HSD has been manufacturing custom engine valves since the early 1980’s.
Machined up from 214n one piece stainless steel forgings ranging in stem sizes from 6mm through to 7/16 in diameter.
Our CNC. Machining Centre enables us to manufacture engine valves to your exact requirements ie: margin width, profile and under head dishing. Each valve has its own special characteristics, for example, the air flow across the back of a valve can vary greatly depending on its shape, either enhancing or detracting in the overall performance of a cylinder head. For this reason we have a vast range of valve profiles to choose from which allows us to supply a valve combination which will best suit your needs.
Our valves usually have an undercut stem, they are swirl polished to eliminate fatigue points due to machining processes and they are tufftrided to enhance wear resistance. However, we will manufacture any engine valve to conform to your desires.
