Yanmar YANMAR - N21 -EXHAUST VALVE (NIMONIC) - 147673-11740
The EXHAUST VALVE (NIMONIC) is a high-performance valve train component used in YANMAR marine diesel engines to control the discharge of combustion gases from the cylinder. Manufactured from premium Nimonic heat-resistant alloy, it is designed to withstand extreme exhaust temperatures, high pressures, and continuous heavy-duty operation. The valve ensures reliable sealing, efficient exhaust flow, 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 (NIMONIC) is manufactured from advanced Nimonic nickel-based superalloy specifically developed for high-temperature applications. This material offers exceptional resistance to heat, oxidation, corrosion, and mechanical fatigue, making it ideal for exhaust valve service in marine diesel engines. The valve is precision-machined to ensure accurate seating and sealing while efficiently releasing combustion gases during the exhaust cycle. Engineered to withstand continuous exposure to extreme thermal loads, pressure fluctuations, vibration, and corrosive exhaust environments, the Nimonic exhaust valve helps maintain engine efficiency, reduce valve wear, and extend overhaul intervals. It is suitable for YANMAR N21, 6N21, and 8N21 marine propulsion engines and diesel generator sets operating under severe marine and industrial conditions.
