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
applying 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.
When exchanging the output drive sleeve, later retrofitting to a different output drive
type is possible
●
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
5210
