Titanium (Grades C-2, C-3, C-5 / B367 GR. C2, C5) Butterfly Valves

Falcon High-Performance Titanium (Grades C-2, C-3, C-5 / B367 Gr. C2, C5) Butterfly Valves

At Falcon, we engineer and manufacture industrial-grade Titanium Butterfly Valves designed for zero-leakage quarter-turn isolation, rapid throttling, and exceptional corrosion resistance in hyper-corrosive chemical, marine, and subsea applications. Cast in high-purity ASTM B367 Grade C-2 / C-5 and forged from ASTM B381 UNS R50400 (Grade 2) / UNS R56400 (Grade 5), our titanium butterfly valves deliver 100% immunity to wet chlorine gas, hypochlorites, high-velocity seawater, and aggressive oxidizing acids in a compact, weight-saving footprint.

Why Choose Falcon Titanium Butterfly Valves?

• Total Immunity to Chlorides & Oxidizing Acids: Titanium forms an instantaneous, self-healing passive oxide film (TiO2), providing complete protection against wet chlorine, hypochlorites, chlorine dioxide (ClO2), fuming nitric acid, and raw seawater.

• Exceptional Strength-to-Weight Advantage: Approximately 45% lighter than equivalent stainless steel or nickel-alloy butterfly valves, drastically reducing piping stress and topside weight on offshore platforms and subsea skids.

• Immunity to Marine Biofouling & Erosion: Resists high-velocity fluid erosion (>30 m/s) and marine organism attachment without requiring chemical antifouling treatments.

• Low Operating Torque & High Reliability: Precision-ground Titanium Grade 5 (Ti-6Al-4V) shafts and polished disc profiles minimize seat friction, extending elastomeric/metal seat life under high cycle frequencies.

• Certified Zero-Leakage Shut-Off: Available in concentric resilient-seated, double-offset, and triple-offset metal-seated designs to deliver certified ISO 5208 Rate A / API 598 bubble-tight shut-off.

Butterfly Valve Configurations Offered

• Concentric PTFE / Elastomer-Lined Titanium Butterfly Valves:

  • Design: Resilient PTFE or EPDM liner fully encapsulates the body interior and disc stem passage for zero metal exposure.

  • Best For: Chlor-alkali chemical feed lines, low-pressure brine loops, and sodium hypochlorite transfer.

• Double-Offset (High-Performance) Titanium Butterfly Valves:

  • Design: Eccentric shaft location lifts the titanium disc off the seat during quarter-turn rotation, preventing seat wear and galling.

  • Best For: High-cycle throttling, reverse osmosis pump isolation, and medium-pressure marine systems.

• Triple-Offset (Bi-Directional Zero-Leakage) Titanium Butterfly Valves:

• Design: Non-rubbing, metal-to-metal seating geometry with a laminated titanium seal ring for extreme temperature and abrasive service.

• Best For: Firewater deluge mains, offshore platform topsides, high-temperature acid lines, and severe slurry streams.

Primary Applications

• Chlor-Alkali & Bleach Manufacturing: Wet chlorine gas scrubbers, sodium hypochlorite lines, and chlorine dioxide ($ClO_2$) paper bleaching loops.

• Desalination & Reverse Osmosis (RO): High-pressure RO membrane isolation, energy recovery turbines, and concentrated brine reject lines.

• Offshore Oil & Gas (FPSO & Topsides): Seawater injection manifolds, produced water handling, ballast management, and firewater systems.

• Chemical & PTA Plants: Purified Terephthalic Acid (PTA) processing, fuming nitric acid manufacturing, and organic solvent recovery.

Quality Assurance & Testing Standards

Every Falcon Titanium Butterfly Valve undergoes rigorous quality inspection before dispatch:

• 100% Positive Material Identification (PMI)
• Hydrostatic Shell & Bi-Directional Seat Testing per API 598 and ISO 5208.
• Non-Destructive Examination (NDE): Radiographic (RT), Liquid Penetrant (PT), and Ultrasonic (UT) testing
• EN 10204 Type 3.1 & Type 3.2 Material Test Reports (MTRs)
