SINGLE VALVE

Don't build your engine with inferior parts! Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitride which is most popular in European and Japanese motors.

Supertech High Performance Race Engine Valves features:

- The micro-hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitride layer (micro-hardness is 800HV minimum).
- Surface finish is smoother than with chromed stems, having less friction between stem and guide.
- Valve seat surface is harder with the nitride layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes.
- Matches any kind of seats (Nodular iron seats, steel powder metal seats, hard aluminium-copper seats or beryllium copper seats).
- Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
- The nitride layer is adhered to the base material at a microscopic level, so does not "flake" or brake when the valves bend due to impacts with the pistons.
- The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.
