Abstract
An apparatus is provided for a valve actuator assembly comprising an actuator housing, a piston, and a spring. The piston is disposed within the actuator housing. The piston is configured to couple to a valve element, and includes an inner cylindrical section and an outer cylindrical section. The outer cylindrical section of the piston is spaced apart from the inner cylindrical section to define a recess. The piston is further configured to move within the actuator housing in a first direction and a second direction, to thereby move the valve element toward a first position and a second position, respectively. The spring is disposed within the actuator housing, and is configured to supply a bias force that urges the piston to move in the first direction. The spring is at least partially disposed within the recess, and at least partially surrounding the inner cylindrical section.
