Race-engine valves are now even lighter, thanks to the release of Ferrea‘s new hollow-stem titanium valves.

“They’re for high-end applications, like Pro Stock drag racing and some circle track engines,” says Ferrea’s director of marketing, Zeke Urrutia.

All hollow-stem titanium valves will be custom ordered and produced, and they’re available with valve stems ranging from 6mm up to 11/32-inch.

“They’re all one-offs to the customer’s specifications,” adds Urrutia, noting that Ferrea has developed a proprietary manufacturing process that gun drills and micro polishes the bore of the valve stem. Urrutia also says this process ensures structural integrity while reducing the weight approximately 10 percent over a conventional titanium valve.

“The gun drill process also leaves a radius at the ends instead of a square edge,” continues Urrutia. “This reduces the chances of hairline cracks starting.”

Customers can specify that the gun drilling end just before the undercut or extend all the way to the neck of the valve. Other features include CrN coating throughout the valve, hardened tips and radial grooves. The valves can also be ordered in either Superflow (undercut) or conventional design.

Ferrea manufactures these competition valves by forging a special high-temperature titanium and silicone alloy, then each valve undergoes an extensive heat-treat and stress-relief process. Finally, Ferrea says it offers the fastest turnaround times in the industry.
