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.
