Advanced Material Technology:
The valve seats utilize specialized alloy compositions tailored for their specific locations in the combustion chamber. High-nickel chromium exhaust seat formulations withstand continuous 900°C (1652°F) temperatures while resisting thermal fatigue, while copper-enhanced intake seats optimize heat transfer to maintain stable valve clearances.
Performance Advantages:
-
Extended Service Life – Proprietary alloy blends demonstrate 40-50% greater wear resistance than conventional materials, particularly valuable in high-mileage trucking applications.
-
Precision Thermal Management – The optimized material combinations provide:
-
Superior heat dissipation from critical valve areas
-
Reduced hot spotting in the combustion chamber
-
More consistent valve lash settings
-
-
Engineered Sealing Surfaces – CNC-machined to 0.4-0.6μm Ra surface finish ensures:
