- Function: Inlet valves regulate the entry of air, fuel, or other fluids into a system. In engines, they allow the air-fuel mixture to enter the combustion chamber during the intake stroke 46.
- Materials: High-quality materials like chrome-silicon-steel are often used for durability and resistance to wear 8.
- Dimensions: Inlet valves come in various sizes, such as valve head diameters (e.g., 36 mm) and overall lengths (e.g., 105 mm), tailored to specific applications 78.
- Compatibility: These valves are designed for specific vehicles or systems, such as those from Volvo, Mercedes-Benz, Audi, and VW 78.
