G-Series Manual Actuator used on BOS Butterfly Valves

Removing Actuator

Flow in the pipeline with the actuator removed can slam the valve closed causing personal

injury and damaging the flow system. Shut down the flow in the pipeline before removing the

actuator from the valve.

1. Discontinue flow and relieve pipeline pressure.

2. Close the valve.

3. Remove the four adaptor plate mounting screws (P4) and lockwashers (P10).

4. Remove the actuator from the adaptor plate (P1).

5. Do not loose the drive key used in the valve shaft and actuator gear.

Installing Actuator

Refer to Figure 2 and Figure 5 for parts identification.

1. Place the valve in the position it was in when the actuator was removed. Normally this will be in

the closed position.

2. Remove the screws (B1R) and pointer (B1Q).

3. Mount the actuator to the adaptor plate (P1) with the four mounting screws (P4) and

lockwashers (P10). Tighten screws.

4. Insert the drive key into the valve shaft/gear (B1C) keyway.

5. Fasten the pointer (B1Q) to the gear (B1C) with the two screws (B1R).

6. Check the closed position stop setting and readjust if necessary as described in the STOP

ADJUSTMENT Section of this Instruction.

7. Pipeline flow may now be restored.
