DP Performance Series engine valve are manufactured under our strict standards to assure premium quality with closest tolerance and eccentricity levels that are ensured from state of the art cnc machines.

Valve manufacturing process starts with 3D CAD models according to customer needs and engine specs. Years in increased cylinder head flow research can assure the final horse power increase of your engine.

Homologated valves for Rally engines, increased head sizes, reduced stem sizes for weight reduction, different angled heads are some of the applications that our valves can cover.

All valves are made either from forged or billet materials such as steel, inconel or titanium type. Hollow stem valves can also be available on custom ordering. The different alloys available for usage are to enable our customers a choice in order to customize the valve for top performance according to the designated application high engine technical specifications.
