Ideal for both competition and street
applications, they are similar in material and design to 's competition valves,
but manufactured in large production runs for all of the most
popular applications. Because of the fully automated (robotic)
production, SEV-series valves are priced lower than racing models,
yet feature the same premium quality stainless steel forgings,
chrome stems, stellite tips, under cut stems and swirl-polishing.
Color the SEV Portflow valves economical. If you
do not see a valve you need in the Competition or Silver Line
Series, use the Portflow, as they are suitable for these applications.
