Inconel 625 (UNS N06625 / CW6MC) Globe Valves

Falcon High-Performance Inconel 625 (UNS N06625 / CW6MC) Globe Valves

At Falcon, we engineer and manufacture industrial-grade Inconel 625 Globe Valves designed for severe-service throttling, linear flow regulation, and high-pressure isolation in the world’s most hyper-aggressive marine, offshore, and chemical processing environments. Cast in high-purity ASTM A494 Grade CW6MC (Cast Inconel 625) and forged from ASTM B564 / B446 UNS N06625, our Inconel 625 globe valves deliver an extreme PREN≥45, complete immunity to chloride stress-corrosion cracking (SCC), and exceptional mechanical integrity from cryogenic conditions down to −196 °C up to severe thermal service at +1000°C.

Key Features & Advantages

• Extreme Pitting & Crevice Corrosion Resistance: High molybdenum (∼9%) and niobium (∼3.5%) content provides a high Pitting Resistance Equivalent Number (PREN≥45), guaranteeing absolute protection against localized pitting and crevice attack in hot aerated seawater, geothermal brine, and mixed acid media.

• Immunity to Stress-Corrosion Cracking (SCC): High nickel matrix (>58%) provides 100% protection against chloride-induced stress corrosion cracking and sulfide stress cracking (SSC) in high-pressure sour gas (H2S) streams.

• Precision Throttling & Anti-Cavitation Trim: Engineered with plug, parabolic, or needle disc geometry to deliver fine flow control, linear regulation, and erosion-resistant throttling under extreme pressure drops.

• High Thermal & Mechanical Strength: Solid solution-strengthened structure preserves high tensile yield strength and creep-rupture performance without thermal scaling under high differential pressures.

• Heavy-Duty OS&Y Construction: Outside Screw and Yoke (OS&Y) design keeps stem threads isolated from aggressive line media, preventing stem thread corrosion and galling while providing visual open/close position indication.

Globe Valve Design Configurations Offered

• API 623 Bolted Bonnet Inconel 625 Globe Valves:

  • Design: Heavy-duty cast body with guided plug disc to eliminate vibration and cavitation during high-differential throttling (2" to 16").

  • Best For: Offshore topside bypass lines, severe chemical feeds, and high-pressure seawater throttling.

• API 602 Forged Inconel 625 Globe Valves:

  • Design: Heavy-wall forged body with bolted or welded bonnet for high-pressure, small-bore piping systems (1/2" to 2").

  • Best For: Chemical injection skids, sampling loops, instrument take-offs, and high-pressure vent/drain isolation.

• Y-Pattern & Angle Pattern Inconel 625 Globe Valves:

• Design: Y-pattern body aligns stem and seat at 45 deg to minimize pressure drop, while angle pattern eliminates 90 deg elbows in compact piping modules.

• Best For: High-velocity acid lines, slurry streams, and space-restricted offshore skids.

Primary Industrial Applications

• Offshore Oil & Gas (FPSO & Subsea): Topside seawater injection control, firewater deluge regulation, produced water skids, and subsea manifold throttling.

• Sour Oil & Gas (H2S / CO2): Downhole sour gas piping, gas treatment skids, and sour crude refining in compliance with NACE MR0175 / ISO 15156.

• Chemical & Petrochemical Processing: Handling mixed organic/inorganic acids, wet chloride gases, phosphoric acid manufacturing, and solvent recovery loops.

• Flue Gas Desulfurization (FGD) & Power Plants: Absorber tower mist regulation, severe acid scrubbers, and high-temperature exhaust controls.

Quality Assurance, Testing & Certification

Every Falcon Inconel 625 Globe Valve undergoes strict metallurgical verification and non-destructive examination prior to dispatch:
