Two types of protection. One complete solution.
Engine valves face two very different types of stress: extreme combustion heat at the face, and constant friction along the stem. Treating only one leaves the component vulnerable. Our approach combines thermal protection with friction reduction for complete coverage.
For a full valvetrain solution, pair with our valve spring coatings and cylinder head coatings.
Thermal barrier on the face reduces heat transfer and warping.
Low-friction stem coating for smooth guide operation.
Consistent valve-to-seat contact under extreme conditions.
Reduced wear, burning, and material fatigue.
Valve failure is rarely caused by a single factor. Excessive heat can weaken materials and reduce sealing efficiency, while friction within the guide leads to inconsistent movement and wear over time.
Face coating (CBC2): A ceramic thermal barrier applied to the valve face. It reflects combustion heat, reducing the risk of burning, warping, and material fatigue — especially in turbocharged and high-compression engines.
Stem coating (DFL-1): A dry film lubricant on the valve stem. It reduces friction within the guide, improving movement consistency and reducing wear — particularly during cold starts and high-RPM operation.
They experience two different stresses — extreme heat at the face and friction along the stem — each requiring a different type of protection.
It reduces heat transfer from combustion gases, helping the valve operate at more stable temperatures and reducing the risk of burning.
A low-friction coating improves movement within the guide and reduces wear during cold starts and high-RPM operation.
No. They benefit both performance and street applications where heat and friction affect reliability.
Yes. Exhaust valves benefit most from thermal protection, while both intake and exhaust benefit from stem coatings.
