DuPont™ Kalrez® 0090: High-Performance Sealing for Ball Valves in Refineries
In refinery operations, ball valves play a vital role in shut-off applications. These valves operate in harsh chemical environments, especially sour gas and under high pressure. Standard sealing materials like conventional FFKM often degrade quickly, lasting only 6 to 12 months before failure.
Kalrez® 0090 is a high performance perfluoroelastomer O-ring developed by DuPont™ to meet these challenges. It offers a robust sealing solution with superior chemical resistance and exceptional performance under Rapid Gas Decompression (RGD) conditions.
Typical Application Conditions
- Chemicals: Sour feed gas (5–15% H₂S, 2–5% CO₂)
- Temperature range: 19°F to 250°F
- Pressure range: 1030 psi to 1233 psi
- Current industry practice: Competitive FFKM seals failing within 6–12 months
Why Kalrez® 0090?
- Complies with TOTAL and NORSOK standards
- Demonstrates excellent RGD resistance
- Offers outstanding durability in harsh chemical environments
- Shows minimal to no seal degradation in field applications
