance

Titanium is selected for its superior corrosion profile, especially in:

• Alkaline Media: Shows strong resistance to corrosion.
• Chloride (Cl⁻) Environments: Possesses exceptionally strong resistance to chloride ion attack, preventing stress corrosion cracking common in stainless steels.

⚠️ CRITICAL WARNING: SAFETY & MATERIAL LIMITATIONS

The exceptional strength and corrosion resistance of Titanium come with specific, severe constraints that must be considered for safe operation:

• Hydrogen Embrittlement: The ingress of hydrogen into the Titanium structure can lead to Hydrogen Embrittlement, resulting in catastrophic failure.
• Stress Corrosion & Crevice Corrosion: Special attention must be paid to the potential for pitting, crevice corrosion, and stress corrosion cracking within the operating media.
• Spontaneous Combustion Risk: Titanium can be pyrophoric (spontaneously combust) under certain conditions.

$\rightarrow$ Strict Prohibition: Titanium valves are strictly prohibited from use in any working environment where the risk of the catastrophic failures listed above (hydrogen absorption, stress corrosion, or spontaneous combustion) exists.
