Actuator can be mounted in any orientation when mounted onto a damper. When an actuator is mounted on a valve the actuator should not be mounted below horizontal on most valves in order to avoid water damage to the actuator that may occur if there is condensation or a water leak that travels along the piping and into the actuator. When an actuator is mounted on a globe valve, the actuator cannot be mounted lower than 45 degrees of center unless additional bracing is provided.
