Titanium Check Valves

Falcon High-Performance Titanium (Grades C-2, C-3, C-5 / B367 Gr. C2, C3, C5) Check Valves

At Falcon, we engineer and manufacture industrial-grade Titanium Check Valves designed to deliver automatic, rapid-closing backflow prevention in extreme marine, offshore, and hyper-corrosive chemical environments. Cast in high-purity ASTM B367 Grade C-2 / C-3 / C-5 (Cast Titanium) and forged from ASTM B381 UNS R50400 (Grade 2) / UNS R56400 (Grade 5), our non-return check valves protect pumps, heat exchangers, and reverse osmosis systems from severe pressure surges, reverse fluid flow, and water hammer.

Key Features & Advantages

• Unrivaled Corrosion Resistance in Chlorides & Seawater: Titanium forms an instantaneous, self-healing passive oxide film ($TiO_2$), providing virtually $100\%$ immunity to seawater, wet chlorine, hypochlorites, nitric acid, organic acids, and high-velocity brine erosion.

• Exceptional Strength-to-Weight Ratio: Roughly $45\%$ lighter than stainless steel or nickel-based alloys of equivalent pressure rating, significantly reducing structural load on offshore topsides and subsea skids.

• Rapid Non-Slam Backflow Protection: Precision-balanced discs and optimized internal flow passages ensure immediate reaction to reverse flow, preventing destructive hydraulic shock and equipment damage.

• Anti-Galling Internal Hardware: High-strength Titanium Grade 5 (Ti-6Al-4V) hinge pins, shafts, and springs ensure smooth disc pivoting without binding or galling over long operational cycles.

• Zero-Leakage Seating Options: Micro-finished, lapped Titanium-to-Titanium seating surfaces deliver tight shut-off conforming to API 598 and ISO 5208 Rate A / B.

Titanium Check Valve Designs Offered

• Swing Check Valves:

  • Design: Top-hinged disc design swinging fully open under forward pressure.

  • Best For: Full-bore flow capability with minimal pressure drop across horizontal and vertical-up liquid and gas lines.

• Piston / Lift Check Valves:

  • Design: Utilizes line pressure to lift a guided piston disc off the seat.

  • Best For: High-pressure, high-velocity gas and liquid streams requiring ultra-fast, spring-assisted backflow closure.

• Dual-Plate (Wafer) Check Valves:

  • Design: Compact, lightweight wafer design equipped with twin spring-loaded titanium plates.

  • Best For: Non-slam, rapid closure in tight piping footprints and weight-critical offshore top-side modules.

• Tilting Disc Check Valves:

  • Design: Designed with a pivoted disc that closes before reverse flow velocity drops to zero.

  • Best For: Minimizing fluid hammer and pressure surges in high-flow marine pump discharge lines.

• Ball Check Valves:

  • Design: Compact, small-bore ($1/2"$ to $2"$) high-pressure designs using a titanium ball guide system.

  • Best For: Aggressive chemical feed, sampling lines, and metering pump outlets.

Seating & Leakage Performance

• Titanium-to-Titanium Metal Seats (Standard): Precision-ground and lapped seating conforming to API 598, ISO 5208 Rate B, and ANSI/FCI 70-2 Class IV / V.

• Soft-Seated Inserts (Optional): PTFE, RTFE, Viton, or Devlon inserts embedded in the disc for ISO 5208 Rate A / FCI 70-2 Class VI (Zero-Leakage / Bubble-Tight) performance.

Quality Assurance & Testing Standards

Every Falcon Titanium Check Valve undergoes comprehensive inspection before shipment:

• 100% Positive Material Identification (PMI) on all pressure parts and internal trims to confirm exact titanium alloy grade.

• Hydrostatic Shell & 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 number and mill traceability.
