Titanium Gate Valve

Falcon High-Performance Titanium (Grades C-2, C-3, C-5 / B367 Gr. C2 & ASTM B381 Gr. F-2) Gate Valves

At Falcon, we engineer and manufacture industrial-grade Titanium Gate Valves designed for severe bi-directional isolation in hyper-corrosive marine, offshore, and petrochemical process environments. Available in cast ASTM B367 Grade C-2 / C-5 and forged ASTM B381 Grade 2 / Grade 5 (UNS R50400 / UNS R56400), our gate valves offer complete immunity to seawater erosion, wet chlorine gas, organic acids, and aggressive oxidizing media.

Key Features & Advantages

• Unrivaled Corrosion Immunity: Titanium’s self-healing oxide film ($TiO_2$) provides near $100\%$ resistance to seawater, marine biofouling, wet chlorine gas, hypochlorites, nitric acid, and high-velocity brine.

• Full-Bore Bi-Directional Isolation: Precision-machined wedge and straight-through flow design deliver maximum flow capacity with minimal pressure drop across the pipeline.

• Superior Strength-to-Weight Ratio: Approximately $45\%$ lighter than equivalent stainless steel or nickel-alloy valves, significantly reducing structural piping load on offshore platforms and skid assemblies.

• Anti-Galling OS&Y Stem Construction: Outside Screw & Yoke (OS&Y) design keeps operating stem threads outside the wetted process area, preventing thread corrosion and galling under high operating cycles.

• Certified Low Fugitive Emissions: Certified low-emission stem packing gland arrangements (API 622 / ISO 15848-1) prevent hazardous chemical leakage into the environment.

Gate Valve Construction Types Offered

• Bolted Bonnet (BB) Cast Titanium Gate Valves:

  • Design: Heavy-duty bolted bonnet construction with a flexible wedge disc to accommodate piping thermal stress.

  • Best For: Large-bore seawater intake, desalination headers, and Class 150 to Class 600 chemical lines.

• Forged Titanium Small-Bore Gate Valves ($1/2"$ to $2"$ — Class 800 / 1500):

  • Design: Compact forged construction (API 602) in ASTM B381 Grade 2 with Socket-Weld, Threaded, or Flanged ends.

  • Best For: High-pressure sampling, instrument isolation, drain, and vent service.

• Pressure Seal Bonnet (PSB) Gate Valves:

  • Design: Utilizes internal line pressure to energize the bonnet seal, increasing joint tightness as pressure rises.

  • Best For: Ultra-high pressure severe process applications (Class 900 to Class 2500).

• Bellows-Sealed Titanium Gate Valves:

  • Design: Features a welded titanium metallic bellows seal surrounding the stem for absolute Zero-Fugitive-Emission containment.

  • Best For: Highly toxic, volatile, or lethal chemical streams.

Primary Applications

• Desalination & Reverse Osmosis (RO): High-pressure RO feed pumps, brine isolation, and energy recovery systems.

• Marine & Offshore Platforms: Seawater cooling systems, ballast water management, subsea manifolds, and firewater loops.

• Chlor-Alkali & Bleach Plants: Isolation in wet chlorine gas scrubbers, sodium hypochlorite lines, and chlorine dioxide ($ClO_2$) feeds.

• PTA & Chemical Processing: Purified Terephthalic Acid (PTA) production, nitric acid manufacturing, and organic solvent recovery.

Quality Assurance & Testing Standards

Every Falcon Titanium Gate Valve undergoes rigorous factory verification before shipment:

• 100% Positive Material Identification (PMI) on body, bonnet, wedge, and stem materials to confirm exact titanium grade.

• Hydrostatic Shell & High/Low-Pressure Seat Testing per API 598 and ISO 5208.

• Radiographic (RT) & Dye-Penetrant (PT) surface examination per ASME B16.34 / ASTM standards.

• EN 10204 Type 3.1 & Type 3.2 Material Test Reports (MTRs) for complete heat traceability.
