Abstract
A valve assembly including a plurality of control systems. A member is included that is actuatable by each of the control systems for controlling operation of the valve assembly. A plurality of tangs is included with at least one tang corresponding to each control system. A plurality of windows each having a shoulder is included, each tang disposed in one of the windows and selectively engagable with the shoulder of the one of the windows. The tangs and the windows are operative together to enable actuation forces to be selectively transferred from any group of selected ones of the control systems to the member via the tangs and the shoulders of corresponding ones of the windows for actuating the member while simultaneously permitting relative movement between the windows and the tangs corresponding to unselected ones of the control systems. A method of operating a valve assembly is also included.
