Engine Valve Core Manufacturing Process and Advantages

The Renault K4M engine is widely used in models such as the Renault Megane, Scenic, and Dacia Logan/Duster. Operating under demanding conditions, it places extremely high requirements on the heat and wear resistance of its valves.
Intake valves: Manufactured from high-quality, wear-resistant alloy steel such as 40Cr to ensure resistance to wear under ambient temperatures and high-velocity intake flow.
Exhaust valves: Strictly manufactured from 21-4N austenitic heat-resistant steel, capable of withstanding the thermal fatigue and oxidative corrosion associated with high-load, high-temperature exhaust environments, thereby preventing valve burning or recession.

Precision Friction Welding and Surface Treatment
Utilizes an advanced bimetallic friction welding process to seamlessly join the valve stem and head, ensuring structural integrity.
The valve seating face undergoes specialized hardening treatments to effectively enhance impact resistance and sealing durability.

Strict Dimensional Tolerance Control
Stem diameter, head diameter, and overall length are manufactured in strict accordance with OE drawing tolerances, ensuring a perfect match with Renault OE valve guides and valve stem seals, thereby preventing abnormal oil consumption and valve leakage.
