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.
