Our engine valves have significant advantages in quality, which stems from the whole - process control from raw materials to production processes.
High - strength heat - resistant alloys are selected as raw materials, laying a solid foundation for the high - temperature resistance and fatigue - resistance performance of the valves. During the production process, relying on precision CNC machining equipment, precise control of valve dimensional accuracy and form - position tolerances is achieved, ensuring assembly adaptability.
The surface treatment adopts an advanced nitriding process, which not only significantly improves the surface hardness of the valve to meet the high - wear - resistance standard, but also forms a dense protective layer to enhance corrosion resistance.
In summary, our valves, with the advantages of raw materials, equipment and processes, have achieved the core characteristics of high - temperature resistance, corrosion resistance, fatigue resistance and high hardness, and can stably cope with the complex working conditions of the engine.
