Hastelloy C276 Globe Valves

At Falcon, we design and manufacture high-precision Hastelloy C-276 Globe Valves engineered for critical flow throttling, fine regulation, and positive isolation in severe chemical environments. Cast in high-purity ASTM A494 Grade CW12MW (Cast Hastelloy C-276) and forged from ASTM B574 UNS N10276, our globe valves deliver superior resistance to severe oxidizing agents, hot contaminated mineral acids, wet chlorine gas, and aggressive pitting media.

• Exceptional Throttling & Flow Control: Engineered with optimized globe flow paths and precision-ground parabolic or needle-plug discs for accurate flow regulation without seat wash or erosion.

• Unmatched Severe Corrosion Resistance: High molybdenum and chromium matrix with added tungsten provides total immunity to wet chlorine gas, hypochlorites, chlorine dioxide, ferric/cupric chlorides, and hot organic/inorganic acids.

• Pitting & Crevice Corrosion Protection: Outstanding resistance to localized pitting and stress-corrosion cracking in high-chloride process media.

• Anti-Galling OS&Y Stem Design: Outside Screw & Yoke (OS&Y) layout keeps stem threads outside the wetted process area, preventing thread binding and acid corrosion.

• Certified Low Fugitive Emissions: ISO 15848-1 and API 622 certified packing gland systems ensure zero leakage when controlling toxic, volatile, or lethal chemical lines.

• Standard T-Pattern (Z-Body) Globe Valves:

  • Design: Traditional design for general flow throttling and positive shut-off.

  • Best For: Process lines where precise control is required and pressure drop across the valve is acceptable.

• Y-Pattern (Oblique) Globe Valves:

  • Design: Stem and seat are angled at 45 to the pipeline, creating a near-straight flow path.

  • Best For: High-pressure throttling with significantly reduced pressure drop and turbulence.

• Angle-Pattern Globe Valves:

  • Design: Inlet and outlet ports set at a 90 angle, functioning as both a control valve and a 90 pipe elbow.

  • Best For: Slurry or aggressive chemical lines requiring directional changes without additional fittings.

• Bellows-Sealed Hastelloy Globe Valves:

• Design: Uses a welded Hastelloy metallic bellows stem seal to form a hermetic barrier.

• Best For: Zero-fugitive-emission containment for lethal, toxic, or highly volatile media.

• Seating & Leakage Performance

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

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