Yanmar YANMAR - N21 -EXHAUST VALVE SEAT - 147673-11040
The EXHAUST VALVE SEAT is a critical cylinder head component used in YANMAR marine diesel engines to provide a hardened sealing surface for the exhaust valve. It ensures proper valve seating, maintains combustion chamber sealing, and facilitates heat transfer from the exhaust valve to the cylinder head. Designed for high-temperature operation, the valve seat delivers reliable performance and extended service life in demanding marine applications.

ENGINEX MARINE is a well-known supplier of YANMAR marine diesel engine spare parts, covering models such as N18, N21, M200, M220, Z280, N260, N280, N330, HAL, EY18, EY22, EY26, and EY17.
The EXHAUST VALVE SEAT is manufactured from premium heat-resistant alloy materials and precision-machined to provide a durable sealing surface for the exhaust valve. It is designed to withstand extreme combustion temperatures, high mechanical loads, and continuous exposure to hot exhaust gases. The valve seat ensures proper valve alignment and sealing, preventing compression loss while promoting efficient heat dissipation from the valve head to the cylinder head. Its robust construction helps reduce valve wear, maintain engine efficiency, and extend component service life. This component is suitable for YANMAR N21, 6N21, and 8N21 marine propulsion engines and diesel generator sets operating under demanding marine and industrial conditions.
