5. Refer to figure 2 and table 5 for available mounting styles and positions. The actuator is normally positioned
vertically with the valve in a horizontal pipeline.
6. Determine whether the actuator mounting yoke (key 27) will be mounted on the end plate assembly (key 3) side or
on the actuator housing boss side of the actuator. If the desired mounting position and style require moving the
mounting yoke (key 27) and travel indicator components to opposite sides of the actuator, remove the machine
screws (keys 20 and 22), the travel indicator scale (key 19), and the travel indicator (key 21). Remove the cap screws
(key 28) and the mounting yoke (key 27). Install the mounting yoke in the desired position (on the end plate
assembly or on the actuator housing boss). Tighten the mounting cap screws to the torque specified in table 6.
Install the travel indicator components on the opposite side of the actuator.
WARNING
To avoid personal injury or property damage, ensure the travel indicator is installed correctly to coincide with the desired
actuator action. Refer to figure 3 for more information.
