Zirconium Nitride (ZrN) coating is the ultimate solution for valves that are intended for use in highly corrosive environment.

The Zirconium Nitride coating will substantially reinforce the valve’s corrosion resistance property and enable highly durable valve performance.
The Zirconium Nitride coating will also provide enhancement to the valve’s wear resistance property, significantly increase the valve’s lifespan, and improve the valve stem friction coefficient to allow decreased friction between the stem and the valve guide.

SINUS recommends on Zirconium Nitride coating for valves that are due to perform in extremely high corrosive environment, be it for any kind of engine that outputs such conditions.

The Zirconium Nitride coating is presented in shiny golden white color.
