Introducing our premium race valves, meticulously crafted for high-performance applications. The manufacturing process begins with a one-piece forging, where the valve head undergoes a slow, two-step forging process to ensure optimal material flow and integrity.

Following the forging, each valve is precision-machined using advanced CNC technology through multiple stages, guaranteeing exact final dimensions that meet the rigorous demands of racing environments.

To enhance durability, we implement a specialized thermal treatment for relaxation, followed by a nitride curing or coating process tailored to specific applications. This ensures that our valves can withstand extreme conditions while maintaining their structural integrity.

Our commitment to quality continues with an additional grinding process, culminating in a patented surface finish that eliminates imperfections and ensures precise dimensions. Each valve is designed with a focus on maximizing durability, featuring enhanced resistance to fatigue and superior tensile strength.

Each valve tip is hardened to exceed 52 HRc, providing exceptional performance under pressure.

When it comes to dimensional tolerances, our Supertech valves stand out in the market, offering precision that is hard to match. Pair these valves with our ready-to-install valve seats, which also adhere to strict tolerances, and you will experience unparalleled sealing, enhanced performance, and effortless installation.

Our innovative Superfinish coating, combined with black nitrogen treatment, significantly reduces surface roughness to one-third of that found on traditional chromed valves, resulting in smoother operation and improved efficiency.

The end result is a product that delivers unmatched performance and durability, making it the ideal choice for serious automotive enthusiasts.
