Engine Valve

The material of "Engine Valve" is heat-resisting stainless steel (JIS-SUH3, SUH35, SUH36). These engine valves possess high strength, anti-wear, anti-corrosion and hear-resisting. The material of engine valve have to be forged with the finest steel, process and flat surface grinding of high precision.Valve GuideThe material of Valve Guide is cast iron & bronze alloy. The material of cast iron (FC-30 or FC-25), the hardness reaches HRB92-102, anti-wear and heat-resisting. The material of bronze alloy (Aluminum bronze & Phosphor bronze), the hardness reaches HRB85-95, long-wearing and heat-resisting. These features reduce the wear of engine valve. The processing of valve guide shall be adopted with CNC computer automatic lathe to ensure that quality of the products reached the standard of O.E.M and used by all kind of engine.Valve Seat
