Gearbox/valve shaft with parallel key
Information
Spigot at valve flanges should be loose fit.
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

Procedure
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].
3.
Apply a small quantity of grease to the valve or gearbox shaft [3].
