Valve seat is one of the most significant components for most valves. The valve seat refers to the surface against which intake and exhaust valves rest when they are closed. Actually, it is a very critical component in the operation of a combustion engine. If it is not properly positioned, oriented, or formed during manufacturing valve leaking will occur, resulting in a loss of compression, even the unpleasant industrial accidents.
Peek Valve seats are usually formed by first press-fitting a cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each valve stem position, and then machining several conical-section valve seat surfaces to form the valve seat into a shape that will match the mating surface of the valve.
