Production of Supertech valves begins with a one piece forging, where the head of the valve is forged under a slow two step process to keep a good material grain flow. The forging is then CNC machined in several steps to ensure the precision of the final dimensions. Supertech then do another heat treatment for stress relieving followed by a nitride hardening treatment. Lastly, final grinding followed by their patented Superfinishing of the surface to ensure that each valve is free of any imperfections and the dimensions are precise. Supertech applies more than 30 years of experience in the development of each and every racing valve sold. Experience combined with state of the art equipment such as ultrasonic test, x-rays, laser measurement equipment, and applications like computerized finite element analysis.
Intake valves are made exclusively from an enhanced version of EV8 (21-4N) steel. This is the highest grade of steel available and provides the strength to withstand just about any application. Exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Some applications call to harden certain areas such as the tips and or the seats. For these applications Supertech often times weld other hard metal alloys to the valve for increased durability.

Inconel 751 is a nickel base alloy material that is used for exhaust valves in engines that reach very high temperatures and its use is growing with application of turbos and superchargers.
