2. Lightweight & High Strength: Density of 4.51g/cm³, 30% lighter than duplex steel valves of the same size, tensile strength ≥345MPa.
3. Zero Leakage Sealing: PTFE/FEP lined sleeves + graphite packing meet API 598 Class VI zero leakage standard.
4. High Purity Compatibility: Low impurity content, ideal for ultra-pure fluid transfer in semiconductor and pharmaceutical industries.
TA2 (Gr2) Titanium Plug Valve: Engineered for Extreme Corrosive Environments
I. Product Attributes: Tailored for Corrosive Fluid Handling
1. TA2 Titanium Alloy Construction
• Base Material Advantage: TA2 (Gr2) titanium alloy core components (valve body, plug, stem) deliver exceptional corrosion resistance to seawater, chlorides, organic acids, and oxidizing media (e.g., nitric acid, chromic acid). Compatible with pH 0–14 chemical environments, outperforming stainless steel in harsh marine and chemical processing applications.
• Mechanical Performance: Cold-workable TA2 titanium ensures high tensile strength (≥345 MPa) and ductility (elongation ≥20%), with a density of 4.51 g/cm³ for lightweight yet robust valve design (30% lighter than duplex steel valves of the same size).
2. Advanced Sealing & Structural Design
• PTFE/FEP Lined Seals: TA2 titanium valve body paired with PTFE/FEP-lined sleeves + flexible graphite packing achieves API 598 Class VI zero leakage, ideal for corrosive fluid shutoff and control.
• Integral Forged Body: One-piece forged TA2 titanium valve body eliminates weld joints, reducing corrosion points and ensuring pressure rating up to PN160 (2320 psi) and temperature resistance from -50°C to 150°C.
• Anti-Corrosion Coating: Exterior surfaces feature electroplated passivation treatment (TiO₂ film) to enhance resistance to crevice corrosion and pitting in chloride-rich environments (critical pitting temperature ≥100°C).
II. Core Functions: Solving Corrosive Fluid Control Challenges
• Corrosion Mitigation: TA2 titanium construction prevents material degradation in aggressive media (e.g., seawater desalination, brine processing, chemical waste treatment), extending valve service life by 5–10x compared to carbon steel valves.
• High-Purity Fluid Compatibility: TA2 titanium’s low impurity content (Fe ≤0.3%, C ≤0.1%) avoids contamination of ultra-pure chemicals, making it suitable for semiconductor wafer fabrication and pharmaceutical API production.
• Low Maintenance Operation: Smooth titanium surface reduces fluid friction and scaling; the quarter-turn plug design enables quick on/off (≤1 second actuation) with minimal torque, lowering operational downtime.
