4. Select mounting hole A, B, C or D for the stroke of the valve. For example, hole B is
shown in Figure 12 for a size 10 actuator with 1.0" stroke.

5. Move the valve to its closed position. For air to:
• Extend, this requires using air pressure in the actuator to fully stroke the actuator.
• Retract, actuators vent the actuator of air pressure.
6. Apply Loctite and thread the take-off rod to the actuator stem connector (Figure 13).
Ensure that the travel pointer located on the coupling is correctly positioned.
7. Attach the right hand threaded rod end to the lever using a 1/4 - 20 x 0.75" cap screw
and nut as shown in Figure 13. The lever hole position to be used depends upon the
specific valve stroke. Refer to Figure 12 and the Reciprocating Valve Linkage
Selection, Table 3 on page 31.
