Abstract: Positioner assemblies may be configured to sense at least one position of at least a portion of a valve assembly that is moved along a first axis of movement. A movable element of the positioner assembly is configured to rotate about a second axis of movement, where the first axis of movement is substantially parallel to the second axis of movement. Valve systems and methods of sensing a position of a component of a valve system may include such a positioner assembly.
