5.6.1 Actuator mounting alternatives
Following mounting positions are possible:
Note
To prevent damage, do not fit the actuator with force.
1. Make sure that the butterfly valve is closed when using double acting and
closing spring loaded actuators.
2. Make sure that the butterfly valve is open when using opening spring loaded
actuators.
3. Lubricate the shaft and the key.
4. Fix the bracket to the actuator using the screws (
➔ Fig.5-11/3).
5. Assemble the actuator with the bracket on the desired position (A, B, C or D)
(
➔ Fig.5-12) onto the shaft of the butterfly valve body. Fix the unit with the
screws (
➔ Fig.5-11/6).
6. Connect the shaft’s end of the butterfly valve to the actuator using the
clamping ring (
➔ Fig.5-11/4). Assemble the clamping ring so that the yellow
markings show the position of the butterfly. When the valve is closed, the
markings must have an offset of 90° to the flow direction.
7. Tighten the bolts at the clamping ring (
➔ Fig.5-11/4).
8. Adjust the end positions afterwards (
➔Chap. 6.6).
