Short description 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 re-
taining ring.
When exchanging the output drive sleeve, later retrofitting to a different output drive
type is possible.
Spigot at valve flanges should be loose fit.

How to proceed 1. Check if mounting flanges fit together.
2. Check, if output drive of multi-turn actuator [1] matches the output drive of valve/
gearbox or valve/gearbox valve shaft [2/3].
