Hastelloy Pressure Safety Valves

Falcon Hastelloy Safety Valves

The Gold Standard for Corrosive Pressure Management

Falcon’s Hastelloy Safety Valves are the definitive solution for high-stakes environments where material failure is not an option. Specifically engineered for the chemical, pharmaceutical, and offshore industries, these valves provide failsafe pressure relief in the presence of the most aggressive media.

Material Superiority: Hastelloy C-Series

While standard alloys succumb to pitting and oxidation, Falcon utilizes high-grade Hastelloy (Nickel-Molybdenum-Chromium) to ensure your systems remain secure. This material choice offers:

• Total Acid Resistance: Unmatched performance against sulfuric, phosphoric, and nitric acids.

• High-Temperature Strength: Retains mechanical properties in thermal environments that would soften or degrade lesser metals.

• Crevice Corrosion Protection: Designed to eliminate localized corrosion in stagnant zones or joints.

Performance Engineering

• Instantaneous Response: Falcon's precision-wound spring technology ensures the valve lifts at the exact set pressure, every time.

• Zero-Leak Technology: Features a high-tolerance disc and seat finish to provide a bubble-tight seal, preventing hazardous fugitive emissions.

• Ease of Maintenance: The modular internal design allows for streamlined inspection and parts replacement, reducing system downtime.

• Compact Footprint: Engineered to provide maximum flow capacity (coefficient of discharge) while maintaining a space-saving profile.

Technical Applications

• Aggressive Chemical Processing: Ideal for reactors, storage tanks, and piping systems.

• Offshore Platforms: Resistant to the harsh, saline-heavy atmospheres of maritime environments.

• Desalination Plants: Handles high-chloride fluids without structural degradation.

Engineering Standards & Compliance

Technical Summary Table

Material Grade Specification Table

Falcon safety valves are available in a variety of Hastelloy grades to match your specific chemical compatibility and pressure requirements.

Understanding the Grades for Your applications

• Forged (ASTM B564): Recommended for Critical High-Pressure components and valves typically sized 2" and below. Forging provides a refined grain structure that increases impact resistance and fatigue life.

• Cast (ASTM A494): The industry standard for Large Orifice valve bodies (size 3" to 12"+). Modern casting techniques at Falcon ensure high integrity and compliance with API 526 dimensional requirements.

Component-Level Material Selection

For a complete safety valve assembly, we ensure material harmony across all wetted parts:

1. Body/Bonnet: Cast or Forged Hastelloy as per the table above.

2. Nozzle & Disc: Always manufactured from forged/bar stock Hastelloy to ensure the highest hardness and seat integrity.

3. Bellows: High-flexibility Hastelloy C276 is used as standard to protect the spring from corrosive discharge
