4.3.2.
Output drive types B and E
Application
●
For rotating, non-rising valve stem
●
Not capable of withstanding thrust
Design
For output drive types B/B1/B2, the connection to the valve or the gearbox is made
by directly placing the multi-turn actuator hollow shaft onto the input shaft of the valve
or gearbox.
For output drive types B3/B4/E, the connection is made via output drive sleeve which
is inserted into the bore of the hollow shaft of the multi-turn actuator and fixed by a
retaining ring.
When exchanging the output drive sleeve, later retrofitting to a different output drive
type is possible
