Valve Insert
Cummins®

A valve insert, also known as a valve seat insert, is a component of an internal combustion engine that is responsible for providing a durable and wear-resistant surface for the intake and exhaust valves. It is typically made of a high-strength material such as hardened steel or alloy, and is designed to fit precisely into the cylinder head. The valve insert serves as the contact point between the valve and the cylinder head, ensuring that there is no leakage of gases during operation. Over time, due to wear and tear, the valve insert can become damaged or worn out, leading to reduced engine performance and increased emissions. As such, it is important to regularly inspect and replace worn-out valve inserts in order to maintain optimal engine performance. Valve inserts are commonly used in trucks and other heavy-duty vehicles where reliable operation is critical. Part number 3072318 refers specifically to a particular type of valve insert manufactured by Cummins Inc., one of the leading suppliers of diesel engines for commercial vehicles.
