Product Description
Product Introduction
-
Structure: A precision-machined, circular ring made from high-temperature, wear-resistant alloy steel (often containing nickel and chromium). It is engineered for a press-fit installation into the cylinder head, with a smooth, hardened sealing face.
-
Performance: Withstands extreme exhaust gas temperatures (often exceeding 800°C) and the repeated impact of the exhaust valve closing. The hardened alloy surface resists wear, corrosion, and deformation, ensuring a tight seal for thousands of operating hours.
Core Function
-
Sealing the Combustion Chamber: Provides a durable, heat-resistant seating surface for the exhaust valve, ensuring a tight seal to prevent compression loss and exhaust gas leakage.
-
Heat Dissipation: Transfers heat from the exhaust valve to the cylinder head, protecting both components from overheating and deformation.
-
Wear Resistance: The high-alloy construction resists erosion from hot exhaust gases and mechanical wear from the valve, extending the service life of both the seat ring and the exhaust valve.
