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 SUCTION VALVE SEAT is manufactured from premium wear-resistant alloy materials and precision-machined to provide an accurate sealing surface for the inlet valve. It is designed to maintain proper valve alignment and ensure airtight sealing during engine operation, allowing efficient intake air flow into the combustion chamber. The valve seat is engineered to withstand repeated valve impacts, temperature fluctuations, vibration, and continuous operation in marine environments. Its durable construction helps maintain compression efficiency, improve combustion performance, reduce valve wear, and extend engine service life. This component is suitable for YANMAR N21, 6N21, and 8N21 marine propulsion engines and diesel generator sets
