The valve is an important part of the engine. The function of the valve is to be responsible for inputting air into the engine and discharging the exhaust gas after combustion. The material of the valve is usually divided into 40Cr, 4Cr9Si2, 21-4N and 23-8N. Additional processes are usually top surfacing, cone surfacing, surface nitriding treatment, surface chrome plating treatment, etc.
