Mounting Actuator on Valve

Refer to Figures 1 and 2 for component identification.

Select one of the available actuator-to-valve mounting positions shown on the Installation

Drawing. Match the open or closed position of the valve with the open or closed position of

the actuator. Also, note the position of the word "open" on the top cover (B11). The cover must

be positioned on the housing (B1) so that dial hash mark for "open" will be parallel with the

pipeline when the valve is installed. One or more of the following four steps may be required,

depending upon the positions of the valve, the actuator, the actuator cover, and the mounting

position selected.

a. Rotate the valve shaft, and/or

b. Stroke the actuator, and/or

c. Select a different actuator-to-valve mounting position, and/or

d. Remove and re-index the cover. If this step is necessary, remove the four cover screws

B15), rotate the cover, and replace the four cover screws (B15) and washers (B14).

Tighten the screws to 15 ± 2 foot pounds (20 ± 3 Nm).

If the actuator does not include the collet assembly (the components are identified in Figure 1,

grease the components as described in the Actuator Reassembly section and install the

assembly as explained in steps 17 and 18 in the same section.
