API 6D / API 608 Metal-Seated Ball Valves - Low Platform
STELLITE METAL-TO-METAL · -29°C TO +425°C · SEVERE SERVICE
Severe-service ball valve with Stellite hard alloy metal-to
metal seating for high-temperature steam, abrasive slurries,
erosive particulate, and H₂S sour gas service. Three body
material options (WCB, CF8, CF8M) cover the full industrial
duty spectrum. API 598 Class IV reliable shutoff from -29°C to
+425°C — outperforms PTFE soft seat in conditions that cause rapid soft-seat degradation.
