All Supertech stainless steel intake valves begin with a one piece forging, the valve head undergos a two step forging process for excellent material grain flow. Each valve is then CNC machined to ensure exact final dimensions. Next, another heat treatment and nitride hardening treatment for final stress relieving to ensure valve strength. The valve recieves one final grinding, followed by Supertech's patented Superfinishing of the entire surface. This ensures each valve is free of any imperfections and the dimensions are precise.

Black Nitride Coating
Supertech's Black Nitride Coating is a hardening treatment adhered to the base material at a microscopic level.  The microhardness is higher than the underlying stainless steel material. Tthis keeps excellent ductility throughout the entire valve. Surface finish is smoother causing less friction between stem and guide, while the valve seat surface resulting in longer lasting valve head/seat interface. The Nitride coating is a perfect match for any kind of valve seat such as nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats. The Black Nitride anti-friction properties combat internal power loss due to valve-guide friction at higher engine speeds.
