Valve & Guide & Seat

Valve: A valve is a mechanical component in an engine that controls the flow of gases (air, fuel, exhaust) in and out of the combustion chamber. The intake valve allows the air-fuel mixture to enter, while the exhaust valve lets the exhaust gases exit. Valves are critical for engine performance, efficiency, and emissions control.

Valve Guide: A valve guide is a cylindrical sleeve that ensures the valve moves up and down in a precise, controlled manner. It prevents the valve from shifting out of alignment during operation, ensuring consistent sealing and efficient combustion.

Valve Seat: The valve seat is the surface where the valve makes contact to form a seal when closed. It is typically made of hard materials to resist wear and ensure proper compression in the combustion chamber. The valve seat helps maintain engine efficiency by providing a tight seal and optimizing airflow.
