GE Baker Hughes Masoneilan SVI FF Installation And Operation Manual page 56

3. Select mounting hole A, B, C or D for the stroke of the valve. For example, hole B is shown
in Figure 24 on page 56 for a size 10 actuator with 1.0" stroke. Unless otherwise specified,
the SVI FF mounting assumes that the actuator is in the normal upright position. The
mounting hole in the slotted opening of the mounting bracket must be left when facing
the actuator, with the actuator in the upright position.
4. Move the valve to its closed position. For air to extend, this requires using air pressure in
the actuator to fully stroke the actuator. For air to retract, actuators vent the actuator of
air pressure.
5. Thread the take-off rod to the actuator stem connector. Refer to Figure 25. Ensure that the
travel pointer located on the coupling is correctly positioned.
6. Attach the right hand threaded rod end to the SVI FF lever using a 1⁄4 - 20 x 1" cap screw
and nut as shown. The lever hole position to be used depends upon the specific valve
stroke. Refer to Figure 24 on page 56 and the Reciprocating Valve Linkage Selection,
Table 7 on page 57.
