High Strength Marine Exhaust Valve

The Exhaust Valve is a critical component used in internal combustion engines to control the expulsion of exhaust gases from the combustion chamber. Designed for high-performance applications, it is engineered to withstand extreme temperatures, pressure variations, and chemical exposure while ensuring optimal engine efficiency and reliability.

The valve’s design includes precise sealing surfaces that facilitate proper valve seating and gas flow, helping to maintain engine efficiency, reduce emissions, and improve overall performance. Exhaust valves are available in various sizes and configurations, suitable for different engine types and specifications.

Coating materials: Ni, Co-based alloy powder, tungsten carbide powder, etc.
Process method: vacuum remelting surfacing, flame spraying
Our company adds high alloy elements to the original parent material and adopts vacuum remelting surfacing or thermal spraying technology to ensure that the high-temperature resistant alloy of the valve surface surfacing is fused with the parent material, without pores, slag inclusions, looseness, and other welding defects. High-temperature rolling can easily change the surfacing metallographic structure, making it more compact and refined, with higher hardness, greatly improving the high-temperature resistance and corrosion resistance.
