Abstract
A linkage mechanism for a valve assembly includes one of a slot and an engagement component operably coupled to at least one drive component and located eccentrically from a rotational axis of the at least one drive component, a link operably coupled to one end of a valve stem of a valve member and being moveable with the valve stem, the link having another one of a slot and an engagement component, and a rotatable lever coupled to at least one housing, the lever including one of a first slot and a first engagement component operably engaged with the one of the slot and the engagement component of the at least one drive component and one of a second slot and a second engagement component operably engaged with the one of the slot and the engagement component of the link, wherein rotation of the at least one drive component causes the lever to rotate to convert a rotational movement of the at least one drive component to a linear movement of the link such that the link, the valve stem, and the valve member are moved axially in a direction along a longitudinal axis of the valve stem.
