Patent ID: 7032883

Claim:
A flow control valve system comprising: a housing defining a flow path having a long axis, the housing having a seating element disposed substantially perpendicular to the long axis of flow path and the housing having a base defining a guide path, the guide path having a linear path portion and a rotational path portion; a throttle element having a throttle element face oriented substantially within the flow path defined by the housing, the throttle element moveably coupled to the base within the guide path; and a linkage assembly coupled to the throttle element and oriented substantially outside the flow path, the linkage assembly configured to (i) position the throttle element along the linear path portion relative to the seating element, the throttle element face oriented substantially perpendicular to the long axis of the flow path and (ii) rotate the throttle element along the rotational path portion relative to the seating element; wherein the linkage assembly positions the throttle element along the linear path portion of the guide path, relative to the seating element, to meter flow within the flow control valve system; and wherein the linear path portion of the guide path defines a length of approximately one-quarter of a diameter of the seating element.
