Portflow Series

SI Valves

Ideal for both competition and street applications, they are similar in material and design to SI'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 and swirl-polishing. 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.

Quicksilvers feature increased undercut stems and thicker margins for increased flow and performance.
