Tungsten carbide flat valve seats are not used in everyday applications due to their cost. They are reserved for the most severe service conditions where standard materials would fail quickly. Key applications include:

• Severe Service Valves: Controlling abrasive slurries in mining, mineral processing, and power generation (e.g., fly ash).

• Oil & Gas Production: Especially in choke valves and Christmas tree valves where well fluids contain sand, proppant, and other erosive particles.

• Chemical Processing: Handling highly corrosive acids, alkalis, and solvents.

• High-Performance Automotive: In racing engines with aggressive cam profiles and high spring pressures, where valve seat recession is a major concern.
