- Valve sheets maintain airtightness with the valves and generally require wear resistance. - With the engine under high load, the cooling performance of the valve sheets becomes important and is greatly concerned with high engine outputs. - To efficiently transfer the heat away from the valve sheets, these Bery Rings must be a copper alloy since copper has a high thermal conductivity. - Tomei Bery Rings are made of beryllium copper alloy which can reduce the heat of valve sheets by transferring the heat to the cylinder head under extreme engine conditions.
