    Double acting actuator with spring

    Can a double acting actuator have a spring? If yes (for reaching the fail safe position), how is this construction better than single acting actuator?

  3. Generally double acting actuators don't have any spring for safety reason.these valve utilise with small air volume tank as power for fail safe position.normally the voulume calculate for 3 time open/close of the valves.
