Ball Valves

Material Capabilities: Engineered for Extremes

At Falcon, we specialize in manufacturing Floating and Trunnion Mounted Ball Valves that withstand the most demanding environments. From standard industrial applications to highly corrosive and high-pressure service (up to Class 2500#), our foundry and sourcing capabilities cover the complete spectrum of metallurgy.

Below is a brief guide to the material grades we offer:

1. Carbon Steel (Standard Service)

The backbone of the valve industry, offering excellent strength and durability for general applications.

• WCB / A105: The industry standard for non-corrosive flow at moderate temperatures. Ideal for water, oil, and gas transmission.

• Low-Temperature Carbon Steel (LCC / LCB / LF2): Specifically heat-treated to maintain impact toughness in sub-zero environments, essential for cryogenic and northern climate applications.

2. Stainless Steel (Corrosion Resistance)

Designed for clean services and environments requiring resistance to oxidation and chemical attack.

• Austenitic Stainless (CF8/304, CF8M/316, CF3M/316L): Provides excellent resistance to general corrosion and pitting. Widely used in chemical processing, food & beverage, and pharmaceutical sectors.

• Stabilized Grades (321, 347): Alloyed with Titanium or Niobium to prevent intergranular corrosion at elevated temperatures.

3. Duplex & Super Duplex (High Strength & Durability)

Bridging the gap between standard stainless and high-nickel alloys, these materials offer superior strength and resistance to Stress Corrosion Cracking (SCC).

• Duplex (2205 / CD3MN): Offers twice the strength of standard stainless steel with excellent resistance to chloride environments.

• Super Duplex (2507 / CE3MN): Designed for highly aggressive conditions, such as offshore oil & gas platforms and desalination plants, where pitting and crevice corrosion are major concerns.

4. Alloy Steel (High Temperature & Pressure)

Formulated to withstand extreme heat and pressure cycles without deforming or failing.

• Chrome-Moly Steels (WC6, WC9, C5, C12): These grades maintain high creep strength at elevated temperatures, making them the preferred choice for power generation and high-temperature refinery processes.

5. Nickel Alloys (Severe Service)

When standard steels fail, Nickel alloys provide the ultimate protection against extreme heat, oxidation, and aggressive acids.

• Inconel (600, 625, 718, 825): Exceptional strength and oxidation resistance at extreme temperatures.

• Monel (400, K500): Renowned for its resistance to rapidly flowing brackish water or seawater and hydrofluoric acid.

• Hastelloy (C276, C22): The premier choice for the most severe chemical environments, offering unmatched resistance to pitting and stress corrosion cracking in sour gas and acid services.

6. Exotic & Reactive Metals (Specialty Applications)

Falcon prides itself on manufacturing valves from materials that are difficult to source and machine.

• Titanium (Grades 2, 5, 12): Incredible strength-to-weight ratio and immunity to seawater corrosion. Vital for aerospace, marine, and chlor-alkali industries.

• Zirconium: Offers unique resistance to highly corrosive acids (hydrochloric, sulfuric, acetic) where even stainless steel and nickel alloys dissolve.

7. Special & Custom Grades

We specialize in the "hard-to-get." If your project requires a specific, non-standard metallurgy not listed here, Falcon has the supply chain and engineering expertise to manufacture it to your exact specifications.

Why Choose Falcon Materials?
