Supertech Performance HEVN-200F Supertech Valves
Supertech uses over 20 years of manufacturing experience to
design and produce their Valves. Intensive testing and working
closely with engine builders provides continuous improvements and
provides the market with the best possible product for every
application. High flow rate, durability and quality are all of
Supertech understands that each motor is unique in its
requirement and demands. There fore Supertech offers valves in a
range of materials to suit any motor.
- Stainless ? Made as a one piece forged valve for higher
strength and reliability. Supertech uses mostly EV8 (21-4N) for Intake and Exhaust Valves, however
there are other alloys that are used with different heat treatments
to manufacture Valves for specific applications.
To address the issue of high heat, Supertech uses two different
types of coatings:
Chrome Coating ? Widely used in performance valves
Black Nitride ? This is a hardening treatment that provides a
smooth surface then chromed valves and produces less friction
between stem and guide.
- Inconel 751 ? Nickel Base Alloy ? Nickel base alloy is used for
exhaust valves that reach very high temperatures, such as those in
turbo or supercharged applications.
Supertech Valves are sold Per Valve. For
Example, when order for a Model that requires 16 Valves, order
