Forged ASTM B564 UNS N04400 Monel Globe Valves

Falcon UNS N04400 (Monel 400) forged globe valves are specifically engineered for high-precision throttling and flow regulation in environments where seawater or hydrofluoric acid would rapidly degrade standard alloys. While ball valves are excellent for quick isolation, the Falcon globe valve is the "workhorse" for controlling the flow rate and pressure with extreme accuracy.

Falcon globe valves are designed to provide superior control under high-pressure differentials.

• Plug-Type Disc: Features a heavy-duty, tapered disc that allows for fine-tuned throttling. The disc and seat are precision-lapped to ensure a bubble-tight shutoff when closed.

• Outside Screw & Yoke (OS&Y): The rising stem design keeps the actuator threads outside the flow stream, protecting them from the corrosive "reducing" media typical of Monel applications.

• Integral Backseat: Allows the stem packing to be replaced while the valve is under full pressure, ensuring maximum safety and system uptime.

• Forged Structural Integrity: By using ASTM B564 forgings, Falcon eliminates the risk of "hot shortness" or internal casting defects, ensuring the valve body can withstand high-velocity fluid impact.

• Nickel-Copper Strength: The 63% Nickel and 30% Copper composition of Monel 400 provides a unique blend of high strength and excellent weldability.

   

   

• Erosion Resistance: Globe valves often face high-velocity flow at the seat. Falcon uses Monel K-500 for the stem and internal trim to provide extra hardness and resistance to "wire-drawing" (erosive wear).

• Titanium-Stabilized Forging: Our forging process ensures the material retains its ductility and corrosion resistance even at sub-zero or elevated temperatures.

Each Falcon globe valve is subjected to a comprehensive testing regime:

• Hydrostatic Testing (API 598): Every valve undergoes a shell test at 1.5x the pressure rating and a seat test at 1.1x.

• HF Acid Service Cleaning: For refinery applications, valves are meticulously cleaned and dried to prevent any reaction between residual oils and hydrofluoric acid.

• PMI (Positive Material Identification): 100% verification of all pressure-retaining parts to ensure the chemical signature matches UNS N04400.

• Dimensional Precision: Machined on high-precision CNC centers to ensure a perfect fit for the bolted bonnet and gasket.

• Marine Engineering: Controlling seawater flow in fire-main systems and heat exchangers.

• HF Alkylation Units: Precision throttling of hydrofluoric acid in oil refineries.

• Salt Production: Regulating the flow of boiling brine and salt slurries.

• Chemical Processing: Handling non-oxidizing chlorides and caustic solutions.

Falcon's expertise lies in understanding the metallurgical behavior of Monel. We ensure that our forging process avoids the "hot-shortness" (brittleness during forging) that often plagues lower-quality manufacturers, resulting in a valve that is as tough as the environment it serves.

While the standard globe valve is a powerhouse,Falcon leverages the unique properties of Monel 400 (UNS N04400) to manufacture specialized configurations for "Extreme Service" applications. Because Monel is both highly ductile and resistant to specific acids, it allows for designs that standard stainless steel cannot support.
