Dissimilar material bonding of drive shaft with flow control component of valve

摘要

A valve, in certain embodiments, includes a drive shaft (62) configured to couple to a fluid control component and having an interlace material (82) at the joint between the drive shaft and the fluid control component. A valve, in other embodiments, includes a fluid control component configured to receive a drive- shaft and having an interlace material at the joint between the fluid control component and the drive shaft. A valve, in further embodiments, includes a drive shaft having a mechanical locking system (80) and a fluid control component coupled to the drive shaft at a joint, wherein the spline (80) aids in coupling the fluid control component to the drive shaft.
