SUPERTECH valves start life as a forging, which is then CNC machined for the closest possible accuracy. They are heat treated, the treatment varying with the intended use of the valve, then ground again in a super-finishing process. SUPERTECH valves are inspected by several methods, including ultrasound, X-ray and laser measurement.

For more than three decades SUPERTECH has worked to find the most suitable material for each valve and each application, in order to improve reliability. Hence the different valve materials: stainless steel, INCONEL, titanium and sodium, the latter being contained in the valve stem to improve heat dissipation.

The manufacturing processes of FERREA Racing Components valves are close to those of SUPERTECH: slow two-stage forging, heat treatment and 48-hour stress relieving, then CNC machining. These valves are designed for better reliability in all conditions and also for improved flow, thanks to a thinner stem where it meets the valve head (Superflow Valve). FERREA develops several ranges and materials of valves in order to match as closely as possible the demands of each engine and each application: naturally aspirated, turbocharged or nitrous builds.
