Tungsten, alloyed with Chrome, Molybdenum and Vanadium in a tool steel base, creates an extremely strong alloy. This gives Rowe valve seats a greater wear resistance and better ability to withstand higher heat than competitor's seats. Rowe seats can safely operate in excess of 1400° F temperatures. The competition typically loses its hot hardness at or about 1100° F.

Each seat is individually cast using a process that, together with the special alloy, gives greater resistance to oxidation from fuel contaminates, such as sulphur. Unlike other seats, tungsten seats will not cause valve and valve seat "pocketing" and recession.

The Rowe seat has an initial hardness of Rockwell "C" 42 that rises to 50 R/C during the first few hours of running time. The material hardens during this period through the work of heat and valve impact against the seat. This increased hardness greatly reduces seat distortion and extends the life of both the valve and the valve seat.

Rowe seats cut cleanly and easily with existing tooling and will not clog the cutters or stones. These seats can be fitted using the same methods you are familiar with, yet offer a far superior performance. Using Rowe seats will give your customers the best in quality and reliability while providing you with increased profits!
