Supertech Performance HEVT-1022F Exhaust Valve

The Supertech Performance HEVT-1022F is a high-performance exhaust valve engineered for demanding applications. Manufactured with over 20 years of experience, Supertech valves are developed through intensive testing and collaboration with professional engine builders to deliver superior flow rates, exceptional durability, and uncompromising quality.

Construction and Materials:

• One-piece forged stainless steel design for maximum strength and reliability
• Primarily utilizes EV8 (21-4N) alloy with specialized heat treatments for optimal performance
• Available with advanced coating options for extreme temperature applications

Coating Options:

• Chrome Coating: Widely used in performance applications for wear resistance and durability
• Black Nitride: Advanced hardening treatment that creates a smoother surface than chrome, reducing friction between the valve stem and guide for improved performance and longevity

For turbocharged, supercharged, or other extreme high-temperature applications, Supertech also offers Inconel 751 nickel-base alloy valves designed to withstand significantly higher exhaust temperatures.

Important: This valve is sold individually. When ordering for an engine requiring multiple valves, adjust the quantity accordingly (e.g., order quantity of 16 for a 16-valve engine).
