Valve

Valves are critical components within the engine's valve train, responsible for controlling the flow of air and fuel into the combustion chamber and exhaust gases out. Located in the cylinder head (Engine Parts > Heads & Valve Train), these parts ensure proper engine timing and efficient performance in passenger cars and commercial vehicles. Valves operate in conjunction with other valve train components like camshafts, lifters, and springs to open and close at precise intervals. They are typically constructed from high-strength alloys to withstand extreme temperatures and pressures. Examples include intake and exhaust valves like MAHLE MPN 037VE31408000, MAHLE MPN 209VA31297000, and MAHLE MPN 037VA31089000. Proper valve function is essential for maintaining engine compression, power output, and emissions control.
