Engine Pro Introduces New Nitro Black Valve
New product makes nitrided valves available for domestic racing engines. The Engine Pro Nitro Black valves are manufactured using a five-step proprietary liquid nitriding process that treats the entire valve, enhancing the strength of the complete piece, not just the wear characteristics of the stem.
Engine Pro has launched its new series of high-performance engine valves called Nitro Black.
According to Engine Pro’s Product Manager Don Weber, the valve was
developed to fill a big void in the market. “Up until now, this type of
valve was only available for four- and five-valve racing engine
applications,” Weber said. “Our Nitro Black product now makes these
high-tech valves available for two-valve domestic racing engines.”
Weber added that the Nitro Black valves look great in the box, but the
real appeal is their superior performance characteristics not found in
traditional chrome-plated valves.
The Engine Pro Nitro Black valves are manufactured using a five-step
proprietary liquid nitriding process that treats the entire valve,
enhancing the strength of the complete piece, not just the wear
characteristics of the stem. Nitriding is not a coating and doesn’t
change the dimensions of the valve but actually penetrates the valve
enhancing its strength.
“We conducted rotating-bending fatigue tests which showed that our deep
nitriding process provides much better ductility under the hard
nitrided layer,” Weber noted. “That makes the valve less likely to
break even if it comes into contact with the piston under extreme
conditions.” Weber says the valve’s harder, smoother surface also
reduces crack initiation.
According to Weber, Nitro Black valves hold their performance
characteristics longer in engines using exotic, oxygenated and race
fuels including alcohols because the nitriding process makes them
better able to resist corrosion and deposits.
For those who are concerned about the impact of automobile racing on
the environment, Weber points out that Engine Pro's nitriding process
is much cleaner than chroming and produces zero effluent at the plant.
Engine Pro’s Nitro Black engine valves are now available to engine
builders and jobbers through its nationwide network of distributors.
