Hastelloy Ball Valves

Premium Hastelloy® Ball Valves | Falcon Valves & Flanges Pvt. Ltd. The Ultimate Defense Against Severe Corrosion, High Temperatures, and Acid Chlorides.

When industrial processes push standard materials past their breaking point, Falcon Valves & Flanges Pvt. Ltd. delivers absolute reliability with our specialized range of Forged and Cast Hastelloy Ball Valves. Engineered to thrive where other alloys rapidly degrade, Falcon Hastelloy valves provide unmatched resistance to highly aggressive reducing and oxidizing chemical streams.

If your system handles raw chemical cocktails, hot mineral acids, or volatile process chemistry, Falcon is your trusted severe-service partner.

📋 Material Grades & Applications

We manufacture our high-performance valves using premium nickel-chromium-molybdenum Hastelloy alloys, tailoring the metallurgy to your precise chemical hazards:

1. Hastelloy C276 (UNS N10276 / ASTM B574 Forged / ASTM A494 Gr. CW12MW Cast)

• The Industry Standard: The most versatile corrosion-resistant alloy available today.

• Major Applications: Exceptional resistance to wet chlorine gas, hypochlorites, chlorine dioxide, ferric/cupric chlorides, and aggressive flue-gas desulfurization (FGD) systems.

2. Hastelloy C22 (UNS N06022 / ASTM A494 Gr. CX2MW Cast)

• Enhanced Protection: Offers even better overall corrosion resistance than C276 in pitting, crevice corrosion, and severe oxidizing environments.

• Major Applications: Pharmaceutical chemical synthesis, waste-water treatment, and high-purity chemical processing lines.

3. Hastelloy B2 / B3 (UNS N10665 / N10675)

• The Acid Specialist: Specifically formulated to master pure reducing acids.

• Major Applications: Unsurpassed resistance to all concentrations and temperatures of Hydrochloric Acid (HCl), as well as pure Sulfuric and Phosphoric acids.

✨ Advanced Design & Operational Features

• Zero-Porosity Grain Boundaries: Our forged line utilizes ASTM B574 bar stock, ensuring structural integrity that completely eliminates the risk of pinhole leaks under high pressures.

• High-Bright Mirror Polish Options: Internal balls and seating areas can be ultra-polished to lower torque demands, prevent media crystallization buildup, and drastically increase seal life.

• Built-in Plant Safety: Includes a certified Fire-Safe design (API 607 / ISO 10497), an anti-blowout stem for over-pressure protection, and an anti-static grounding device as standard.

• Environmental Sealing: Live-loaded chevron stem packing ensures compliance with ISO 15848-1 Fugitive Emissions standards, keeping hazardous VOCs tightly contained.

• Automation Ready: Designed with integrated ISO 5211 mounting pads for quick adaptation to pneumatic, electric, or hydraulic actuators.
