Key Information

The valve seat is essential for maintaining the combustion chamber's integrity. It ensures that the intake valve seals tightly, which is necessary for proper compression and efficient engine performance.

As the intake valve opens and closes thousands of times per minute, the valve seat absorbs the repeated impact and extreme heat. It is manufactured from hardened alloys to resist "pitting" or "burning," which can occur under the high pressures and temperatures characteristic of diesel engine operation.
