Product Summary

All Supertech stainless steel intake valves begin with a one piece forging, the valve head undergoes 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 receives one final grinding, followed by Supertech's patented Super finishing of the entire surface. This ensures each valve is free of any imperfections and the dimensions are precise.

NITRIDE COATING

Supertech's Black Nitride Coating is a hardening treatment adhered to the base material at a microscopic level.  The micro hardness is higher than the underlying stainless steel material, this 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. 

OVERSIZED VALVE OPTION

Supertech Valves are available in either stock replacement standard size, or +1mm oversized valve head diameter.  Oversized valves require either aftermarket valve seats, or machining to the stock valve seat.  This ensures a perfect seal for the valve head and seat.  The larger diameter also provides an increased skirt area, providing a higher flow at a lower lift.  Oversized valves require machine work to the cylinder head.

SINGLE GROOVE VALVE OPTION

Single groove valves allow for the use of Supertech single groove valve keepers.  Single groove valve keepers grip a larger area of the valve shaft, rather then relying on the traditional three groove material to restrain the valve.  24 Supertech single groove keepers are included with all single groove valves.
