Supertech Performance BMEVN-1030S Exhaust Valve Single Groove Stainless Steel - EV8

The Supertech Performance BMEVN-1030S is a high-performance exhaust valve engineered for demanding applications where durability and flow are critical. This single-groove valve is precision-manufactured using over 20 years of valve production expertise and continuous testing with professional engine builders.

Construction and Materials:

• One-piece forged stainless steel construction for maximum strength and reliability
• Manufactured from EV8 (21-4N) stainless alloy with application-specific heat treatment
• Single-groove design for secure keeper retention
• Engineered for high flow rates without sacrificing durability

Coating Options:

Supertech valves are available with performance coatings to address high-temperature operation and reduce friction. Chrome coating is widely used in performance applications, while Black Nitride treatment provides a hardened, ultra-smooth surface that reduces stem-to-guide friction more effectively than chrome.

Application Notes:

Supertech offers valves in multiple materials to suit different engine requirements. For extreme high-temperature applications such as turbocharged or supercharged engines, Inconel 751 nickel-base alloy exhaust valves are available. This valve is designed to meet the specific demands of your engine build.

Please Note: Supertech valves are sold individually. When ordering for an engine requiring multiple valves, adjust quantity accordingly.
