High Temperature Service Valves

Falcon Manufacturing & Design: High-Temperature Flow Control

Falcon Manufacturing specializes in the precision engineering and production of high-temperature valves designed for the most demanding industrial environments. By integrating advanced metallurgy with specialized machining techniques, Falcon ensures peak performance where standard components fail.

Core Competencies & Technical Mastery

Falcon’s reputation is built on its ability to handle "unworkable" materials and achieve microscopic tolerances:

• Stellite™ Specialists: Expertise in applying and machining cobalt-based Stellite alloys. This provides exceptional resistance to wear, galling, and corrosion at extreme temperatures.

• Precision Machining: Utilizing specialized heavy-duty machinery tailored for high-nickel alloys and hardened steels.

• Lapping & Grinding: Advanced finishing processes that ensure bubble-tight seals and metal-to-metal seating, critical for high-pressure safety.

• Custom Engineering: In-house design capabilities to modify valve geometry for specific thermal expansion requirements.

Diverse Valve Portfolio

Falcon produces a wide range of valve types, each optimized for high-heat cycles:

Valve Type	Primary Application	Key Feature
Gate Valves	Isolation in steam/oil lines	Low pressure drop; Stellite-faced seats.
Globe Valves	Throttling and flow regulation	High durability under frequent cycling.
Check Valves	Backflow prevention	Rapid response with heat-resistant springs.
Ball Valves	Quick shut-off (Severe Service)	Metal-seated designs for abrasive media.
Control Valves	Automated process modulation	Precision-ground stems for smooth actuation.

Falcon Manufacturing & Design provides high-integrity sealing solutions across all major industry standards, specifically focusing on metal-seated valves that survive extreme thermal cycling.

Leakage Class Capabilities

Falcon manufactures valves according to ANSI/FCI 70-2 and API 598 standards. Their specialized lapping and grinding processes allow them to achieve superior shut-off even in metal-to-metal configurations:

• Class IV (Standard Industrial): The benchmark for metal-seated valves, allowing a maximum of 0.01% leakage of rated capacity. Ideal for general steam and hydrocarbon service.

• Class V (Critical/High-Pressure): A rigorous standard for high-pressure applications where leakage must be minimal (measured in microliters per inch of orifice). Falcon achieves this through precision Stellite™ seat grinding.

• Class VI (Bubble-Tight): While typically reserved for soft-seated valves, Falcon’s Triple Offset Butterfly Valves and high-precision metal-seated ball valves are engineered to achieve bubble-tight, zero-leakage performance in critical gas and hazardous liquid services.

Material Grades & Metallurgy

Falcon works with an extensive range of materials to ensure chemical compatibility and structural integrity at temperatures ranging from -268°C to 540°C (-450°F to 1000°F).

Material Category	Specific Grades Offered
Hard-Facing (Trim)	Stellite 6, Stellite 12, Stellite 21 (for superior wear/erosion resistance).
Stainless Steel	SS304/L, SS316/L, SS904L, 254 SMO.
Carbon & Alloy Steel	WCB, WCC, LCB, LCC, WC6, WC9, C5, C12.
High-Nickel Alloys	Inconel (600, 625), Hastelloy (B, C276), Monel 400.
Advanced Steels	Duplex and Super Duplex Stainless Steel.
Specialty	Nickel Aluminum Bronze, Titanium, and Alloy 20.

Manufacturing Excellence

• Sealing Technology: Seats are available in Integral, Renewable, or Weld-deposited (Stellite) formats.

• Testing Rigor: Every valve undergoes hydrostatic and pneumatic testing per BS 5146 or API 598 to verify the specified leakage class before dispatch.

• Precision Finishing: Their in-house lapping and grinding machines are specifically designed to handle hard-faced surfaces, ensuring a mirror finish that prevents "wire-drawing" and premature seat failure in high-velocity steam.
