Abstract
A valve actuator includes an actuator housing, a piston, a linkage assembly, a magnet, and a Hall sensor. The actuator housing is adapted to receive pressurized fluid. The piston is movably mounted within actuator housing, and is configured to translate in a first direction and a second direction. The linkage assembly is rotationally coupled to the piston and is adapted to couple to a valve element. The linkage assembly is configured to rotate the valve element in a first rotational direction and a second rotational direction in response to piston movement in the first direction and the second direction, respectively. The magnet is mounted on the piston and is movable therewith, and the Hall sensor is mounted on the actuator housing and is responsive to movement of the magnet to supply a position signal.
