Description

Constructed from Inconel-Nimonic alloy, these valves offer reduced head temperatures and improved material strength. They feature a single groove, a back-cut angle, and an undercut stem for enhanced performance.

The valves have a head diameter of 31.50mm (+0.5) and a stem diameter of 5.45mm. The "Superfinish" valve stem provides a surface roughness significantly lower than regular valves, contributing to better guide life. Each valve is a one-piece forged design with a magnetic friction-welded wafer, hardened to 52 HRC minimum.
