Abstract
An actuator assembly for moving a valve between an open position and a closed position includes an actuator housing forming at least a portion of a chamber. The actuator assembly also includes a support plate arranged within the actuator housing. The actuator assembly further includes a diaphragm coupled to the actuator housing and the support plate, the diaphragm expanding and contracting in response to a working fluid within the chamber. The actuator assembly also includes an indicator rod extending through the chamber and out of the actuator housing, the indicator rod being removably coupled to the support plate, wherein the indicator rod is arranged within an opening formed in the support plate, the indicator rod secured to the support plate via a coupling mechanism that releases the indicator rod in response to a pressure from the working fluid between the diaphragm and the support plate.
