11. Turn multi-turn actuator with handwheel in direction OPEN until valve flange and
output drive A are firmly placed together.
12. Tighten fastening screws [5] between valve and output drive type A crosswise ap-
plying a torque according to table.
4.3.2. Output drive types B
Application
●
For rotating, non-rising valve stem
●
Not capable of withstanding thrust
Design
Connection between hollow shaft and valve or gearbox via output drive sleeve fixed to
the hollow shaft of the multi-turn actuator via retaining ring.
Changing output drive sleeve allows later retrofitting to a different output drive type.
●
Output drive type B: Output drive sleeve with bore according to DIN 3210
●
Output drive types B1 – B4: Output drive sleeve with bore according to EN ISO
