Weichai WP12NG WP13NG Diesel Engine Exhaust Valve Seat Ring 612650040023 Exhaust Valve Seat for Shacman Delong Sinotruk HOWO Truck

Material Composition: The 612650040023 exhaust valve seat ring is made of a high-temperature resistant alloy capable of withstanding the intense heat of exhaust gases. It offers excellent impact and wear resistance and it is not prone to structural collapse.

Precision Fit: Manufactured with precise dimensions, the component fits securely into the cylinder head bore, ensuring stability during operation and preventing loosening or detachment.

Effective Heat Dissipation: The tight fit between the exhaust valve seat and the cylinder head facilitates heat transfer from the exhaust valve, thereby lowering the valve's operating temperature.

Prevention of Valve Recession: Specifically designed for heavy-duty gas engines, it effectively resists common valve recession issues, ensuring proper valve closure and preventing component damage caused by high-temperature gas leakage.
