Product Summary

pdfpdfpdf

A PTFE valve seat which is made from PTFE is the area in an internal combustion engine's cylinder head that the intake and exhaust valve actually contact when the valve is in the closed position. Typically made of a special alloy such as stellite or a tungsten-vanadium compound, the valve seat is commonly pressed into the cylinder head and machined to allow for maximum flow and sealing of the intake and exhaust gasses. Both cast iron and aluminum cylinder heads use a valve seat to provide the proper valve closing and sealing of the combustion chamber. Most valve seat machining consists of multiple angles machined on both the seat and the valve head to create both flow and pressure sealing. Most original equipment engines are designed to run on unleaded or diesel fuel, while the typical performance engine is commonly fueled with unleaded racing gasoline or methanol. Unleaded gasoline does not provide the cushioning effect the leaded fuel provides. This can lead to a valve seat being destroyed by the tremendous forces of the valves being opened and slammed closed. In leaded fuel, the lead is used to cushion this force and provide long-term protection for both the valve and the valve seat. Some engine builders recommend a lead substitute be added to the unleaded fuel to protect the valve train.
