MAN & B&W series 6L45GFCA Engine valve seat insert

Valve seats are a critical engine component because they are the foundation of the valve train. The seats provide a surface for the valves to seal against when they close so there's no loss of compression or pressure from the combustion chamber. The seats also help cool the valves by conducting heat away from valves into the cylinder head. The seats also support the valves and determine installed valve height, which affects valvetrain geometry and valve lash. The diameter of the seats and the contour of the angles that are machined into the face of the seats also limit how much air the engine can flow at any given valve lift and rpm.

Inexpensive engines may have valve seats that are simply cut into the material of the cylinder head or engine block (depending on the design of the engine). Some newer engines have valve seats that are sprayed on rather than being pressed into the head, allowing them to be thinner, creating more efficient transfer of heat through the valve seats, and enabling the valve stems to function at a lower temperature, thus allowing the valve stems (and other parts of the valvetrain) to be thinner and lighter.
