WESPC Valve Seat T400755 for Perkins 1506A E88TAG 1104 1004 Series - 46.0mm OD, 45° Seat Angle

This intake valve seat ring is engineered for Perkins 1506A/E88TAG and 1104/1004 series 4- and 6-cylinder diesel engines (4.4L & 8.8L displacement). It serves critical applications in 60Hz prime generators, combine harvesters, MF 6400-series tractors, and marine auxiliary sets rated 150-250 kW. The component ensures volumetric efficiency above 92% at 2,800 RPM while meeting EU Stage IIIA emission standards.

Manufactured from low-carbon steel (0.15% carbon content) that undergoes copper infiltration and sintering to achieve 7.2 g/cm³ density. This process delivers 350 HB hardness and thermal conductivity of 45 W/m·K for efficient heat dissipation. The copper-infiltrated matrix prevents valve micro-welding and maintains seat temperatures below 220°C even with 60°C inlet air.

• Surface finish: 0.25 µm Ra for optimal bedding
• Break-in period: 50 hours
